Validate API design in Claude Code

You live in the CLI, and your API design should be just as precise. `validate_api_design` ensures your endpoints follow strict verb and versioning rules before you deploy. It catches bad design patterns early. You get immediate feedback on your REST standards without leaving your terminal session.

Enforce RFC 7807 in Claude Code

Standardized errors are non-negotiable for production services. This tool enforces these error contracts so your logs remain readable and your clients know exactly what failed. Claude Code uses these rules to structure your middleware. It keeps your error handling consistent across your entire codebase.

Define API constraints for Claude Code

You need to set max page sizes and response envelopes to keep your services stable. This MCP Server forces you to define these limits before the agent writes the implementation. It prevents unbounded resource usage. You define the constraints, and the agent builds the code to match them.
