ProspectAPIs

What ProspectAPIs MCP server does

ProspectAPIs connects MCP clients to the ProspectAPIs API for sales and prospecting workflows. Its tools cover four main areas: funding intelligence, prospect research, email verification, and watchlists. Additional tools expose account balance, live pricing, API version information, and a feedback endpoint.

Funding searches can be filtered by date range, round type, investment amount, company, domain, investor, and country. Results support limits from 1 to 100 and cursor-based pagination. A separate lookup retrieves a funding record by ID. Records include a public announcement URL when one exists.

Research jobs accept one company or person identifier, with a company name also required when searching by person name. Supported identifiers include a domain, website URL, company name, company LinkedIn URL, work email, or LinkedIn URL. An optional context string and purpose can tailor the request. Completed briefs are cited and intended for company or person research.

How it works

The package runs through npx as an MCP process. The client starts the process and supplies PROSPECTAPIS_API_KEY; the server then calls the configured ProspectAPIs API. PROSPECTAPIS_BASE_URL can replace the default API URL when needed.

Research submission returns a research ID immediately. The agent must poll the corresponding research result tool until the job is completed or failed; typical completion takes 20 to 90 seconds. Watchlists can deliver matching funding events to a webhook. A delivery consumes one record only when the webhook responds with HTTP 2xx.

Email verification supports one to 25 addresses per direct request. Results include status, reason, score, recommendation, charge state, and additional diagnostic fields. Larger checks can be created as jobs for up to 50,000 addresses, with paginated results of up to 1,000 records per page.

Setup and configuration

Node.js 22 or later is required. For Claude Code, register the process with:

claude mcp add prospectapis -e PROSPECTAPIS_API_KEY=pa_live_... -- npx -y prospectapis-mcp

Other MCP clients can run npx -y prospectapis-mcp and pass the key through their MCP server configuration. A typical configuration is:

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

PROSPECTAPIS_API_KEY is needed for all tools except pricing and API version. PROSPECTAPIS_BASE_URL defaults to https://api.prospectapis.com and is optional. Accounts begin with a free $1 balance and no card requirement. Usage is metered: funding records cost $0.02 each, valid or invalid email results cost $0.004, and completed research briefs use the price returned by the account or pricing tools.

Tools and capabilities

• Search and retrieve funding rounds with filters and pagination.
• Submit and poll cited research briefs for companies or people.
• Verify individual email batches or create bulk verification jobs.
• Report email outcomes and inspect verification statistics.
• Create, list, inspect, test, and delete watchlists and review deliveries.
• Check balance, retrieve pricing and API version data, and send product feedback.

Limitations and notes

Funding searches with no matches are free. Missing funding IDs are also free. Catch-all and unknown email results are not charged; insufficient balance can leave some requested addresses as unknown and uncharged. Research is charged only when a brief completes and is refunded if it fails. Watchlist management is free, but delivered events consume records under the webhook response condition described above.
