Security scores are indicators to help you make informed decisions, not guarantees. Always review permissions before connecting any MCP server.
This plugin requests these system permissions. Most are normal for its category.
Add this to your MCP configuration file:
{
"mcpServers": {
"io-github-whenlabs-org-when": {
"args": [
"-y",
"@whenlabs/when"
],
"command": "npx"
}
}

Six tools. One install.
A single installable toolkit that brings six WhenLabs developer tools into your Claude Code workflow. After install, the tools are exposed over a single MCP server and Claude calls them automatically when relevant.
npx @whenlabs/when install
One-time setup. The installer:
whenlabs) in your Claude Code configurationvelocity-mcp registration (velocity is now bundled)| Tool | Purpose |
|---|---|
| aware | Auto-detect stack and generate AI context files (CLAUDE.md, .cursorrules, …) |
| berth | Detect port conflicts before starting dev servers |
| envalid | Validate .env files against a schema |
| stale | Detect documentation drift between docs and code |
| vow | Scan dependency licenses and validate against policy |
| velocity | Time coding tasks and learn from historical data |
Eight endpoints across the six tools:
| Endpoint | What it does |
|---|---|
aware_sync | Detect stack and regenerate AI context files |
berth_check | Scan project for port conflicts |
envalid_validate | Validate .env files against schema |
stale_scan | Detect documentation drift |
vow_scan | Scan licenses and validate against policy |
velocity_start_task | Start timing a coding task |
velocity_end_task | End timing and record results |
whenlabs_summary | Unified rollup across all five scanners in one call |
All eight are served by the single whenlabs MCP server (stdio, Node 20+). Fix/init/auxiliary commands remain available via each tool's CLI (npx @whenlabs/<tool> --help).
when init # Onboard a project — detect stack, bootstrap configs, run all checks
when doctor # Run all six tools and show a unified health report
when install # Register MCP server in Claude Code
when uninstall # Remove MCP server
For per-tool operations, use the tool directly:
npx @whenlabs/stale scan
npx @whenlabs/envalid validate
npx @whenlabs/berth check
npx @whenlabs/aware sync
npx @whenlabs/vow scan
If you're not using the install command, add this to your Claude Code MCP config:
{
"mcpServers": {
"whenlabs": {
"command": "npx",
"args": ["@whenlabs/when", "when-mcp"]
}
}
}
