The WhenLabs/When server provides a developer toolkit via MCP with six integrated tools:

🕐 Velocity — Task Timing & Performance

• Start/stop timing coding tasks with metadata (category, tags, project, model)

• Estimate multi-step plan durations based on historical data

• Query performance statistics grouped by category, tag, project, or time period

• View task history and generate HTML dashboards with performance charts

📄 Stale — Documentation Drift Detection

• Scan for discrepancies between documentation and code

• Auto-fix issues (wrong file paths, dead links, outdated scripts)

• Generate .stale.yml config for custom detection rules

🔐 Envalid — Environment Variable Validation

• Validate .env files against schemas

• Detect undocumented env vars and scan for leaked secrets

• Generate .env.schema from existing files or code analysis

• Compare .env files, sync multiple env files, and generate safe .env.example templates

• Check/install git hooks for pre-commit validation

🔌 Berth — Port Conflict Management

• Show active ports and diagnose conflicts before starting dev servers

• Kill processes on specific ports or free all ports for a project

• Register projects with port requirements and list their statuses

• Reassign ports in config files and auto-resolve conflicts via kill/reassign strategies

🧠 Aware — AI Context File Generation

• Auto-detect project stack and generate AI context files (CLAUDE.md, .cursorrules, etc.)

• Regenerate context files from .aware.json and show changes since last sync

• Validate configuration, diagnose project health, and auto-sync stale context files

• Add rules, conventions, or structure entries to configuration

⚖️ Vow — License Compliance

• Scan and summarize dependency licenses; validate against policy files

• Generate license policy templates and display dependency trees with license annotations

• Suggest alternative packages for violations and export reports (JSON, CSV, Markdown)

• Install git hooks for pre-commit license checks and generate THIRD_PARTY_LICENSES.md

All tools are accessible through a single MCP server for Claude Code, with per-tool CLI access and unified commands for project onboarding (when init) and health reporting (when doctor).

Validates .env files against schemas, detects undocumented environment variables in codebases, and generates .env.schema files from code analysis.

Provides CI/CD integration with GitHub Actions for running stale, envalid, and vow checks with annotations and machine-readable JSON output.

Installs pre-commit hooks for license validation checks to ensure compliance before commits are made.

Uses SQLite as the embedded database backend for the velocity tool to persistently track coding task timing and performance metrics.

Manages unified project configuration through .whenlabs.yml files that consolidate settings for all six tools in a single YAML configuration.
