    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

    Arcade AI - Pros & Cons

    Pros

    • ✓Clear differentiation: focuses on authenticated tool use and enterprise-ready MCP runtime, not generic workflow automation
    • ✓Transparent pricing with a usable free Hobby tier and published Growth usage allowances
    • ✓Strong fit for developers building agents that must safely act in SaaS tools

    Cons

    • ✗Developer infrastructure product; non-technical teams will need engineering support to implement it well
    • ✗Usage-based pricing requires monitoring once agents run many authenticated actions
    • ✗The value depends on whether your agent roadmap actually needs MCP-compatible tool execution
