Real estate leads, skip tracing, direct mail, SMS & email outreach, and marketing automations

Overview

AI-generated overview

Spur is a real-estate prospecting platform that lets an assistant search listings, skip-trace owners, and run SMS, email and direct-mail outreach.

What you can do
Search and preview live Zillow listings, parse plain-English queries into filters, and view property details or saved-property stats and lists. Save listings, organize them into property lists, and find or enrich owners with skip-traced phone, email and mailing addresses. Draft, preview, create and edit email, SMS and postcard templates, including tracked QR codes and the user's own images. Build and manage multi-step outreach workflows, enroll owners, send SMS, and review SMS conversations and outreach reports. Check billing, top up credits, change plans and confirm Stripe payments.
When to use it
Useful for real-estate agents or investors who want an assistant to research properties, find owner contact details, and design and run outreach campaigns across email, SMS and direct mail from one place.
Requirements
A remote MCP endpoint at mcp.usespur.com over streamable HTTP, with no packages, environment variables or headers declared. It acts on a Spur account with a credit-based plan; searches, enrichment, AI drafting, SMS and sends consume credits, and payments go through Stripe checkout.
Before you install
Many tools spend money or contact real people: enrichment, SMS, workflow activation and enrollment, postcard and letter sends, and billing top-ups. The server asks for explicit approval (confirm=true) and preview confirmation tokens, but the assistant should always show the exact message, recipients and cost first. Skip tracing collects personal contact data, and outreach sends data to third parties. Template deletion can break active workflows.

Installation

In SourceWeft

  1. Open Spur in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.usespur%2Fspur/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

spur_search_properties

Search properties

Search live listings (Zillow data) in Spur with plain English and/or structured filters, including event filters. Results show as cards and a map. Uses 1 property-search credit per call from the user's Spur plan, or 2 credits when the search makes more than 3 ZHomes calls (e.g. several event types, tax/sale-history events, or description-based filters). To check how a sentence will be interpreted before spending a credit, call spur_parse_search_query first. Examples: - "3 bed houses under $2,500/mo in Austin owned 10+ years" -> location="Austin, TX", listing_status="forRent", home_type="singleFamily", min_beds=3, max_price=2500, min_ownership_years=10 - "duplexes for sale in 78704 built before 1980 with absentee owners" -> location="78704", listing_status="forSale", home_type="multiFamily", max_year_built=1979, only_absentee=true - "new pre-foreclosures or price drops of 10%+ in Dallas this week" -> location="Dallas, TX", events=["preforeclosure","price_drop"], event_within_days=7, event_min_change_pct=10 - "motivated sellers in Houston: stale, back on market, or fired their agent" -> location="Houston, TX", events=["stale_listing","back_on_market","agent_to_fsbo"] Events (pass in `events`; a listing matches when ANY selected event fired, and is tagged with each): - Listing lifecycle: new_listing, coming_soon, coming_soon_active, price_drop, price_increase, pending, sold, back_on_market, delisted (automations only), open_house, rental_listed, rent_change, move_in_moved_up - Distress & motivation: preforeclosure, foreclosure, auction, bank_owned, distress_escalated, fsbo, agent_to_fsbo, stale_listing, new_construction - Valuation & tax: tax_assessment_posted, assessed_value_jump, tax_paid_dropped (weak), sale_recorded, zestimate_moved, equity_gap, price_below_assessed Direct events (price_drop, pending, sold, preforeclosure, fsbo, new_listing, …) work on the first search. Change events (price_increase, back_on_market, distress_escalated, agent_to_fsbo, ren

spur_parse_search_query

Preview search filters

Show how Spur interprets a plain-English property search (filters and events) without running it. Free: uses no search credit. Use it to confirm intent before spending a credit, or to turn a vague request into explicit filters you can adjust. The returned arguments can be passed straight to spur_search_properties (keep the same location / status unless the user says otherwise). Exclusions ("no condos", "not foreclosures") are honoured by leaving those filters out.

