Where Logto is ahead

Logto passes llms-full.txt / full agent docs, and Ory does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: structured api reference, authentication documented, pricing understandable and limits / constraints documented. Ory misses those.

And on adopt, self-service signup, agent-compatible signup flow and free trial or free allowance. Ory misses those.

Where Ory is ahead

Ory passes mcp discoverable, and Logto does not. That is discover, whether an agent can find the product at all without being told it exists.

And on operate, agent compatibility verified. Logto misses it.

What neither does

Both fail openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, programmatic credential creation, fast time to first request, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable. If your agent needs any of those, you will be building it yourself either way.
