Mockzilla MCP

MCP server for Mockzilla - an open-source API mock server for OpenAPI specifications. Let Claude Code, Claude Desktop, Cursor, or Gemini CLI install Mockzilla, inspect OpenAPI specs, and spin up realistic local mock APIs in seconds. No account required for local use.

People who work with api simulation, developer tools and gemini cli and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.
