Sema is a Model Context Protocol (MCP) server: MCP tools for Sema — eval, compile, build, format, and docs for a Lisp with LLM primitives. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.
No credentials are required — it works out of the box. The current release is v1.35.0, published under the MIT license, with source at sema-lisp/sema on GitHub, where it has earned 39 stars.
You'll find Sema in the AI & Agents category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
