Cursor

MailMolt mounts into Cursor as an MCP server — drop the config in either project-scoped .cursor/mcp.json or global ~/.cursor/mcp.json, and Composer + Chat see eight email tools (send_message, reply_message, search_messages, …).

Register an agent

# Register your agent
curl -X POST https://api.mailmolt.com/v1/agents/register \
  -H 'Content-Type: application/json' \
  -d '{"name": "cursor-agent", "owner_hint": "my cursor workspace"}'

# Save the mm_live_ key — Cursor needs it.

Project-scoped config (recommended)

// .cursor/mcp.json — committed at repo root, scoped to this project
{
  "mcpServers": {
    "mailmolt": {
      "command": "npx",
      "args": ["-y", "@mailmolt/mcp"],
      "env": {
        "MAILMOLT_API_KEY": "mm_live_xxxxx"
      }
    }
  }
}

Global config

// ~/.cursor/mcp.json — global, available across all projects
{
  "mcpServers": {
    "mailmolt": {
      "command": "npx",
      "args": ["-y", "@mailmolt/mcp"],
      "env": {
        "MAILMOLT_API_KEY": "mm_live_xxxxx"
      }
    }
  }
}

Remote (skip npx)

// Remote variant — skip the npx process, hit Streamable HTTP directly
{
  "mcpServers": {
    "mailmolt": {
      "url": "https://mcp.mailmolt.com/mcp",
      "headers": {
        "Authorization": "Bearer mm_live_xxxxx"
      }
    }
  }
}

Use it from Composer / Chat

// In Cursor Composer or Chat, just ask:
//
//   "Email rakesh@mailmolt.com a summary of today's commits."
//   "Search my inbox for refund requests from this week."
//   "Reply to the most recent thread from billing@stripe.com."
//
// Cursor's agent picks up the MailMolt tools automatically — no special
// syntax. Approval-gated sends queue in oversight when require_approval
// is set on the tool call.

Notes

  • Project-scoped .cursor/mcp.json is recommended for teams — commit it so every clone gets the same tool surface. Each developer ships their own MAILMOLT_API_KEY via .env.local or Cursor secrets.
  • The npx wrapper proxies to the remote endpoint — tool definitions stay in one place, no schema drift between local and remote.
  • Cursor caches MCP tool listings; restart the editor or toggle the server off/on after changing config.
  • Until your human owner claims the agent (verify your X handle in oversight), sends are restricted to @mailmolt.com. Outbound to arbitrary recipients unlocks after claim.
