How does this help with Model Context Protocol (MCP)?

It automates the creation of the tools.json configuration by mapping API endpoints and parameters directly to the MCP tool format.

Does this skill support OpenAPI 3.0?

Yes, it supports both OpenAPI v2 (Swagger) and v3 specifications for comprehensive schema analysis.

Can it handle Postman collections for legacy APIs?

Absolutely. It can parse Postman JSON collections and extract methods, headers, and auth requirements to create MCP mappings.

What are the technical requirements for these scripts?

You need Python 3.7+ with the pyyaml and jsonschema packages installed, along with jq for JSON processing.

Can I generate tools for both Python and TypeScript?

Yes, the skill includes specialized scripts to generate function signatures for both Python and TypeScript languages.

API Development

Analyzes OpenAPI and Postman specifications to automatically generate Model Context Protocol (MCP) tool definitions and function signatures.

The API Schema Analyzer streamlines the process of integrating external APIs into the Claude environment by parsing complex OpenAPI (Swagger) and Postman collection schemas. This skill automates the extraction of endpoints, methods, and parameters, converting them into precise function signatures for Python or TypeScript and mapping them directly to MCP tool definitions. It is an essential utility for developers looking to bridge the gap between static API documentation and functional AI tool-calling, significantly reducing the manual overhead of building custom integrations and ensuring type-safe interaction with backend services.
