Install

npx -y tc39-mcp

Assembled from the package metadata in the official MCP Registry (including any subcommand or flag the publisher lists). Some publishers do not list the subcommand that starts MCP mode, so confirm the command in the README, along with any required configuration and credentials, before connecting it to real data.

Offers a hosted remote endpoint: https://mcp.xyzzylabs.ai/tc39/mcp (streamable-http). No local install needed.
