Use cases

Use cases include serving static files for web development, testing API endpoints, and providing real-time updates to clients through SSE.

How to use

To use simpletool-server, set up the server by specifying the folder containing the files you want to serve. Then, run the server and access the files via the provided API endpoints.

Key features

Key features include easy file serving, support for SSE for real-time updates, and integration with OpenAPI for streamlined API documentation.

Where to use

simpletool-server is ideal for development environments where quick file access and sharing are needed, particularly for web applications and testing purposes.

MCPoSimpleServer

A Python-based LLM server that implements the Model Context Protocol (MCP).

🤔 What is MCPoSimpleServer?

MCPoSimpleServer is a lightweight, asynchronous API platform for running and managing MCP tools in isolated, secure environments. It implements the Model Context Protocol (MCP) for seamless integration with LLM applications.
