An MCP Server Is Not Interoperable Just Because It Connects

说明与用途

MCP 服务器测试应验证模式、错误状态、简洁内容和结构化数据，而不仅仅是连接。

问题

MCP handshake only confirms connection; it does not guarantee that the client can correctly use the tool, interpret responses, or detect errors.

结果

The smoke test confirms that the server advertises the correct schema, returns non‑error responses, provides concise content, and supplies deterministic structured data, ensuring better interoperability.

工作流

• 1. Call list_tools() and inspect input schema for each tool.
• 2. Verify CallToolResult.is_error is false for a sample call.
• 3. Check that content contains concise summary without full payload.
• 4. Inspect structured_content for required fields (response_type, completion, assistant_action, normalized locations, etc.).

证据

The test call returned is_error=false.

来源

The structured result carried destination normalization, product fields and workflow state.
