mcp-lint

Lint MCP server tool schemas for cross-client compatibility across Claude, Cursor, Gemini, VS Code Copilot, Windsurf, Cline, OpenAI Agents SDK, and Continue.dev. Current stable version: 0.4.0 (MIT). mcp-lint provides static analysis and runtime preflight checks to catch JSON Schema quirks and client-specific incompatibilities before deployment. Ships TypeScript types and supports JSON/YAML input, auto-fix, compatibility matrix output, and rule explainability. Requires Node >=20. Key differentiator: unlike generic JSON Schema validators, mcp-lint is aware of each MCP client's unique schema expectations and known limitations.
