VS Code groundcheck Prompt/ground_before_answering

How to: VS Code groundcheck ground_before_answering

client:VS Code transport:streamable-http prompt:ground_before_answering

Add groundcheck to VS Code

  1. 01

    Open .vscode/mcp.json and merge this in. Keep any servers already there.

{
  "servers": {
    "groundcheck": {
      "type": "http",
      "url": "https://groundcheck.seiche.info/mcp"
    }
  }
}
  1. 02

    Save the file and restart VS Code.

  2. 03

    ground_before_answering is surfaced in the client's prompt or command menu. Unlike a tool, you invoke it deliberately — VS Code will not call it for you.

  3. 04

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

Requires agent mode. MCP: Open User Configuration puts the same block in every workspace. VS Code docs

Set these first

groundcheck will not start until these are set, so it never reaches VS Code.

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.
