AI Developer Tool / MCP Server

An MCP server that gives agents a sandboxed Lisp REPL

A blog post describing ptc_runner’s MCP server and code-mode approach, where agents run short-lived untrusted programs inside a small Lisp REPL instead of Python or JavaScript.

Why it was accepted

The page clearly describes an AI-adjacent developer tool: an MCP server for agent code execution. It explains the purpose, the sandbox model, the Lisp-based execution environment, and how clients can use the server via tools like lisp_eval. There is enough visible detail to support a useful public listing.

Weakness

The snapshot does not show installation steps, supported clients beyond general MCP compatibility, pricing/licensing, or a complete command/config example. The visible example also cuts off before showing the full code mode flow.
