Installation

In SourceWeft

  1. Open Mailshake MCP by usefulapi in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.usefulapi%2Fmailshake/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

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:
json
{  "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.
