What Permit.io does that Stoplight does not
Permit.io passes clear canonical domain, clear product positioning, llms.txt published, llms-full.txt / full agent docs, mcp discoverable, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, programmatic credential creation, copyable quickstart, mcp integration available, machine-readable errors, and Stoplight 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
Stoplight fails clear canonical domain, clear product positioning, llms.txt published, llms-full.txt / full agent docs, mcp discoverable, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, no mandatory sales call, programmatic credential creation, fast time to first request, copyable quickstart, mcp integration available, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified. Each one is a place an unattended run stops, which is usually what sends someone looking in the first place.
Where Stoplight loses the points
| Pillar | Stoplight | What it measures |
|---|---|---|
| Discover | 53 | Can an agent find it at all: sitemap, robots, structured data. |
| Understand | 38 | Is there a spec, an llms.txt, a machine-readable description. |
| Adopt | 55 | Signup, keys, SDKs, and whether a human has to be involved. |
| Operate | 47 | Rate-limit headers, errors, status, and behaviour under load. |
Stoplight is weakest on understand at 38/100. 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, Stoplight may still be the right pick.
What an agent runs into with Stoplight
These are the findings from the last audit on 2026-09-01. Each one is a place unattended software stops, which is the practical reason to look at the list above.
- Ship an MCP server so agents can call you as a tool.
- Publish MCP install instructions so agents can discover the server.
- 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.
- Add /llms.txt so agents can find and read your capabilities.
- Publish an AGENTS.md or llms-full.txt with full agent context.
