What Cloudflare does that Filestack does not

Cloudflare passes llms-full.txt / full agent docs, mcp discoverable, structured api reference, cli available, mcp integration available, agent compatibility verified, and Filestack 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

Filestack 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, programmatic credential creation, cli available, mcp integration available, structured, predictable output, 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.
