FindLeadEmails tools (6, 3 write)

write = sends, deletes, buys or posts
  • create_jobwrite actionFree

    Queue a large list and return a job id. Reserves one credit per row up front and refunds what rows do not use. If the wallet cannot cover every row, the job is refused up front (no partial queue) with insufficient_credits and https://www.findleademails.com/pricing. Poll get_job_status, then page get_job_results. Each call creates a new job.

  • find_emailwrite actionFree

    Find and verify one person's work email from their name and company domain, or from a LinkedIn company page URL when you do not have the domain. Costs 1 credit only when the result is verified. Misses, catch-alls, and cached repeats are free and still return at 0 credits. A billable result fails at 0 balance; the error includes https://www.findleademails.com/pricing. This stores the lookup. It does not delete or modify the person's data.

  • find_emails_bulkFree

    Find and verify emails for up to 100 people. Use create_job for a larger list. 1 credit per verified result. Free outcomes still return at 0 credits. Rows run until a billable result cannot be paid for; later rows are skipped with insufficient_credits and https://www.findleademails.com/pricing. This stores the lookups. It does not delete data.

  • get_job_resultsFree

    Read one page of a job's per-row results. Readable while the job is still running. Pass cursor back as the next cursor until next_cursor is null. Does not spend credits and does not change the job.

  • get_job_statusFree

    Read progress and per-outcome counters for a job created with create_job. Does not spend credits and does not change the job.

  • verify_emailwrite actionFree

    Check whether one email address is a real mailbox. Costs 1 credit only when the mailbox is confirmed valid. Invalid, catch-all, unknown, and repeats are free and still return at 0 credits. A new valid mailbox fails at 0 balance; the error includes https://www.findleademails.com/pricing. The credit is spent after a valid result. This does not modify the mailbox.

FindLeadEmails MCP server

Find and verify B2B work emails from your AI assistant: single lookups or bulk lists, with deliverability checks.

This repository holds setup docs and config for the hosted FindLeadEmails MCP server. There is no code to install: the server is remote.

  • URL: https://www.findleademails.com/api/mcp (Streamable HTTP)
  • Auth: sign in with OAuth 2.1 in clients that support it (Claude, ChatGPT, Codex, VS Code, Cursor, Claude Code, Gemini CLI, and others): add the URL with no header and approve in the browser. Or send Authorization: Bearer YOURAPIKEY. Listing tools (initialize, tools/list) needs neither.
  • API key (only if you don't use OAuth): sign in and create one at https://www.findleademails.com/developers?utm_source=github. It is shown once; rotate it there if lost. Never commit it.

Use the www host. https://findleademails.com redirects, and some clients drop the Authorization header when following that redirect.

Both buttons add the server URL only. Approve the OAuth sign-in in your browser the first time a tool runs.

Tools

Pricing: misses, catch-alls, predicted results and repeat lookups are free; you pay only for verified emails. Credits never expire. See https://www.findleademails.com/docs/mcp?utm_source=github#credits.

Sign in with OAuth

The server supports OAuth 2.1 with PKCE (S256), Client ID Metadata Documents, and Dynamic Client Registration. In a client that supports OAuth, add the URL with no Authorization header and approve access in your browser. No API key needed.

  • Claude (claude.ai and Claude Desktop): Settings → Connectors → Add custom connector. Paste https://www.findleademails.com/api/mcp, choose "Sign in when needed", and keep "Use Claude's published identity".
  • ChatGPT and Codex: add the server with the URL above and choose OAuth as the authentication method.
  • Claude Code:
claude mcp add --transport http findleademails https://www.findleademails.com/api/mcp

Then run /mcp in Claude Code, select findleademails, and choose Authenticate.

  • VS Code and Cursor: add the URL only, with no headers (or use the install buttons above). The client opens the sign-in page when needed.
  • Gemini CLI: after installing the extension, run /mcp auth findleademails.
