See what your AI coding agent actually sends to the API — and what each part costs.

agents capture local only license MIT

Most usage tools read local logs. That shows the total cost of a call or session, but it misses the request-time context assembled before the model is invoked: system prompts, tool schemas, MCP blocks, tool results, cache reads/writes, and previous thinking blocks.

cost-xray captures the actual local API traffic for Claude Code and Codex, then attributes tokens and dollars back to the sources inside the request. It shows not just how much a turn cost, but why it cost that much.

Home — every session by agent · project · session, with token and dollar totals
cost-xray Home: every captured session grouped by agent · project · session, with per-row turns, cache-hit %, tokens, and cost
Drill a session — context-window occupancy (top) and per-source cost, down to each MCP server (bottom)
cost-xray Detail: context-window occupancy this turn (top) and cumulative per-source cost drilled down to each MCP server (bottom)
