VS Code TokenZero workspace_metrics

How to: VS Code TokenZero workspace_metrics

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

Add TokenZero to VS Code

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

{
  "servers": {
    "mcp": {
      "type": "http",
      "url": "https://api.tokenzero.sh/mcp"
    }
  }
}

02
Save the file and restart VS Code.
03
Ask for something workspace_metrics does. VS Code lists the server's tools on connect and calls workspace_metrics itself — you do not invoke it by name.
04
If nothing happens, check the server is running and that TokenZero'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

TokenZero will not start until these are set, so workspace_metrics never becomes available.

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 26 October 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.
