You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http findleademails https://www.findleademails.com/api/mcp --header 'Authorization: Bearer {api_key}'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "findleademails": {
      "url": "https://www.findleademails.com/api/mcp",
      "headers": {
        "Authorization": "Bearer {api_key}"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

Common questions

Is FindLeadEmails safe?

It passed 1 of 1 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: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 18 days ago.

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?

In the same category: Vexa, emailmd, MCP WhatsApp Cloud

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 YOUR_API_KEY. 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

Tool	What it does	Credits
`find_email`	Find and verify one person's work email from `first_name`, `last_name`, `company_domain` (or a LinkedIn company page URL).	1 only when the mailbox is verified
`verify_email`	Check one `email` you already have.	1 only when confirmed valid
`find_emails_bulk`	Find and verify a batch in one synchronous call (capped; returns `batch_too_large` above the cap).	1 per verified result
`create_job`	Queue a large list for background processing; returns a job id.	Reserves 1 per row, refunds unused
`get_job_status`	Progress and per-outcome counters for a job.	Free
`get_job_results`	A page of per-row results (page with `cursor` until `next_cursor` is null). Works while running.	Free

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.

Prefer an API key? Use the snippets below.

Setup with an API key

Replace YOUR_API_KEY with your key in every snippet.

Cursor

For OAuth, use the Add to Cursor button above. For an API key, add this by hand to .cursor/mcp.json (project) or ~/.cursor/mcp.json (global). The same file is in this repo as .mcp.json.

"mcpServers": { "findleademails": { "url": "https://www.findleademails.com/api/mcp", "headers": { "Authorization": "Bearer YOUR_API_KEY" } } } }

To keep the key out of the file, use "Bearer ${env:FINDLEADEMAILS_API_KEY}".

Claude Code

claude mcp add --transport http findleademails https://www.findleademails.com/api/mcp --header "Authorization: Bearer YOUR_API_KEY"

Claude Desktop

Claude Desktop needs the mcp-remote bridge (Node.js 18+). In claude_desktop_config.json:

"mcpServers": { "findleademails": { "command": "npx", "args": ["-y", "mcp-remote", "https://www.findleademails.com/api/mcp", "--header", "Authorization:${AUTH_HEADER}"], "env": { "AUTH_HEADER": "Bearer YOUR_API_KEY" } } } }

VS Code

.vscode/mcp.json. VS Code prompts for the key and stores it securely:

"inputs": [ { "type": "promptString", "id": "findleademails-api-key", "description": "Paste your FindLeadEmails API key.", "password": true } ], "servers": { "findleademails": { "type": "http", "url": "https://www.findleademails.com/api/mcp", "headers": { "Authorization": "Bearer ${input:findleademails-api-key}" } } } }

Windsurf

mcp_config.json (open it from the Cascade panel's actions menu; on macOS/Linux ~/.config/devin/mcp_config.json, on Windows %APPDATA%\devin\mcp_config.json):

"mcpServers": { "findleademails": { "serverUrl": "https://www.findleademails.com/api/mcp", "headers": { "Authorization": "Bearer YOUR_API_KEY" } } } }

Cline

Ask Cline to install this server from this repo (it follows llms-install.md), or add to cline_mcp_settings.json:

"mcpServers": { "findleademails": { "type": "streamableHttp", "url": "https://www.findleademails.com/api/mcp", "headers": { "Authorization": "Bearer YOUR_API_KEY" } } } }

Gemini CLI

gemini extensions install https://github.com/findleademails/findleademails-mcp

The CLI asks for your API key during install and stores it in the system keychain. Change it later with gemini extensions config findleademails.

Perplexity

Pro, Max or Enterprise: Connectors → add a custom remote connector and choose the authentication option your plan offers. With an API key:

URL: https://www.findleademails.com/api/mcp

Header: Authorization: Bearer YOUR_API_KEY

Grok

On grok.com: Connectors → New Connector → Custom, enter the server URL, and paste the API key when asked for authentication. Business and Enterprise workspaces need an admin to provision custom connectors first.

Grok CLI:

grok mcp add --transport http findleademails https://www.findleademails.com/api/mcp --header "Authorization: Bearer YOUR_API_KEY"

xAI API (the key goes in authorization without the word Bearer):

"type": "mcp", "server_url": "https://www.findleademails.com/api/mcp", "server_label": "findleademails", "authorization": "YOUR_API_KEY" }

Other clients

A client that supports OAuth only needs the URL. Any client that takes a remote URL plus headers: use the Cursor JSON above, adjusted to that client's key names.

Try it

curl https://www.findleademails.com/api/mcp \

-H "Content-Type: application/json" \ -H "Accept: application/json, text/event-stream" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}'

A tool call without a key or OAuth token returns HTTP 401 invalid_token (with a WWW-Authenticate header pointing OAuth clients to sign-in) and nothing is charged. A POST without Accept: application/json, text/event-stream returns 406.
