Connect Gemini CLI

Add OpenPost to an installed Gemini CLI, then authorize the connection in your browser.

Configure the server

Merge this entry into ~/.gemini/settings.json:

{
  "mcpServers": {
    "openpost": {
      "httpUrl": "https://app.openpo.st/mcp",
      "oauth": { "enabled": true }
    }
  }
}

Use httpUrl for Streamable HTTP. Gemini's url field selects SSE, which is a different transport.

Check the connection

Restart Gemini CLI and run:

/mcp auth openpost

Complete the browser consent. Ask, "List my OpenPost workspaces," then name your workspace and request its connected accounts.

If it does not connect

Run /mcp auth openpost again for an expired login. The browser callback must reach the machine running Gemini CLI. For a remote shell or private instance, consider the local bridge.

See Gemini CLI MCP documentation for authentication and transport settings.
