Connect Findymail without code

Findymail's docs confirm it works in Claude. You don't need a terminal or a config file. Check Findymail's docs first: some vendors give you a personal URL or an API key to use in place of the plain endpoint.

Claude (web and desktop app)

If Findymail shows up when you browse connectors in Claude, connect it from there instead. That skips steps 2 to 4.

In Claude, open Customize → Connectors.
Click + Add, then Add custom connector.
Name it “Findymail”, paste the server URL https://mcp.findymail.com/mcp, and click Continue.
Under Request headers, add your Findymail API key the way Findymail's docs describe, then click Add.
Click Connect. Then ask Claude something like “What can the Findymail connector do?”

On Team and Enterprise plans, an Owner adds the connector first under Organization settings → Connectors → Add → Custom → Web. Each person then connects it from Customize → Connectors. Free plans can add one custom connector.

Steps from the Claude Help Center: support.claude.com, checked 2026-10-16

From Findymail's docs: Claude Desktop setup is local stdio via claude_desktop_config.json with FINDYMAIL_API_KEY; Claude Code can use stdio or the HTTP endpoint with an Authorization: Bearer header.Source: npmjs.com, checked 2026-10-16

Developer setup (Claude Code, Cursor)

Add this to .mcp.json (Claude Code, project root) or ~/.cursor/mcp.json (Cursor). Remove the // comment line if your client requires strict JSON.

{
  "mcpServers": {
    "findymail": {
      "url": "https://mcp.findymail.com/mcp"
      // headless alternative: "headers": { "Authorization": "Bearer YOUR_FINDYMAIL_API_KEY" }
    }
  }
}

Add the endpoint to your client config (above), or as a custom connector in Claude.
Add your API key where the config shows the example value. Keep real keys out of shared or committed files.
Test it with a prompt like: “List the tools the Findymail MCP server exposes.”
