No install snippet on purpose. A working MCP config is a command, its arguments and an environment block — the last two are where API keys live, so this catalogue never stores them and cannot publish them. Follow the link above for the authors' own instructions.
MockServer is a single, self-hosted tool that mocks and proxies the services your application depends on. It is free and open-source, runs anywhere, and needs no SaaS account. MockServer supports chaos testing by injecting latency, errors, dropped connections, and malformed responses.
A built-in Model Context Protocol (MCP) server lets AI coding assistants drive the mock server in natural language. MockServer can verify that expected requests were or were not made as test assertions. It can generate mocks and validate traffic directly from an OpenAPI or Swagger specification.
