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
Genesis - Pros & Cons
Pros
- ✓Unified physics across rigid/soft/fluid/cloth in one API — rare among simulators
- ✓GPU parallelism (10k+ envs/device) collapses RL training time dramatically
- ✓Python-native API designed for generative AI workflows from day one
- ✓Apache 2.0 licensing makes it safe for academic and commercial use
Cons
- ✗Young project — APIs still change between releases (pin versions)
- ✗Photoreal renderer is slower than rasterised options when raytracing is unnecessary
- ✗Documentation lags the rate of feature additions
- ✗Sim-to-real transfer is still the hardest open problem — Genesis improves but does not solve it
