Shadow CLJS MCP

MCPOpen SourceMIT19.2

by Bigsy • DevOps & CI/CD

A small MCP server that connects to shadow-cljs to provide real-time build status, compilation details, and errors for LLM agents.

Example Use Cases

1
Verify that recent edits to ClojureScript files compiled successfully before suggesting further code changes or commits.
2
Detailed compilation diagnostics (errors, warnings, failing build details) to help debug ClojureScript build failures.
3
Report which files were recompiled and how long builds took to inform optimization or incremental development workflows.

Description

This MCP server monitors a running shadow-cljs instance (default localhost:9630) and exposes a tool to retrieve the last build status, including success/failure, compiled files, warnings, errors, and timing metrics. It is intended to be run alongside shadow-cljs and invoked by LLM agents after edits to ClojureScript files so they can verify builds and surface compilation issues. Installation is simple via npx and configurable host/port options.