spur_create_workflow

Create outreach workflow

Create a multi-step outreach sequence from saved templates. It's saved as an inactive draft: nothing sends until it's activated (spur_set_workflow_active) and owners are enrolled. Send steps take a saved template: email/SMS from spur_list_message_templates (design new ones with spur_create_email_template / spur_create_sms_template), direct mail from the user's saved postcard or letter templates. Wait steps space them out. Reply/open/click branches can be added afterwards in Spur → Outreach. Example: "text, wait 2 days, email, wait 5 days, postcard" -> steps=[{type:"send_sms",template_id:…},{type:"wait",days:2},{type:"send_email",template_id:…},{type:"wait",days:5},{type:"send_direct_mail",template_id:…}]

Parameterstemplate_idrequired

spur_preview_message_template

Preview email or SMS template

Show a saved email (inbox view, desktop and mobile) or SMS (phone view, segment count) rendered with sample data or a real owner's data, plus design checks. Changes nothing.

Parametersowner_idtemplate_idrequired

spur_preview_message_draft

Preview unsaved email or SMS

Preview email HTML or SMS text before saving it: renders it with sample or real owner data and runs the design checks. Nothing is saved; iterate here, then save with spur_create_email_template / spur_create_sms_template. Email HTML guidance (see spur://email-design-guide): full HTML document, table-based layout 600px wide, inline styles on elements (a small <style> block in <head> is fine for resets/media queries), web-safe font stacks, no JavaScript, no forms, no external CSS. Images as absolute https URLs with alt text and width attributes. The user's own images (logo, headshot, property photos): spur_list_images gives their URLs; if they want to use an image they have, call spur_upload_image (or spur_save_image for a link) and use the saved URL. Use PNG or JPG in emails, not SVG. A hidden preheader <div style="display:none"> right after <body> sets the inbox snippet. Include an opt-out line ("Reply STOP" or an unsubscribe link) and the sender's postal address in the footer. Keep it under 50,000 characters. Use merge fields like {{owner_first_name}}, {{property_address}}, {{your_name}}, {{your_phone}}, {{company_name}} (see spur://merge-variables). The plain-text version is generated from the HTML unless you pass text_body. SMS guidance: plain text, ideally one segment (160 GSM characters, or 70 if it uses emoji or other non-GSM characters; longer messages are billed per segment). Identify yourself, keep it conversational, and include opt-out wording ("Reply STOP to opt out") on first-touch messages. Links in texts from unverified numbers can be blocked, so give link-free fallback_body text when the body has a URL. Use merge fields like {{owner_first_name}}, {{property_address}}, {{your_name}} (see spur://merge-variables).

Parametershtmltextchannelrequiredsubjectowner_idfallback_body

spur_create_email_template

Create email template

Save a new email template and show its inbox preview. Ways to start: - From blank: start_from_blank=true gives a tested 600px responsive layout with greeting, signature and a compliant footer; pass html to replace it. - Redesign: base_template_id copies one of the user's email templates. - From scratch: pass html (or only text_body for a plain-text email). The saved template can then be used by outreach workflows (spur_create_workflow / spur_set_workflow_step_template). Email HTML guidance (see spur://email-design-guide): full HTML document, table-based layout 600px wide, inline styles on elements (a small <style> block in <head> is fine for resets/media queries), web-safe font stacks, no JavaScript, no forms, no external CSS. Images as absolute https URLs with alt text and width attributes.

Parametershtmlnamerequiredsubjecttext_bodyis_defaultdescriptionbase_template_idstart_from_blank

spur_update_email_template

Edit email template

Edit one of the user's email templates and show the updated inbox preview. For tweaks pass replacements (exact find → replace in "html", "subject" or "text"); to redesign pass full html. When the HTML changes, the plain-text version is regenerated unless it was hand-written or you pass text_body. Workflows using this template send the new version from their next step. Example: replacements=[{target:"html", find:"<p style=\"margin:0 0 16px;\"></p>", replace:"<p style=\"margin:0 0 16px;\">I'd like to make a cash offer on {{property_address}}.</p>"}] Email HTML guidance (see spur://email-design-guide): full HTML document, table-based layout 600px wide, inline styles on elements (a small <style> block in <head> is fine for resets/media queries), web-safe font stacks, no JavaScript, no forms, no external CSS.

spur_create_sms_template

Create SMS template

Save a new SMS template and show its phone preview with segment count and checks. The saved template can then be used by outreach workflows (spur_create_workflow / spur_set_workflow_step_template). SMS guidance: plain text, ideally one segment (160 GSM characters, or 70 if it uses emoji or other non-GSM characters; longer messages are billed per segment). Identify yourself, keep it conversational, and include opt-out wording ("Reply STOP to opt out") on first-touch messages. Links in texts from unverified numbers can be blocked, so give link-free fallback_body text when the body has a URL. Use merge fields like {{owner_first_name}}, {{property_address}}, {{your_name}} (see spur://merge-variables).

