The source catalog does not include a structured feature list. Review the repository documentation before use.
SECURITY
An MCP listing is not a security review
An MCP server may receive model context, credentials, local files, or permission to call external systems. Review its code, requested environment variables, network behavior, package provenance, and maintenance status before connecting it to an agent.
README
Repository documentation
A Model Context Protocol (MCP) server that monitors shadow-cljs builds and provides real-time build status updates.
Add the following to your Cline/Cursor/Claude whatever settings:
{
"mcpServers": {
"shadow-cljs-mcp": {
"command": "npx",
"args": [
"shadow-cljs-mcp"
],
"disabled": false,
"autoApprove": [],
"timeout": 60
}
}
}With optional server location
{
"mcpServers": {
"shadow-cljs-mcp": {
"command": "npx",
"args": [
"shadow-cljs-mcp",
"--host",
"localhost",
"--port",
"9630"
],
"disabled": false,
"autoApprove": [],
"timeout": 60
}
}
}The --host and --port arguments are optional. If not provided, the server will default to connecting to localhost:9630.
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.
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 metricsSuccessful build:
{
"status": "completed",
"resources": 317,
"compiled": 1,
"warnings": 0,
"duration": 0.609,
"compiledFiles": [
"path/to/your/file.cljs (505ms)"
]
}Failed build:
{
"status": "failed",
"message": "Build failed",
"details": {
// Error information
}
}- LLMs should call get_last_build_status after each ClojureScript file edit
- Compilation errors will be shown in detail for easy debugging
- Successful builds show which files were compiled and how long they took
- Make sure shadow-cljs is running before starting this server
- Running shadow-cljs instance (defaults to localhost:9630 if not configured otherwise)
