Practical solution for MCP protocol development using mcp-ui
mcp-ui provides developers with the following quick path to verify the MCP protocol:
- Simulation Tool Call: Modification
mcp_server.jshit the nail on the headmockToolsIf the parameter is true, you can test the tool call flow without the real API and return the preset response. - debug mode: Add at startup
DEBUG=mcp:*environment variable, the terminal will display the full protocol interaction log (including JSON-RPC requests/responses). - automated test: Use the project's built-in
test/mcp.test.jsSample cases to write test cases via Jest to cover scenarios such as tool registration, parameter validation, error handling, etc.
Typical Validation Cases:
- Test multi-tool chain calls (e.g., search before generating reports).
- Verify the large file chunking transfer function.
- Simulating timeout handling under network latency.
Efficiency Tips:
- Combined with Postman's direct reporting to the
