Please describe.**\n\n- Currently there seems to be no official MCP conformance test suite.\n- There are some internal tests for different implementations, e.g. fastmcp but no official testsuite.\n- It would be cool if we offer a automated (ci based) MCP conformance testsuite.\n- Ideally the tests should refer to the chapters/requirements in the specification.\n\n\n**Describe the solution you'd like**\nWe do not have to start a point zero because there are already:\n- MCP Inspector / Explorer (reference client)\n- internal testsuites of different MCP implementations e.g. fastmcp\nbased on these testsuites, it could be possible to implement a official testsuite.\n\n**Describe alternatives you've considered**\nna\n\n**Additional context**\n\n- the MCP community can work together, using the existing testsuites and \n- assemble a official MCP conformance testsuite\n\nPossible test:\n- Server startup\n- Capability discovery\n- Tool schema correctness\n- Tool invocation round-trips\n- Resource listing \u0026 fetching\n- Prompt exposure\n- JSON-RPC framing\n- Error propagation\n- Streaming responses\n- Cancellation handling\n ","author":{"url":"https://github.com/bmerkle","@type":"Person","name":"bmerkle"},"datePublished":"2025-12-17T20:14:50.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/1990/modelcontextprotocol/issues/1990"}
