Gemini CLI

Gemini CLI supports MCP via its ~/.gemini/settings.json.

stdio

jsonc

{
  "mcpServers": {
    "bridgent-hello": {
      "command": "bridgent",
      "args": ["dev", "/abs/path/to/server.ts"]
    }
  }
}

Restart Gemini CLI → tools become available in agent prompts.

HTTP

jsonc

{
  "mcpServers": {
    "bridgent-hello": {
      "url": "http://127.0.0.1:3333/mcp"
    }
  }
}

Troubleshooting

Server registered but tools missing → verify bridgent --version; older Gemini CLI builds expected the legacy SSE transport — upgrade Gemini CLI or run Bridgent's streamable-http mode (default in v0.1+)
Path issues on Windows → quote the path in args and use forward slashes
