mcp-tax billing model updated to per-turn schema cost calculation

By PulseAugur Editorial · [1 sources] ·

The mcp-tax billing model has been updated to version 0.3, correcting a previous undercounting of schema costs. The new model now bills schema re-entry into the context window on a per-turn basis, rather than once per session, reflecting the actual token usage for each API call. This update also separates billing into independent lines for each server, accounting for preamble tokens, cumulative window tokens, and billable tokens distinctly. Additionally, a new per-page wire counter has been introduced to track transport costs for discovery separately from context tax. AI

IMPACT This update refines cost accounting for AI model interactions, potentially impacting developers' budget management for token usage.

    mcp-tax 0.3: your MCP schemas are billed every turn, not once per session

    <p>Two readers argued with my billing model in the comments, and they were right. So mcp-tax 0.3 rebuilds it.</p> <h2> The correction: schemas re-enter the window on every turn </h2> <p>The old <code>audit</code> billed each server's tool schemas once per session. That's wrong — …
