Gives Claude/Codex SUPERPOWERS. AI agents evaluate Common Lisp code in a persistent, stateful REPL session over the Model Context Protocol (MCP). Our focus is simple: Empower your AGENT with a REPL. Agent is already good with file system access. Agent is smart. Agent decides how to use the REPL. Agent gets SuperPowers. Lisp Is Super Power --- What is This? CL-MCP-Server is an MCP server implementation that provides Claude with the ability to: - Evaluate Common Lisp expressions in a live REPL environment - Maintain persistent state across evaluations (functions, variables, loaded systems) - Capture rich output (return values, stdout, stderr, warnings, and on-demand backtraces) - Handle errors gracefully using Common Lisp's condition system - Support incremental development with stateful session management - Optimized for Token efficiency Unlike one-shot code execution, CL-MCP-Server provides a full REPL experience where definitions accumulate and state persists, enabling interactive exploratory programming through Claude. Value Proposition For Claude Users - NEW : Paren matching tools -- the agents struggle with lots of parens - Persistent REPL : Define functions once, use them repeatedly in the same session - 37 tools : full-on REPL power for evaluation, introspection, profiling, and more - Rich Error Reporting : Get concise default errors, with detailed backtraces and","default_branch":null,"files":null,"tree":[],"storefront":"/r/quasi","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/quasi/cl-mcp-server/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
