Windsurf A2UI Atomic Catalog render_ping

How to: Windsurf A2UI Atomic Catalog render_ping

client:Windsurf transport:streamable-http tool:render_ping

Add A2UI Atomic Catalog to Windsurf

  1. 01

    Open ~/.codeium/windsurf/mcp_config.json and merge this in. Keep any servers already there. 

{
  "mcpServers": {
    "catalog": {
      "serverUrl": "https://a2uicatalog.ai/mcp"
    }
  }
}
  1. 02

    Save the file and restart Windsurf.

  2. 03

    Ask for something render_ping does. Windsurf lists the server's tools on connect and calls render_ping itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that A2UI Atomic Catalog's identifier in your config matches the one above exactly.

Global only — Windsurf has no per-project MCP config. Refresh Cascade after saving. Windsurf docs

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 11 November 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
