What Attio does that Close does not
Attio passes clear product positioning, llms-full.txt / full agent docs, mcp discoverable, authentication documented, mcp integration available, and Close 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
Close fails clear product positioning, public docs discoverable, llms-full.txt / full agent docs, mcp discoverable, authentication documented, fast time to first request, copyable quickstart, official python sdk, cli available, mcp integration available, retry behavior documented, idempotency support. Each one is a place an unattended run stops, which is usually what sends someone looking in the first place.
Where Close loses the points
| Pillar | Close | What it measures |
|---|---|---|
| Discover | 53 | Can an agent find it at all: sitemap, robots, structured data. |
| Understand | 92 | Is there a spec, an llms.txt, a machine-readable description. |
| Adopt | 60 | Signup, keys, SDKs, and whether a human has to be involved. |
| Operate | 89 | Rate-limit headers, errors, status, and behaviour under load. |
Close is weakest on discover at 53/100. An agent that cannot find the docs never gets as far as the API. If that is the part your agent depends on, take the ranking above seriously; if it is not, Close may still be the right pick.
