What the publisher says

From the Browser Compat repository's README, as published. We do not edit it. Read it on GitHub

@cyanheads/browser-compat-mcp-server Browser compatibility and Baseline status for any web feature — offline, from MDN's browser-compat-data, web-features, and caniuse. STDIO or Streamable HTTP. 5 Tools

Public Hosted Server: https://browser-compat.caseyjhand.com/mcp

Overview

Web platform compatibility for frontend work: per-browser support from MDN's @mdn/browser-compat-data, Baseline state and dates from web-features, and browserslist target resolution weighted by caniuse-lite usage figures. Every dataset ships inside the package, so there are no runtime network calls, no API key, no rate limit, and no upstream to be down — the same answers come back air-gapped. Runs as a stdio process, a local Streamable HTTP server, or the public hosted endpoint above.
