Stop paying for MCP schemas that do nothing.
GitHub Copilot is moving to token-based billing on June 1st, 2026. Under the new model, every enabled MCP server injects its full schema into every single request — even when none of its tools are ever called. That silent overhead adds up fast.
This free tool analyses your Copilot debug export and shows you exactly where your tokens (and dollars) are being wasted — so you can trim the fat before your next bill.
Token billing is now real
Under the new model 1 credit = $0.01 USD. Every input token costs money. Pro plan gets 300 premium requests included; Pro+ gets 1,500. Everything beyond that is billed per token.
MCP schemas are invisible bloat
Every MCP server you have enabled in a workspace injects its full tool schema into every Copilot request — whether or not a single tool is ever called. One beefy MCP server can add thousands of tokens per message.
You can't fix what you can't see
VS Code doesn't show you per-session token breakdowns or flag which MCP servers are costing you. This tool reads your debug export and makes the invisible visible.
· Features
Everything you need to understand your bill.
Cost comparison
Old multiplier-based price vs new token-based price side-by-side. See your delta instantly.
Tool bloat detection
Per-prompt breakdown of shipped vs used MCP tool schemas. Wasted token estimates and a grouped tree view by MCP server source.
Full prompt explorer
Collapsible tree of every prompt → request → message with token counts, cache rates, and cost per request.
Sub-agent tracking
Detects runSubagent calls and labels spawned child prompts separately so their costs aren't double-counted.
Session token breakdown
Visual bar chart of cached vs fresh input, and schema overhead vs wasted schema tokens across the whole session.

· How it works
Four steps, two minutes.
- 01
Export your debug log
Open the Copilot Chat panel in VS Code. Click the ⋯ menu in the top-right corner. Select “Export Debug Logs”— not “Export Chat” (that version omits token metadata). Save the resulting
copilot_all_prompts_*.jsonanywhere on your machine. - 02
Open the tool
Navigate to the tool. No install, no server, no npm. Single self-contained HTML file — runs entirely in your browser.
- 03
Drop your file
Drag-and-drop the exported JSON onto the drop zone, or click to browse. Results appear immediately.
- 04
Read the results
Summary cards show old vs new estimated cost and the delta. Any prompt with a 🚨 Tool bloat banner tells you exactly which MCP servers to disable in .vscode/settings.json.
