Where hCaptcha is ahead

hCaptcha passes authentication documented, and Capsolver does not. That is understand, whether an agent can read the docs and work out how the API behaves before calling it.

What neither does

Both fail mcp discoverable, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, no mandatory sales call, programmatic credential creation, mcp integration available, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified. If your agent needs any of those, you will be building it yourself either way.