Parametersconfirmrequiredtemplate_idrequired

spur_send_test_email

Send test email to yourself

Send an email template, filled with sample data (or one owner's data), to the user's own Spur account email from their email sender, to check it in a real inbox. Never goes to owners. Confirm with the user first.

Parametersconfirmrequiredowner_idsender_idtemplate_idrequired

spur_list_postcard_templates

List postcard templates

Postcard templates available to the user: their own (editable), Spur defaults, and Spur's built-in gallery. Copy a default or gallery design with spur_create_postcard_template base_template_id to redesign it, or start from blank with start_from_blank.

Parameterssizecategoryinclude_gallery

spur_get_postcard_template

Get postcard template HTML

Fetch a postcard template's HTML for reading or editing. For small text changes prefer spur_update_postcard_template with replacements instead of resending whole HTML.

Parameterssidetemplate_idrequired

spur_preview_postcard_template

Preview postcard template

Show any postcard template (yours, a Spur default or a gallery design) rendered with sample data, without changing anything.

Parameterstemplate_idrequired

spur_create_postcard_template

Create postcard template

Create a postcard template and show a preview. Three ways to start: - From blank: start_from_blank=true gives an empty, correctly sized canvas for the size (any side you pass HTML for replaces the blank side). - Redesign an existing template: base_template_id (yours, a Spur default or a gallery id) copies its HTML; override front_html/back_html/size as needed. - From scratch: pass both front_html and back_html. HTML guidance (see spur://postcard-design-guide): full HTML documents, inline <style>, no scripts. Fixed pixel sizing on html, body and a root .postcard at 300 px/in including 0.125" bleed: 6x4 → 1875×1275, 6x9 → 2775×1875, 6x11 → 3375×1875. Keep text 0.25" inside the edge. USPS clear zone on the back, measured from the bleed edges (Spur prints over it and covers anything there): postage 1.25"×1.25" in the top-right corner; address block 3.5"×2", 0.5" from the right edge and 1.35" from the top; USPS barcode strip 4.75"×0.625" along the bottom-right edge. Keep all text, logos, photos and QR codes out of it; a background color or texture under it is fine. The safe message area is left of the address block and above the barcode strip. Images as absolute https URLs. The user's own images (logo, headshot, property photos): spur_list_images gives their URLs; if they want to use an image they have, call spur_upload_image (or spur_save_image for a link) and use the saved URL. Use merge fields such as {{owner_first_name}}, {{property_address}}, {{your_name}}, {{your_phone}}, {{company_name}} (see spur://merge-variables). QR code box by default: unless the user says they don't want a QR code, every back you design includes an empty square <div class="qr-box"> in the message area (≥ 0.75in, e.g. 225×225 px at 300 px/in) with a short call to action beside it ("Scan to see your home's value"). Never write QR markup or {{qrUrl}} yourself: after saving, call spur_add_postcard_qr_code and the tracked QR fills the box (pick the code with spur_list_qr_codes, or ask the user w

Edit one of the user's postcard templates and show the updated preview. For text tweaks pass replacements (exact find → replace on a side); to redesign, pass full front_html/back_html. Spur default and gallery templates can't be edited: copy them first with spur_create_postcard_template base_template_id.

spur_add_postcard_qr_code

Add QR code to postcard

Put a tracked QR code on the back of one of the user's postcard templates and show the preview. Each mailed postcard gets its own code under the chosen QR code, so scans are tracked per recipient (spur_get_qr_code_activity). Placement: position="auto" fills the back's QR slot (an element with class qr-box, qr-code-box, qr-placeholder or qr-callout-box, as Spur's gallery designs have) and otherwise goes in the bottom-right of the message area, left of the address block and above the USPS barcode. Corners (top_left, top_right, bottom_left, bottom_right) and x_inches/y_inches place it in the message area; spots in the USPS clear zone are refused. Replaces any QR already on the card. If it lands on the message text, call again with another corner or move the text. Create a QR code first with spur_create_qr_code if spur_list_qr_codes has none that fits.

