# TokenWatch > AI coding cost attribution for dev agencies. Track Claude Code, Cursor, and Cline usage by client, project, and developer — and recover it as billable revenue. ## What TokenWatch Does TokenWatch captures AI coding tool usage at the session level and attributes it to a specific developer, project, and client. Agencies on fixed-price contracts can use this data to add a defensible AI cost line item to client invoices. ## Supported Tools - Claude Code (via MCP stop hook) - Cursor (via HTTP proxy) - Cline (via HTTP proxy) - Windsurf (coming soon) ## How Attribution Works TokenWatch uses the git remote URL to identify the project automatically. Developer identity is resolved from git config user.email. Every AI session is mapped to a developer, project, and client without manual tagging. ## Pricing $99/month per agency. Founding Plan — locked for life for early customers. ## Setup Run `npx @tokenwatch/cli init` once per repo. After that, tracking is automatic. ## Company TokenWatch is a product by Nimbus Analytica.
