shadow-cljs-mcp

npm version

A Model Context Protocol (MCP) server that monitors shadow-cljs builds and provides real-time build status updates.

Overview

This MCP server connects to a running shadow-cljs instance and tracks build progress, failures, and completions. It provides an MCP tool that LLMs can use to verify build status after making changes to ClojureScript files.

LLM Integration

Adding to Your LLM Notes

Add the following to your LLM's notes file (e.g., CLAUDE.md, cursorrules.md):

After any edits to ClojureScript files, use the shadow-cljs-mcp server's get_last_build_status tool to verify the build succeeded:

<use_mcp_tool>
<server_name>shadow-cljs-mcp</server_name>
<tool_name>get_last_build_status</tool_name>
<arguments>
{}
</arguments>
</use_mcp_tool>

This will show:
- Build status (completed/failed)
- Which files were compiled
- Any errors or warnings
- Build duration and metrics

Example Tool Response

{
  "status": "completed",

  "warnings": 0,
  "duration": 0.609,
  "compiledFiles": [
    "path/to/your/file.cljs (505ms)"
  ]
}

  "message": "Build failed",
  "details": {
