Missive MCP by usefulapi

Missive MCP by usefulapi

Manage Missive collaborative email and chat from Claude, Cursor, or any MCP client — read conversations, messages, comments, drafts and contacts, and create drafts, send email, and update conversations. Hosted, no local install: connect with your Missive API token.

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

Connect

• Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://missive.usefulapi.io/mcp.
• Claude Code: claude mcp add --transport http missive https://missive.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": {
    "missive": {
      "url": "https://missive.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 Missive credentials.

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

On first connect you'll paste your Missive API token (Missive → Preferences → API → Create a new token; requires a Productive plan). It's validated, stored per-user, and scoped to you — no keys in config files.
