What is MCP Clojure SDK?
This SDK provides tools and components to create MCP servers in Clojure, facilitating custom request handling, protocol validation, and client-server communication. It includes core server implementations, transport layers, error handling, and protocol specifications. Designed for flexibility, it supports different message types, data validation, and specialized request processing, making it suitable for building complex MCP-based applications such as data analysis, visualization, and automation services. Developers can extend or customize server behaviors, define protocols, and handle multiple communication methods. It also provides predefined examples for setting up servers for tasks like calculator operations, Vega-lite visualizations, and code analysis, offering a comprehensive toolkit for MCP service development in Clojure.
Who will use MCP Clojure SDK?
- Clojure developers building MCP servers
- Data scientists creating data visualization or analysis tools
- Automation engineers integrating MCP protocols
- Research institutions developing protocol-driven applications
