Package conformance checks MCP results the way a strict client checks them, so a server fails here rather than in someone's editor.

Package httpcheck probes a Streamable HTTP MCP endpoint with hand-built requests and compares the answers with the transport rules of spec revision 2026-07-28: request metadata headers, error codes and HTTP status, Origin validation and the removal of sessions and GET streams.

Package scripting provides a simple script runner for testing MCP tools.

Package skillcheck lists the skills a server publishes (Skills extension, io.modelcontextprotocol/skills) and checks them against the extension and the Agent Skills format: manifests, frontmatter, digests, error codes.
