tc39-mcp

Verified · 16 days ago

Independent MCP server for the TC39 specs (ECMA-262 + ECMA-402): clauses, search, diffs, history.

Install

claude mcp add --transport http tc39-mcp https://mcp.xyzzylabs.ai/tc39/mcp

Our take

This server is focused on the TC39 JavaScript and internationalization specs, exposing clause lookup, search, diffs, and history across ECMA-262 and ECMA-402. It is for language-tooling authors, JavaScript engine contributors, and developers who need source-of-truth spec access. The specialization is a positive quality signal for accuracy, but it remains a narrow tool with modest public traction so far.
