Overview

AI-generated overview

Remote Apify MCP server that pulls recent US building permits from nine city open-data portals into one unified schema.

What you can do
  • Fetch recent building and construction permits from nine major US cities in a single run.
  • Filter by jurisdiction list, issue date window (sinceDays) and a per-city record cap.
  • Receive each permit in one unified schema: permit number and type, work description, valuation, contractor and owner names, address, coordinates, issue date and status.
  • Get null for fields a given city does not publish.
When to use it
Useful for construction lead generation, contractor prospecting, market and competitive intelligence, or real-estate research where you want a recurring feed of newly issued permits across several US cities without querying each portal separately.
Requirements
Runs as a remote streamable HTTP endpoint at mcp.apify.com with OAuth authentication required. An Apify account is implied by the pay-per-event pricing. No environment variables or headers are declared.
Before you install
Priced pay-per-event: you pay per permit returned, so large runs or high per-city caps cost more. Data comes from public government open-data portals and some fields may be missing (null). Scheduling repeated runs adds recurring charges.

Installation

In SourceWeft

  1. Open US Building Permit Aggregator in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. 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/io.github.dizzyvinci%2Fbuilding-permit-aggregator/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

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

US Building Permit Aggregator — Multi-City Construction Leads

Pull recent building & construction permits from 9 major US cities in one clean, unified schema — straight from official open-data portals. One run, one format, every city.

Who uses this

  • Construction lead generation — find newly permitted projects (roofing, HVAC, solar, remodels) before competitors; sell to suppliers and subcontractors.
  • Market & competitive intelligence — track construction valuation and volume by city, contractor, and work type.
  • Real-estate & investment research — spot new development and renovation activity by neighborhood.
  • Contractor prospecting — surface active contractors and project owners by area.

Coverage (v1)

Chicago, Los Angeles, Austin, San Francisco, Seattle, Washington DC, Nashville, Philadelphia, Boston — and growing. All data comes from public government open-data APIs (Socrata, ArcGIS, Carto, CKAN); no login or paywall.

Unified output schema

Every permit, regardless of source city, comes back as:

json
{  "jurisdiction": "Chicago", "state": "IL", "sourcePortal": "socrata",  "permitNumber": "100-XYZ", "permitType": "NEW CONSTRUCTION",  "workDescription": "New 3-story residential", "valuation": 250000,  "contractorName": "ACME BUILDERS", "ownerName": null,  "address": "123 N STATE ST", "city": "Chicago", "zip": null,  "latitude": 41.9, "longitude": -87.6,  "issueDate": "2025-05-01", "status": null,  "scrapedAt": "2026-06-02T12:00:00.000Z"}

Fields a given city doesn't publish come back as null (e.g., some cities don't expose contractor or valuation).

Input

FieldTypeDescription
jurisdictionsarray["all"], or specific ids (e.g. ["chicago","nyc"])
sinceDaysintegerOnly permits issued in the last N days (default 30; 0 = no date filter)
maxRecordsPerJurisdictionintegerCap per city per run (default 1000)

Notes

  • Priced pay-per-event: you pay per permit returned. No subscription.
  • Schedule it (e.g. daily, sinceDays: 1) to build a fresh permit feed for your market.
