What Pinecone does that Selectpdf does not
Pinecone passes llms-full.txt / full agent docs, mcp discoverable, structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, no mandatory sales call, agent-compatible signup flow, programmatic credential creation, cli available, mcp integration available, structured, predictable output, machine-readable errors, observable execution, agent compatibility verified, and Selectpdf 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
Selectpdf fails llms-full.txt / full agent docs, mcp discoverable, structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, no mandatory sales call, agent-compatible signup flow, programmatic credential creation, cli available, mcp integration available, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified. Each one is a place an unattended run stops, which is usually what sends someone looking in the first place.
Where Selectpdf loses the points
| Pillar | Selectpdf | What it measures |
|---|---|---|
| Discover | 80 | 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 | 52 | Signup, keys, SDKs, and whether a human has to be involved. |
| Operate | 24 | Rate-limit headers, errors, status, and behaviour under load. |
Selectpdf is weakest on operate at 24/100. Missing rate-limit headers mean an agent finds the limit by hitting it. If that is the part your agent depends on, take the ranking above seriously; if it is not, Selectpdf may still be the right pick.
What an agent runs into with Selectpdf
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.
- Ship an MCP server so agents can call you as a tool.
- Publish MCP install instructions so agents can discover the server.
- 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.
- Return request IDs and expose status/usage so runs are observable.
