  1. 02

    Save the file and restart VS Code.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that TokenLab MCP Server's identifier in your config matches the one above exactly.

VS Code prompts for each input the first time the server starts, so no secret is written to the file. VS Code docs

Set these first

TokenLab MCP Server will not start until these are set, so open_tokenlab_model_explorer never becomes available.

  • TOKENLAB_API_BASE
  • TOKENLAB_API_KEY
  • TOKENLAB_REQUEST_TIMEOUT_MS
  • TOKENLAB_MCP_TOOL_PROFILE
  • TOKENLAB_MCP_SCHEMA_MODE
  • TOKENLAB_MCP_MAX_FILE_BYTES
  • TOKENLAB_MCP_INLINE_BYTES
  • TOKENLAB_ARTIFACT_DIR
  • TOKENLAB_MANAGEMENT_TOKEN

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 18 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.
