    Save the file and restart Claude.ai.

    postgres is surfaced in the connector's menu once the server is linked. Unlike a tool, you invoke it deliberately — Claude.ai will not call it for you.

  3. 04

    If it does not appear, check that pg aiguide is connected and that you are looking at its prompts rather than its tools.

Claude on the web takes a remote URL and completes OAuth in the browser. For a packaged server use Claude Desktop or Claude Code instead. Claude.ai docs

Same prompt, other clients

Read from the server itself, by connecting to it and calling prompts/list on 24 September 2026. A listing does not declare its prompts, so asking is the only way to know them, and this is what the server actually offers rather than what its listing claims. Names only are stored; connect the server for each prompt's arguments.
