Costlens — Ai Productivity Tracking is an MCP server that measures what AI code agents actually ship. It provides automatic session tracking, event logging, cost tracking per session and deliverable, GitHub PR metrics, and productivity reports with ROI calculation. It is designed for developers and teams using AI coding agents to quantify output and cost efficiency.
Run npx @costlens/mcp-server setup – one command opens a browser for authentication and auto‑configures your agent. After setup, the server exposes seven tools: start_session, end_session, log_event, get_productivity_summary, get_spend_summary, get_github_metrics, and costlens_suggest_model. All tracking is async and never blocks your workflow.
