All scored in MCP Infrastructure.
What StackResolve does that Smithery does not
StackResolve passes clear canonical domain, llms-full.txt / full agent docs, structured api reference, openapi / spec quality, pricing understandable, request examples provided, response examples provided, errors and status codes documented, self-service signup, no mandatory sales call, programmatic credential creation, free trial or free allowance, fast time to first request, cli available, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, and Smithery fails them. That is the whole of the gap between the two scores, so if none of those matter to your agent the ranking above overstates the difference.
Why people look for an alternative
Smithery fails clear canonical domain, llms-full.txt / full agent docs, structured api reference, openapi / spec quality, pricing understandable, request examples provided, response examples provided, errors and status codes documented, self-service signup, no mandatory sales call, programmatic credential creation, free trial or free allowance, fast time to first request, cli available, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable. Each one is a place an unattended run stops, which is usually what sends someone looking in the first place.
Where Smithery loses the points
| Pillar | Smithery | What it measures |
|---|---|---|
| Discover | 87 | Can an agent find it at all: sitemap, robots, structured data. |
| Understand | 31 | Is there a spec, an llms.txt, a machine-readable description. |
| Adopt | 50 | Signup, keys, SDKs, and whether a human has to be involved. |
| Operate | 56 | Rate-limit headers, errors, status, and behaviour under load. |
Smithery is weakest on understand at 31/100. Without a spec an agent has to guess at endpoints, and it guesses wrong. If that is the part your agent depends on, take the ranking above seriously; if it is not, Smithery may still be the right pick.
What an agent runs into with Smithery
These are the findings from the last audit on 2026-08-22. Each one is a place unattended software stops, which is the practical reason to look at the list above.
- Make signup self-serve; an agent cannot sit through a sales call.
- Publish an OpenAPI spec so agents can generate a client.
- Flesh out the OpenAPI: paths, schemas, and descriptions.
- Document error responses as an enum in your OpenAPI.
- Let agents create API keys programmatically.
- Return X-RateLimit / Retry-After headers so agents pace themselves.
- Publish an AGENTS.md or llms-full.txt with full agent context.
- Add request examples to your API reference.
