VS Code litmus request_grade

How to: VS Code litmus request_grade

client:VS Code transport:streamable-http tool:request_grade

Add litmus to VS Code

01
Open .vscode/mcp.json and merge this in. Keep any servers already there.

{
  "servers": {
    "litmus": {
      "type": "http",
      "url": "https://polygraph.so/api/mcp"
    }
  }
}

02
Save the file and restart VS Code.
03
Ask for something request_grade does. VS Code lists the server's tools on connect and calls request_grade itself — you do not invoke it by name.
04
If nothing happens, check the server is running and that litmus's identifier in your config matches the one above exactly.

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

Set these first

litmus will not start until these are set, so request_grade never becomes available.

POLYGRAPH_API_URL
NEXT_PUBLIC_POLYGRAPH_NETWORK

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 24 September 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.
