Mailshake MCP by usefulapi

Mailshake MCP by usefulapi

Use your Mailshake account from Claude, Cursor, or any MCP client. Read campaigns, replies, leads and activity, pause or resume campaigns and recipients, and close, ignore or reopen leads. Hosted, no local install: connect with your own credentials.

Live endpoint: https://mailshake.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://mailshake.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http mailshake https://mailshake.usefulapi.io/mcp, then run /mcp to log in.
• VS Code: Add to VS Code.
• Cursor and other clients: add the URL as a remote MCP server:

{
  "mcpServers": {
    "mailshake": {
      "url": "https://mailshake.usefulapi.io/mcp"
    }
  }
}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Mailshake credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/mailshake/

On first connect you provide your Mailshake API key, created in Mailshake under Extensions → API. The server validates it and stores it per user. No keys go in config files.
