For teams shipping AI agents
One runaway agent loop can burn a month of API budget overnight. Cap it before it starts.
Move the sliders to see what runaway loops cost you today and what a per-run circuit breaker would save. LoopBreaker sits between your agents, model APIs and MCP servers.
- Per-run and per-user token caps
- Loop detection on repeated tool calls
- Audit log of every MCP tool call
Runaway-loop cost calculator
Rough numbers are fine — the point is the order of magnitude.
Monthly spend on runaway loops
$720/mo
Runaway loops are a real budget line
- Runaway runs per month
- 300
- Tokens burned by runaway runs (millions)
- 120
- Cost with a 50k-token circuit breaker
- $90
- Saved each month
- $630
- Saved over 12 months
- $7,560
A 50k-token circuit breaker would save about $630 a month on runaway runs alone.
Runaway runs per month = runs per day × 30 × share that loop or stall. Cost uses a blended $6 per million tokens (input + output) — adjust for your model mix. Savings assume a circuit breaker that stops each runaway run at 50k tokens.

What LoopBreaker does for you
Circuit breaker
Stops a run when token use, repeated tool calls or wall-clock time cross your limits.
Hard cost caps
Daily and per-user spend ceilings enforced at the gateway, not in a dashboard after the fact.
MCP gateway
One endpoint in front of your MCP servers with allow-lists and per-tool permissions.
Full audit trail
Every model and tool call logged with cost, latency and the run that triggered it.
Questions, answered
Can I use LoopBreaker today?
LoopBreaker is opening in weekly cohorts. Choosing a plan costs nothing today and no card is taken. You'll get one email when your cohort opens, with a 40% lifetime founding discount applied.
Which providers are supported?
OpenAI-compatible APIs, Anthropic and Google models, plus MCP servers over HTTP at launch.
Do you store my prompts?
Prompt-content logging is optional and off by default. Cost, latency and metadata are always logged so caps can be enforced.
