Wire ll-lang into Claude Code, Cursor, or Zed in 30 Seconds

If you want an LLM to write ll-lang productively, the best setup is not "open a terminal and hope the model can parse shell output." The better setup is MCP.

ll-lang ships with a built-in MCP server through lllc mcp , so your editor can call the compiler and project tooling as structured tools.

That means your agent can ask questions like:

does this compile?

what does E005 mean?

where is this symbol defined?

what targets can I build to?

And get structured JSON back instead of scraped terminal text.

1. Add the MCP server

Use the current config shape from the ll-lang README and MCP user guide:

{ "mcpServers" : { "ll-lang" : { "command" : "lllc" , "args" : [ "mcp" ] } } }

Enter fullscreen mode

Exit fullscreen mode

If lllc is not on your $PATH , replace command with the absolute path to the binary.…
