Permit.io. Permissions for the AI era.

Where Mcp is ahead

Mcp passes self-service signup, and Permit.io does not. That is adopt, whether an agent can get a key and make its first successful call without a human in the loop.

It also holds operate: retry behavior documented and agent compatibility verified. Permit.io misses those.

Where Permit.io is ahead

Permit.io passes public docs discoverable, and Mcp 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, openapi / spec quality, request examples provided, response examples provided and errors and status codes documented. Mcp misses those.

And on adopt, agent-compatible signup flow, programmatic credential creation and copyable quickstart. Mcp misses those.

Finally, on operate, structured, predictable output and machine-readable errors. Mcp misses those.

What neither does

Both fail authentication documented, limits / constraints documented, no mandatory sales call, fast time to first request, idempotency support, rate-limit behavior predictable. If your agent needs any of those, you will be building it yourself either way.
