Pros	Only server that exercises the full MCP feature matrix in one place — tools, resources, prompts, sampling, elicitation, roots, logging, subscriptions, and Tasks Maintained by the Model Context Protocol project itself, so behavior tracks the spec as it evolves (SEP-1686 Tasks, Streamable HTTP, etc.) Runs anywhere an MCP client runs — npx, Docker, Claude Desktop, VS Code, Cursor, Windsurf — with stdio or HTTP transports TypeScript source is short and readable, making it a de-facto reference for how each handler should be shaped MIT-licensed, no telemetry, no signup, no cloud dependency Includes progress notifications and cancellation flows that most tutorial servers skip, so client cancel/timeout logic can be exercised properly	Zero-config bridge between any MCP client and a real Chromium instance, including JS-heavy SPAs that curl or fetch-based tools cannot see. Complete open-source TypeScript reference implementation, easy to fork as a starting point for a hardened production browser-MCP. Ships both NPX (headful, interactive login friendly) and Docker (headless, sandboxed) install paths. Screenshots are exposed as MCP resources with stable names, so a model can refer back to earlier captures across a conversation. puppeteer_evaluate gives the model an escape hatch to run arbitrary in-page JS when the fixed click/fill/select tool set is not enough. Console log resource lets the agent read runtime errors without a separate devtools bridge.
Cons	Explicitly not useful for end users — it does not do anything a human would actually want done Feature drift means some primitives (SEP-1686 Tasks, elicitation) may not yet be implemented in every client, producing red herrings during testing Documentation is a single features.md; there is no guided tour that maps each tool to the spec section it exercises TypeScript-only reference — Python or Rust client authors have to translate patterns themselves Sampling and elicitation flows depend on the client honoring them, so a silent client makes it hard to tell whether the server or the client is at fault	Archived on 29 May 2025 (read-only) and no longer maintained by Anthropic; expect Puppeteer/Chromium drift over time. Runs a browser on your machine with access to local files and localhost/private IPs, which is a real prompt-injection and SSRF risk if the model visits hostile pages. No built-in proxy rotation, stealth patches, CAPTCHA handling, or Cloudflare-turnstile bypass, so it is not suitable for anti-bot-hardened targets. Selector-based tools rely on the model producing correct CSS selectors; brittle on frequently-changing DOMs. No session persistence, cookie import, or multi-tab management primitives out of the box. Community forks (Playwright MCP, browserless MCP, hyperbrowser, etc.) have moved past this reference in features and active support.
