What's Wrong?

Environment: Claude Code desktop app (Windows 11), Sonnet 5 for most of the session, switched to Opus 5 at the end. Custom MCP bridge to Autodesk Revit 2026 (IronPython code execution tool).

What happened: One working session (a few hours) editing a roof element in a Revit model — roughly 80 MCP tool calls, several read-only geometry checks per edit, two full rebuilds of one element. By Tuesday afternoon the weekly limit shows ~30% used. Nothing exotic: no web browsing, no large repo indexing, one ~800-line script read once.

Why this matters: Agentic CAD/BIM work is inherently call-heavy: every edit needs a verification round-trip through the API, and tool results (element lists, coordinates) are the actual working data, not noise. With the reduced weekly limits this workflow burns through a week's budget in ~2 days, which makes the product unusable for its best use case.

Acknowledged on our side: part of the burn was avoidable (verbose list dumps, repeated queries). We've since added a helper prelude and stricter output rules. Even so, the remaining necessary volume does not fit the current weekly cap.

What Should Happen?

Reconsider the weekly cap reduction, or
Don't count (or discount) tool-result tokens from local MCP servers the same as generated output, or
Expose a per-session token meter in the app so users can see the burn rate before the weekly warning.
