# OpenAPI Proxy

> Use this tool when you need to dynamically interact with APIs defined by OpenAPI or Swagger specifications, generating tools for each endpoint with validation and forwarding requests to a backend API. It solves problems of API integration, validation, and logging, accepting OpenAPI specifications as input and producing HTTP requests as output. Ideal for use cases requiring automated API client generation, API gateway functionality, or microservice communication, with support for Docker deployment.

## Description

Loads OpenAPI or Swagger specifications from URLs or local files at startup and dynamically generates one tool per API endpoint with full Zod schema validation. Forwards tool calls as HTTP requests to the configured backend API using Streamable HTTP transport. Supports endpoint filtering via include and exclude lists, correlation ID tracking for request logging, and configurable HTML-to-Markdown conversion for response processing. Deployable as a Docker container with pre-built images available on Docker Hub.
