Tallyhook Collector

Tallyhook Collector is a command-line tool that calculates and tracks the costs of AI coding agents per repository and client.

Tallyhook Collector calculates what AI coding agents cost by reading local session logs from Claude Code and Codex CLI. It runs entirely on your machine without requiring an account or uploading data, processing logs to price usage based on public vendor rates. The tool groups costs by repository, model, or client, and helps map expenses to client invoices. It also includes an MCP server so coding agents can answer questions about their own resource consumption directly. Designed for developers who bill clients for AI-assisted work, it ensures accurate pricing by deduplicating streamed rows, handling subagents, and accounting for cache tiers. Optional features also allow syncing data to a hosted layer for team-wide tracking and client report links.
