One Claude Code MCP call fans out to paid workers while a shared cost capability blocks work beyond the 25 dollar limit

One Claude Code MCP call spent the whole agent budget

The Claude Code run had a $25 limit and made one MCP call. Hidden fan-out behind the server produced a $286.40 bill.

Three Claude Code subagents request reservations from one parent-owned budget ledger, which admits two calls and blocks the third before the shared ceiling is exceeded

Claude Code stayed under every child budget and still overspent

Three Claude Code subagents each stayed inside their local limit. Together they broke the run budget because nobody reserved spend at the parent boundary.

A Claude Code cost envelope that prices tool calls before execution, reserves budget at dispatch, records actual spend, and stops over-budget paths

Make Claude Code price the tool path before it starts

Token limits miss the expensive part of many Claude Code runs. A cost envelope prices search, MCP calls, evals, and retries before the agent can spend them.

Claude Code cost loops start as helpful retrying

Claude Code can waste more than tokens when it keeps retrying a weak task. Production teams need budgets, stop rules, and evidence before another agent attempt is allowed.
