About Sema

Sema is an MCP server published by sema-lang.com. MCP tools for Sema — eval, compile, build, format, and docs for a Lisp with LLM primitives.

It runs on your own machine: your AI client starts it from the MCP bundle package https://github.com/sema-lisp/sema/releases/download/v1.37.0/sema.mcpb at version 1.37.0.

It asks for no keys or passwords.

Version 1.37.0 was published on 9 October 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 7 automated checks on registry metadata: 4 pass, 0 warn, 0 fail, 3 info. How we check.

What it asks for

This server declares no environment variables, so it asks for no keys or settings.