Parameterspositionx_inchesy_inchesqr_code_idrequiredsize_inchestemplate_idrequired

spur_remove_postcard_qr_code

Remove QR code from postcard

Remove the tracked QR code from one of the user's postcard templates (both sides) and show the preview. A QR slot from the design stays, empty.

Delete postcard template

Permanently delete one of the user's postcard templates. Spur defaults can't be deleted. Confirm with the user first.

Parametersconfirmrequiredtemplate_idrequired

spur_list_return_addresses

List return addresses

Return addresses saved for direct mail. The default one is used when a campaign doesn't specify one.

Takes no parameters.

spur_preview_postcard_campaign

Preview postcard mailing

Required step before mailing postcards. Renders the postcard with the first recipient's real data, checks which owners have mailing addresses, estimates the cost from the user's plan, and returns a confirmation_token. Show the preview, then ask the user to approve. Only after they approve, call spur_send_postcards with the token (the widget's Send button does the same). The token expires in 30 minutes and only covers this exact template, recipient set, return address and size.

Parameterssizeowner_idsrequiredtemplate_idrequiredreturn_address_id

spur_send_postcards

Send postcards

Mail the postcards approved in spur_preview_postcard_campaign. Irreversible and charges the user's account. Requires the preview's confirmation_token and the user's explicit approval (confirm=true).

Parametersconfirmrequiredconfirmation_tokenrequired

spur_list_qr_codes

List QR codes

The user's tracked QR codes: destination URL, colors, and which of their postcard templates print each one. Put one on a postcard with spur_add_postcard_qr_code; see scans with spur_get_qr_code_activity.

Takes no parameters.

spur_create_qr_code

Create QR code

Create a tracked QR code that sends scans to destination_url. Then add it to a postcard back with spur_add_postcard_qr_code; each mailed postcard gets its own code under it so scans are tracked per recipient.

Parametersnamerequireddestination_urlrequiredbackground_colorforeground_color

spur_update_qr_code

Edit QR code

Rename a QR code, change where scans go, or change its colors. A new destination also applies to postcards already mailed with this code. Templates pick up new colors at send time.

Parametersnameqr_code_idrequireddestination_urlbackground_colorforeground_color

spur_delete_qr_code

Delete QR code

Permanently delete a QR code. Refused while one of the user's postcard templates still prints it: remove it from those first with spur_remove_postcard_qr_code. Postcards already mailed keep redirecting. Confirm with the user first.

Parametersconfirmrequiredqr_code_idrequired

spur_get_qr_code_activity

QR code scans

Scan activity for a QR code: totals, which mailed recipients (owners) scanned their postcard, and recent scans of the code itself. Use it to find warm leads from a postcard campaign.

Parameterslimitqr_code_idrequired

spur_list_images

List images

The user's saved images (logos, headshots, property photos) with their public URLs, newest first. Use it as <img src="…"> (or a CSS background-image) in postcard, letter or email HTML. To add one, use spur_upload_image (from the user's device) or spur_save_image (from a URL).

Parameterslimit

spur_save_image

Save image from URL

Download an image from a public https URL (the user's website, a shared photo link) and save it to the user's Spur image library, so it stays available for printing and sending. Returns the saved image's URL. JPG, PNG, WebP, GIF or SVG, up to 20 MB. For a file on the user's device, use spur_upload_image instead. Only save images the user provided or asked for.

Parametersurlrequiredfilename

spur_upload_image

Upload image

Show an upload box where the user picks or drops an image from their device (logo, headshot, property photo); it's saved to their Spur image library. Use this whenever the user wants to use their own image, including one they attached to the chat: attachments don't reach Spur, so ask them to drop it into the box. After uploading, the user can click "Use this image", or call spur_list_images to get the URL.

