Tools

The browser talks to /mcp over Streamable HTTP, the same JSON-RPC protocol MCP Inspector and Antigravity use. Pick an item on the left.

Every change to the notes board, from the browser or from MCP clients, streamed live over Server-Sent Events.

Antigravity IDE

Add this entry to ~/.gemini/config/mcp_config.json, then reload MCP servers.

Then try asking the agent: "Add a note to review the release checklist, tagged work", and watch it appear on the Notes board.

MCP Inspector
