McpTools-listSchema-driftBreaking-changeAgent-compatibility

MCP schema drift and MCP tools/list compatibility gate for agent upgrades. Compares complete baseline and current snapshots; detects removed or renamed tools, new required arguments, incompatible input or output schemas, and model-facing metadata or safety-hint regressions. Returns an exact-hash compatibility verdict without fetching or invoking tools.

Using Roundhouse, tell me whether this x402 merchant is worth paying: how many distinct
agents have paid it, how recently, and for what.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
