prospectapis-mcp

prospectapis-mcp is the MCP server for ProspectAPIs, built for sales teams and their AI agents in Claude Code, Claude Desktop, Cursor and other MCP clients. It gives your agent fourteen tools over the ProspectAPIs API: search funding rounds by date, round, amount, company, investor and country, get new matching rounds pushed to your webhook, and order a cited research brief on any company or person. Every funding record carries the URL where the round was announced, when there is one. Records cost $0.02 each after 100 free a month, a completed brief costs $0.15, and there are no seats, no subscription and no card to sign up. It needs Node.js 22 or later.

Install (Claude Code): claude mcp add prospectapis -e PROSPECTAPIS_API_KEY=pa_live_... -- npx -y prospectapis-mcp

Other clients: run npx -y prospectapis-mcp with PROSPECTAPIS_API_KEY from https://prospectapis.com

Website: https://prospectapis.com/mcp

ToolEndpointCost
funding_searchGET /v1/funding$0.02 per record returned, after 100 free records a month; no match is free
funding_getGET /v1/funding/:id$0.02 when found; a missing id is free
research_submitPOST /v1/researchone research at research_price_usd (see account_balance), charged only when the brief completes; refunded on failure
research_getGET /v1/research/:idfree; poll until status is completed or failed
watchlist_create, watchlist_list, watchlist_get, watchlist_deliveries, watchlist_test, watchlist_delete/v1/watchlistsfree to manage; a delivered event costs one record, only when your webhook answers 2xx
account_balanceGET /v1/accountfree
feedback_sendPOST /v1/feedbackfree; reports a bug, wrong field or missing capability to the team (10 an hour per key)
pricing_getGET /pricingfree, no key needed; the live price list
api_versionGET /v1/versionfree, no key needed

funding_search filters: since, until (YYYY-MM-DD), round (comma list such as seed,series_a), min_amount_usd, max_amount_usd, company, domain, investor, country, limit (1 to 100) and cursor (the previous page's next_cursor, passed back unchanged).

research_submit takes exactly one prospect identifier (domain, website_url, company_name, company_linkedin_url, a work email or linkedin_url), or person_name with company_name, plus an optional context (your own product, at most 1,000 characters) and purpose (account_research, pre_call or outreach). It returns a research_id at once; a brief takes 20 to 90 seconds.

FAQ

Where does the funding data come from? Each record carries the URL where the round was announced, when there is one.

What is free? 100 funding records a month, any search that matches nothing, watchlist management, and the balance, pricing and version tools.

Which clients work? Claude Code, Claude Desktop, Cursor and any client that reads an mcpServers config, through npx -y prospectapis-mcp.

Develop

cd mcp
npm install
npm test        # mocked fetch over an in-memory MCP transport, no network
npm run check

The package is versioned independently of the API (SemVer, CHANGELOG.md in this folder). It is marked private so it cannot be published by accident; publishing is done only from the product's own npm identity.
