/mcp

Opens the MCP server manager.

/mcp belongs to the Tools & Tasks category and opens a panel for managing connected MCP servers (stdio and remote via serverUrl), including connection status. Configuration lives separately in a global file (~/.gemini/config/mcp_config.json) and a workspace file (.agents/mcp_config.json).

✅ WHEN TO USE IT?

Check connected MCP servers and their status

Open /mcp to see whether a server is connected

⛔ WHEN NOT TO?

You want to set a permission for a single MCP tool

/mcp manages server connections; the granular mcp(server/tool) rules are handled through permissions management.

Better: /permissions