Parameterspurpose

Show any letter template (yours, a Spur default or a gallery design) rendered with sample data, without changing anything.

Parameterstemplate_idrequired

spur_create_letter_template

Create letter template

Create a letter template and show a preview. Pick the letter type first (top_first_page or insert_blank_page); it decides where the address prints and how much of the page the design can use. Three ways to start: - From blank: start_from_blank=true gives an empty one-page letter laid out for the letter type. - Redesign an existing template: base_template_id (yours, a Spur default or a gallery id) copies its HTML and letter type; override html or letter_type as needed. - From scratch: pass html. HTML guidance (see spur://letter-design-guide): one US Letter page (8.5"×11"), full HTML document with inline <style>, "@page { size: 8.5in 11in; margin: 0; }", no scripts. One root <div class="letter"> 8.5in wide; px/in units only (no vh/vw); no box-shadow, transforms or manual page breaks. top_first_page: leave the first 3.15in blank (an empty <div class="address-zone" style="height:3.15in">), body ≈ 3–4 short paragraphs. insert_blank_page: no address zone; letterhead up to 1.8in, body up to ~400 words. Images as absolute https URLs. The user's own images (logo, headshot, property photos): spur_list_images gives their URLs; if they want to use an image they have, call spur_upload_image (or spur_save_image for a link) and use the saved URL. Use merge fields such as {{owner_first_name}}, {{property_address}}, {{your_name}}, {{your_phone}}, {{company_name}} (see spur://merge-variables).

spur_update_letter_template

Edit letter template

Edit one of the user's letter templates and show the updated preview. For text tweaks pass replacements (exact find → replace); to redesign, pass full html. letter_type switches between top_first_page and insert_blank_page. Spur default and gallery templates can't be edited: copy them first with spur_create_letter_template base_template_id. HTML guidance (see spur://letter-design-guide): one US Letter page (8.5"×11"), full HTML document with inline <style>, "@page { size: 8.5in 11in; margin: 0; }", no scripts. One root <div class="letter"> 8.5in wide; px/in units only (no vh/vw); no box-shadow, transforms or manual page breaks. top_first_page: leave the first 3.15in blank (an empty <div class="address-zone" style="height:3.15in">), body ≈ 3–4 short paragraphs. insert_blank_page: no address zone; letterhead up to 1.8in, body up to ~400 words. Images as absolute https URLs. The user's own images (logo, headshot, property photos): spur_list_images gives their URLs; if they want to use an image they have, call spur_upload_image (or spur_save_image for a link) and use the saved URL.

Parametershtmlnamecategorydescriptionletter_typetemplate_idrequiredreplacements

spur_delete_letter_template

Delete letter template

Permanently delete one of the user's letter templates. Spur defaults can't be deleted. Confirm with the user first.

Parametersconfirmrequiredtemplate_idrequired

spur_preview_letter_campaign

Preview letter mailing

Required step before mailing letters. Renders the letter with the first recipient's real data in its letter type's layout, checks which owners have mailing addresses, estimates the cost from the user's plan (Insert Blank Page letters include the extra address page), and returns a confirmation_token. Show the preview, then ask the user to approve. Only after they approve, call spur_send_letters with the token (the widget's Send button does the same). The token expires in 30 minutes and only covers this exact template, letter type, print options, recipient set and return address.

Parameterscolorowner_idsrequiredtemplate_idrequireddouble_sidedreturn_address_id

spur_send_letters

Send letters

Mail the letters approved in spur_preview_letter_campaign. Irreversible and charges the user's account. Requires the preview's confirmation_token and the user's explicit approval (confirm=true).

Parametersconfirmrequiredconfirmation_tokenrequired

spur_get_billing_summary

Billing summary

Plan, wallet balance, and this period's usage and remaining allowance per feature (searches, enrichment, SMS, postcards, letters, AI). Check this before large sends.

Takes no parameters.

spur_list_campaigns

List campaigns

The user's campaigns (bulk email, SMS, direct mail, outreach) with status and recipient progress.

Parameterslimitoffsetstatus

spur_get_campaign_stats

Campaign stats

Delivery and run statistics for one campaign.

