- Multi‑protocol mocking (HTTP, gRPC, GraphQL, WebSocket, MQTT, SSE, SOAP) natively in one binary.
- Import from OpenAPI, Postman, HAR, WireMock, cURL, and WSDL files.
- Built‑in cloud tunnel for sharing local mocks over a single QUIC connection.
- Chaos engineering with 10 built‑in profiles (e.g., flaky, slow).
- Stateful CRUD with automatic ID generation and cross‑protocol data sharing.
- Proxy recording and replay of real API traffic.
- Web dashboard for visual mock management.
- 18 MCP tools for AI‑driven mock lifecycle management.

Setting up with Highlight

This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:

Download and install Highlight from highlightai.com/download
Navigate to the plugins tab and select "Add Custom Plugin"

From the repository

Start the MCP server by running mockd mcp (stdio transport). The server exposes 18 tools for full mock lifecycle management, including CRUD operations, import/export, chaos engineering, mock verification, and stateful resource management. You can then connect to it from any MCP‑compatible client or AI editor.

Claude Desktop / Cursor

Paste into your MCP client config file to install this server.
