Check whether your MCP server is ready for the MCP 2026-07-28 spec revision — breaking changes, deprecated features, migration hints.
This is a linter/migration tool (mcp-ready), not an MCP server. It analyzes fixture files to detect deprecated MCP patterns. The three 'tools' are actually test fixtures extracted from sample server code, not real tool definitions. Tool 'modern' has a description but no visible schema. Tool 'legacy' has no description. Tool 'demo' has an empty schema object with no properties. None are registered via a real MCP server framework, they are inferred from fixture files.
Modern registration
Tools are inferred from fixture files, not explicitly registered in a real MCP server.
'demo' tool has empty input schema (no properties defined). Does not meet minimum schema completeness.
No output schemas documented for any tool. LLMs cannot plan downstream calls without knowing return structure.
Inferred effective spec: <=2025-11-25.
