Key Features
    • • Managed real browsers for agents to use interactive websites
    • • Search API and Fetch API for agent-focused web data retrieval
    • • Sandboxed Runtime for scalable agent deployments

    mcp.run - Pros & Cons

    Pros

    • ✓Wasm sandbox is a genuine supply-chain security win over npm-installed MCP servers
    • ✓Language-agnostic — author once, run everywhere
    • ✓Capability manifest gives you per-tool least-privilege
    • ✓Works with every major MCP client via a small local proxy
    • ✓Dylibso's Extism heritage means the Wasm tooling is mature

    Cons

    • ✗Wasm component model still requires a build step authors are learning
    • ✗Smaller catalog than Smithery for popular off-the-shelf servers
    • ✗Pricing model is still evolving
    • ✗Local proxy adds a (small) install step versus pure stdio servers

    Browserbase - Pros & Cons

    Pros

    • ✓Removes the worst parts of browser automation (proxies, captchas, anti-bot)
    • ✓Stagehand makes scrapers and agents resilient to UI changes
    • ✓Native MCP server is a one-line install for Claude Desktop and Cursor users
    • ✓Session video recording is invaluable for debugging agent failures
    • ✓Genuine production-grade reliability and concurrency

    Cons

    • ✗Per-hour pricing adds up fast for high-volume scraping use cases
    • ✗Overkill for simple HTTP scraping — Firecrawl/Crawl4AI may be cheaper
    • ✗Residential proxies and premium features are gated to enterprise tiers
    • ✗Stagehand LLM calls add latency vs hand-written Playwright selectors
    • ✗Vendor lock-in risk if you build deeply against Stagehand primitives
