Mockserver
MCP server mock-server/mockserver-monorepo/com.mock-server/mockserver homepage
Mock, record/replay, verify and chaos-test any HTTP, REST, gRPC or LLM dependency over MCP.
No install line here. This server does not publish one we could copy, and it has no package name recorded, so anything shown here would be a guess at whether it runs from npm, PyPI, a container or a hosted URL.
The repository will have the real instructions: github.com/mock-server/mockserver-monorepo

Whose pick this was
Write against the API that exists today
Stands in for their API, and its real value is the part that sounds like a stunt: it can inject latency, drop connections and fail on purpose. Every integration ships a retry path and a rate-limit path that were never once executed, because provoking a 429 from a vendor deliberately is difficult and slightly rude.