Parameterscampaign_idrequired

spur_get_direct_mail_analytics

Direct mail analytics

Letters and postcards sent, delivered, in transit and returned, plus USPS tracking totals and spend.

Takes no parameters.

spur_show_billing_options

Top up or upgrade

Shows the user's wallet balance, one-click top-up amounts, auto-recharge status and every Spur plan with prices, in a widget with Pay/Upgrade buttons. Use whenever the user wants to add funds, buy credits, upgrade, change or compare plans, or a send failed for billing reasons.

Takes no parameters.

spur_top_up_wallet

Top up wallet

Creates a Stripe checkout link to add funds to the user's Spur wallet (pays for postcards, letters, SMS, enrichment and other usage beyond the plan). No money moves until the user pays on Stripe, so no confirmation is needed. If the user didn't name an amount, suggest $25, $50 or $100, or enough to cover the send they're planning.

Parametersamount_usdrequired

spur_change_plan

Upgrade or change plan

Moves the user to another Spur plan (ids from spur_show_billing_options; usually agent, team or brokerage). - No paid subscription yet: returns a Stripe checkout link. No confirmation needed. - Already subscribed: switches the plan immediately and charges or credits the prorated difference to the saved card. Call once without confirm to get the exact change, ask the user to approve it, then call again with confirm=true. - Moving to the free Solo plan returns a billing-portal link where the user cancels the paid subscription.

Parametersconfirmplan_idrequiredbilling_interval

spur_check_payment

Check payment

After the user pays a Stripe checkout link from spur_top_up_wallet or spur_change_plan, confirms the payment went through and returns the new wallet balance and plan. Safe to call repeatedly.

Parameterssession_idrequired

spur_manage_billing

Billing portal

Link to the user's Stripe billing portal: update the card on file, download invoices, change or cancel the subscription.

Takes no parameters.

spur_set_auto_recharge

Auto-recharge

Turns wallet auto-recharge on or off. When on, Spur charges the saved card amount_usd whenever the balance drops below threshold_usd, so sends never fail for lack of funds. Needs a saved card (the first spur_top_up_wallet payment saves one). Turning it on needs the user's approval of the amount and threshold (confirm=true); turning it off doesn't.

Parametersconfirmenabledrequiredamount_usdthreshold_usd

spur_list_search_automations

List search automations

Scheduled property searches with their schedule, filters, and next/last run times.

Takes no parameters.

spur_create_search_automation

Create search automation

Schedule a recurring property search. Every run uses 1 search credit, or 2 when it makes more than 3 ZHomes calls (several event types, tax/sale-history events, furnished-only or description-based filters). New matches can be saved to a list and enriched automatically (auto_enrich spends skip-trace credits on every run, so confirm with the user). Examples: - "every Monday 8am Central, Dallas rentals under $2k" -> frequency="weekly", day_of_week=1, run_time="08:00", timezone="America/Chicago", location="Dallas, TX", max_amount=2000 - "last Friday of each month" -> frequency="monthly", day_of_week=5, week_of_month=-1 - "every morning, new pre-foreclosures and price drops in Houston, save to my Distress list" -> frequency="daily", run_time="07:00", location="Houston, TX", events=["preforeclosure","price_drop"], list_id=… Accepts the same advanced and event filters as spur_search_properties (min_amount / max_amount instead of min_price / max_price). Run the search once with spur_search_properties first so the user can check the results before scheduling. In automations each event fires once, on the run that first sees it, so the same property isn't saved twice; change events start reporting from the second run. "delisted" is only available here. Events (pass in `events`; a listing matches when ANY selected event fired, and is tagged with each): - Listing lifecycle: new_listing, coming_soon, coming_soon_active, price_drop, price_increase, pending, sold, back_on_market, delisted (automations only), open_house, rental_listed, rent_change, move_in_moved_up - Distress & motivation: preforeclosure, foreclosure, auction, bank_owned, distress_escalated, fsbo, agent_to_fsbo, stale_listing, new_construction - Valuation & tax: tax_assessment_posted, assessed_value_jump, tax_paid_dropped (weak), sale_recorded, zestimate_moved, equity_gap, price_below_assessed Direct events (price_drop, pending, sold, preforeclosure, fsbo, new_listing, …) work on the first search.
