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

exo (Exo Labs) - Pros & Cons

Pros

  • ✓Full data privacy — every token stays on your network
  • ✓One-time hardware cost beats hourly cloud pricing for steady workloads
  • ✓Drop-in OpenAI SDK compatibility means zero app rewrites
  • ✓Active open-source community and a credible commercial sponsor
  • ✓Works with consumer hardware you may already own (Mac Studio, Mac mini)

Cons

  • ✗Throughput per node is well below a hosted H100 — not for low-latency consumer products
  • ✗GPL licensing complicates commercial embedding for some teams
  • ✗Cluster setup still rewards networking knowledge despite auto-discovery
  • ✗Apple Silicon is the optimised path; mixed-vendor clusters are rougher
  • ✗No SLA or managed support unless you engage Exo Labs commercially
