ProspectAPIs MCP

prospectapis-mcp

MCP server for the ProspectAPIs funding data and research API. It gives an MCP client (Claude Desktop, Claude Code, Cursor and others) fourteen tools over https://api.prospectapis.com, one per customer endpoint (the liveness probe GET /health has none; api_version answers the same question). Five tools change state: research_submit (starts a paid research job), watchlist_create, watchlist_test, watchlist_delete and feedback_send; every other tool only reads.

Tool	Endpoint	Cost
funding_search	GET /v1/funding	$0.02 per record returned, after 100 free records a month; no match is free
funding_get	GET /v1/funding/:id	$0.02 when found; a missing id is free
research_submit	POST /v1/research	one research at research_price_usd (see account_balance), charged only when the brief completes; refunded on failure
research_get	GET /v1/research/:id	free; poll until status is completed or failed
watchlist_create, watchlist_list, watchlist_get, watchlist_deliveries, watchlist_test, watchlist_delete	/v1/watchlists	free to manage; a delivered event costs one record, only when your webhook answers 2xx
account_balance	GET /v1/account	free
feedback_send	POST /v1/feedback	free; reports a bug, wrong field or missing capability to the team (10 an hour per key)
pricing_get	GET /pricing	free, no key needed; the live price list
api_version	GET /v1/version	free, 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.

Configure

Variable	Required	Default
PROSPECTAPIS_API_KEY	yes (all tools except pricing_get and api_version)	none
PROSPECTAPIS_BASE_URL	no	https://api.prospectapis.com

Client config (for example claude_desktop_config.json):

{
  "mcpServers": {
    "prospectapis": {
      "command": "npx",
      "args": ["-y", "prospectapis-mcp"],
      "env": { "PROSPECTAPIS_API_KEY": "pa_live_..." }
    }
  }
}

Claude Code: claude mcp add prospectapis -e PROSPECTAPIS_API_KEY=pa_live_... -- 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.
