Connect Gemini CLI - Rings AI

Add it from the command line

gemini mcp add --transport http rings https://production-api.joinrings.com/mcp

Start gemini and run /mcp to see the server status and its tools. Gemini CLI discovers the OAuth endpoints, opens your browser to sign in, and stores the tokens in ~/.gemini/mcp-oauth-tokens.json. With an API key instead of OAuth:

gemini mcp add --transport http --header "x-api-key: $RINGS_API_KEY" rings https://production-api.joinrings.com/mcp

Or edit settings.json

Add the server to ~/.gemini/settings.json (global) or .gemini/settings.json (this project):

{
  "mcpServers": {
    "rings": {
      "httpUrl": "https://production-api.joinrings.com/mcp",
      "timeout": 30000
    }
  }
}

Use httpUrl for the Rings server. The url key means SSE transport, and Rings serves Streamable HTTP.

To pass an API key here instead:

{
  "mcpServers": {
    "rings": {
      "httpUrl": "https://production-api.joinrings.com/mcp",
      "headers": {
        "x-api-key": "YOUR_RINGS_API_KEY"
      }
    }
  }
}

Notes

/mcp inside a session lists connection state and every discovered tool — the quickest way to confirm the connector works.
Gemini CLI asks before each tool call. Setting "trust": true on the server skips those prompts; leave it off if the agent can perform writes.
