Where Hookdeck is ahead

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

It also holds adopt: mcp integration available. Ahasend misses it.

What neither does

Both fail llms-full.txt / full agent docs, structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, agent-compatible signup flow, programmatic credential creation, official python sdk, machine-readable errors, rate-limit behavior predictable, agent compatibility verified. If your agent needs any of those, you will be building it yourself either way.
