saci.cc MCP server

Connect saci.cc to your AI agent and it can create temporary emails, wait for messages and read verification codes on its own. Useful for end-to-end tests of sign-up flows or for creating test accounts.

Server URL

https://saci.cc/api/mcp

Streamable HTTP transport, no auth.

How to connect

In your terminal:

claude mcp add --transport http saci https://saci.cc/api/mcp

In Claude (app or claude.ai), go to Settings → Connectors → Add custom connector and paste the server URL.

https://saci.cc/api/mcp

In ~/.cursor/mcp.json (or .cursor/mcp.json in the project):

{
  "mcpServers": {
    "saci": {
      "url": "https://saci.cc/api/mcp"
    }
  }
}

In .vscode/mcp.json:

{
  "servers": {
    "saci": {
      "type": "http",
      "url": "https://saci.cc/api/mcp"
    }
  }
}

In other clients that take a JSON config:

{
  "mcpServers": {
    "saci": {
      "type": "http",
      "url": "https://saci.cc/api/mcp"
    }
  }

Limits

Each call waits 25 seconds at most. The agent can call again to keep waiting.
The API's limits apply: 120 requests per minute per IP.
Emails are deleted about a day after they arrive, and anyone who knows an address can read its inbox.

Rather call the API directly? See the API docs
