## Description

This MCP server provides a bridge between Anthropic's Model Control Protocol and Basilisp's nREPL server, allowing Claude Code to interact directly with a Basilisp REPL environment. It enables execution of Basilisp code (a Lisp dialect similar to Clojure that runs on the Python VM), retrieval of documentation, namespace exploration, and Python interoperability through a set of well-defined tools. The implementation features robust error handling, syntax highlighting for results, and comprehensive documentation to facilitate seamless interaction between AI assistants and Basilisp code execution environments.
