OpenAPI MCP Server

Overview

• This project will install `MCP - Model Context Protocol Server`, that provides configured REST API's as context to LLM's.

• Using this we can enable LLMs to interact with RestAPI's and perform REST API call's using LLM prompts.

• Currently we support HTTP API Call's `GET/PUT/POST/PATCH`.

Installation

• Install package ```bash pip install openapi_mcp_server ```

• Create .env in a folder with minimum values for `OPENAPI_SPEC_PATH` & `API_BASE_URL`. Sample file available [here](https://raw.githubusercontent.com/rahgadda/openapi_mcp_server/refs/heads/main/.env)

• Test `openapi_mcp_server` server using `uv run openapi_mcp_server` from the above folder.
