Common questions

Is ProspectAPIs safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: PROSPECTAPIS_API_KEY, Authorization

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.17.1) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

prospectapis-mcp

prospectapis-mcp is the MCP server for ProspectAPIs (https://prospectapis.com), for sales and prospecting teams and the AI agents they run in Claude Code, Claude Desktop, Cursor and other MCP clients. It gives your agent twenty-five tools over the ProspectAPIs API: search funding rounds by date, round, amount, company, investor and country, get new matching rounds pushed to your webhook, verify, find and bulk-check email addresses, report what bounced, and order a cited research brief on any company or person. Funding records carry the public announcement URL when there is one. Every account starts with a free $1 balance and no card: records cost $0.02, an email check $0.004 and a completed brief $0.15, with no seats and no subscription. 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

Tool	Endpoint	Cost
`funding_search`	`GET /v1/funding`	$0.02 per record returned; 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`
`email_verify`	`POST /v1/email/verify`	$0.004 per `valid` or `invalid` result; `catch-all` and `unknown` are free; 1 to 25 addresses a call
`email_verify_stats`	`GET /v1/email/verify/stats`	free
`email_outcomes_report`	`POST /v1/email/outcomes`	free; 1 to 100 outcomes a call
`email_verify_job_create`	`POST /v1/email/verify/jobs`	free to start; $0.004 per `valid` or `invalid` result as it is checked; up to 50,000 addresses
`email_verify_job_get`	`GET /v1/email/verify/jobs/:id`	free
`email_verify_job_results`	`GET /v1/email/verify/jobs/:id/results`	free; 1,000 a page
`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

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.

email_verify takes emails, a list of 1 to 25 addresses. Each result has status (valid, invalid, catch-all or unknown), reason, reason_text, score (0 to 100), recommendation (send, send_with_caution, retry_later or do_not_send), charged, flags, smtp_code and catch_all_tier. If the balance covers only some addresses, the rest come back unknown with reason not_checked_insufficient_credits and are not charged.
