Overview

AI-generated overview

Remote MCP server for the Agent Company Index, letting an assistant search and evaluate sourced B2B software and service offerings, and manage a company's own…

What you can do
  • Browse and search published B2B offerings by need, in plain language or alphabetically
  • Read one offering's full sourced record: fit and non-fit, limitations, prerequisites, data residency, pricing visibility, contract terms
  • Evaluate a structured buyer situation (category, size, country, requirements) and get fit, possible fit or exclusion with reasons
  • Request a free listing for the company you act for, and send or correct its structured answers
  • Verify domain control by email code, DNS TXT record or well-known file, then check status and approve the draft revision
  • Request removal of a company's published profiles
When to use it
Useful when a user is choosing B2B software, a service provider or an agency and wants options backed by sourced facts and stated limitations rather than marketing. Also relevant for a company that wants to publish, update or remove its own entry in the index.
Requirements
Remote streamable HTTP endpoint; no package, environment variables or headers declared. Listing workflows need the company's domain, a work email address on that domain, and either an emailed code or a DNS TXT record or well-known verification file.
Before you install
Listing tools act on behalf of a company: request_listing, update_listing_answers, approve_listing and request_listing_removal change or remove published data. approve_listing accepts the Listing Terms for the exact draft revision, so show the user the draft and terms first. Removal requires a work email on the company domain and a confirmation link. Domain verification involves a code sent to a company address.

Installation

In SourceWeft

  1. Open Agent Company Index 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.agentcompanyindex%2Fdirectory/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

discover_offerings

Browse all offerings

Browse every published offering in the Agent Company Index (B2B software and services, sourced facts, explicit limitations), in stable alphabetical order. Prefer search_offerings when the user describes a need; use this to page through the whole index.

Parameterslimitcursorschema_versionrequired

get_offering

Get offering record

Get the full sourced record of one offering by slug: who it is for and not for, limitations, prerequisites, data residency, pricing visibility, contract terms, open questions, the company's relationship to ACI's operator, and a source with checked date for every claim. Use before recommending or comparing a provider.

Parametersslugrequiredschema_versionrequired

search_offerings

Search offerings

Use when a user is looking for a B2B software product, service provider or agency (e.g. "website maintenance for a small company in Germany", "time tracking with DATEV export") and wants options backed by sourced facts and stated limitations rather than marketing. Plain-language search over the Agent Company Index; returns matching offerings with the terms they matched. Order: offerings matching more of the query's words come first, then by name; offerings matching fewer than half as many words as the best match are left out. Payment, client status and ownership by ACI's operator are not inputs to the order. ACI publishes no scores and no paid positions. Follow up with get_offering for the full record.

Parameterslimitqueryrequiredschema_versionrequired

evaluate_situation

Evaluate buyer situation

Check a structured buyer situation (category, company size, country, requirements) against every published offering and get each offering's fit or exclusion with reasons, limitations and unknowns. Each result states its group: fit (fit_state strong_contextual_fit), possible fit (possible_fit), insufficient information (insufficient_information) or excluded (eligibility excluded, with the reason). The list is ordered by more documented fit reasons first, then fewer cautions, then fewer unknowns, then offering id; it is not sorted by group, so group the results by those fields when presenting them. Payment, client status and ownership by ACI's operator are not inputs to the order. ACI publishes no scores and no paid positions. Use when the situation maps to the schema categories; for plain-language needs use search_offerings. free_text is accepted but not interpreted: only the structured fields decide fit.

Parameterssituationrequiredschema_versionrequired

request_listing

Request company listing

List one offering of the company you act for in the Agent Company Index. Listing is free. Before calling, fill answers from the company's website and ask the user for the rest: what problem the offering solves (primary_problem), who it fits best (positive_fit) and who not (negative_fit), two to four use_cases, the countries it serves (market_country), support_languages and pricing_model. Leave out anything you cannot confirm; unanswered fields stay visible on the profile as open questions. Returns a reference and a private listing token: tell the user to keep both, the token is shown only once. work_email must be an address on the company's own domain that the user reads ([email protected]); a free-mail or other-domain address is refused at once, because the approval is recorded for a mailbox on the domain (a company without one writes to ACI). Domain control: ACI mails that address an 8-digit code that the user gives back to you (verify_listing_domain email_code); where no code can be sent, a DNS TXT record or a file. Show the user the returned option word for word. ACI then drafts the profile from the website in a few minutes (get_listing_status). Once a person who may act for the company approves one exact revision and accepts the Listing Terms (approve_listing), it is published automatically. Payment never changes fit or order.

update_listing_answers

Update listing answers

Send or correct the company's structured answers (the complete set; it replaces the previous one). Once a draft exists this requests changes: ACI prepares a new revision from the answers within a few minutes, and any earlier approval no longer counts. After publication the same call updates the published profile: ACI reads the website again and prepares a new revision (unchanged answers are fine); the public profile stays as it is until the company approves that revision and it passes the automated check. Put every fact you want changed into answers; a free-text note is kept with the request, is not published and does not change the draft by itself.

Parametersnoteanswersrequiredreferencerequiredlisting_tokenrequiredschema_versionrequired

verify_listing_domain

Verify listing domain

Prove control of the company domain for a listing request: pass email_code with the code the user received at the company address, or call without it after the DNS TXT record or the /.well-known/aci-verification.txt file is in place.

Parametersreferencerequiredemail_codelisting_tokenrequiredschema_versionrequired

get_listing_status

Get listing status

Read the state of a listing request and what to do next: the domain-proof options, the prepared draft with its revision digest (facts, which of them are company statements, what ACI checked itself, open questions), the Listing Terms the company accepts with its approval (listing_terms: version, url, sha256, summary), or the public URL once published (also while an update of it is being prepared). Show the user the draft and the Listing Terms summary with its link before asking for approval.

Parametersreferencerequiredlisting_tokenrequiredschema_versionrequired

approve_listing

Approve listing draft

Approve publication of the exact draft revision on behalf of the company and accept the Listing Terms (LT-2, https://agentcompanyindex.com/legal/listing-terms/lt-2) for it. Requires a verified domain. Before calling: show the user the draft, then the listing_terms summary and link from get_listing_status, and ask whether they may act for the company, approve this exact revision and accept the Listing Terms on the company's behalf. Call only after an explicit yes from that person; never on your own. Pass the approver's full name, role and the company's legal name. When the domain was confirmed with a DNS record or a file, also pass approver_email (an address on the company domain the approver reads): ACI mails it a confirmation link and publication waits for it. The approved revision is then published automatically, usually within minutes; the approver gets an email record of the approval and the terms. When the domain was confirmed with the emailed code, ACI sends a free monthly report (which AI assistants and systems retrieved the profile) to that address; set monthly_report to false if the user does not want it. Every report has an unsubscribe link.

request_listing_removal

Request listing removal

Remove a company from the Agent Company Index on behalf of that company. Give the company's domain and a work email address on exactly that domain (ask the user for it). ACI emails a private confirmation link to that address; once someone there opens it and presses Remove, every published profile of the domain goes offline within a few minutes and the company gets an email. Nothing changes without that confirmation. Profiles under an agreement with ACI's owner are checked by a person first.
