Moven sits directly in-process, intercepting runaway tool recursion in <0.8ms, enforcing hard dollar ceilings, and auto-generating AST self-healing PRs before your credit card is charged.
In plain English: If your AI agent gets trapped in a recursive tool loop, Moven cuts execution in <0.8ms before costs explode, rewinds memory safely, and opens a bugfix PR.
Scroll to trace one turn live from in-process bytecode interception to automated pull request synthesis.
Follow one agent turn down the signal path.
It is 02:41 in the morning. Nobody is watching. Your agents are still working and somewhere in the stack, this turn is about to go wrong. This is not a basic circuit breaker. Moven runs canonical hashing, entropy delta analysis, and AST-level state management inside your process. Scroll to trace it.
Stations 01-05 are the defense. This is the payoff: your fleet runs at full speed with hard budget fuses on every turn, without human babysitting.
TRIP IT YOURSELF — LIVE SANDBOX BELOWA simulated agent turn, replayed with real breaker logic. Press run and watch a runaway loop get intercepted before it spends a cent.
What you are watching: three identical tool calls produce three identical canonical hashes. No LLM guessing, no proxy, no cloud — deterministic math trips the fuse in 0.42ms.
THIS SANDBOX RUNS THE REAL BREAKER LOGIC IN YOUR BROWSER. NOTHING LEAVES THIS PAGE.
Zero proxy configuration. Runs locally in your agent thread with sub-millisecond execution. Edit the fuses and watch the snippet follow.
One package. No sidecar, no proxy container, no background worker to babysit.
Set the hard fuses — repeat ceiling, dollar ceiling, auto-heal. Use the LIVE CONFIG bar on the snippet: it edits the real code.
One decorator — or one wrapTools() call — around any function or agent step. Every call now passes a fuse.
Estimate loop protection savings based on your active agent fleet volume.
* Assumptions & Methodology:Model calculates estimated savings based on an unmitigated recursive loop consuming ~340 iterations ($19.50 baseline per runaway turn across GPT-4o / Claude 3.5 Sonnet token budgets) before manual discovery. Moven trips in <0.8ms (at ~1.5 iterations), preserving >92% of compute budget.
Actual savings vary by LLM provider pricing, tool execution latency, and per-token quota policies.
APM tools observe failures after your bill explodes. Moven intercepts and heals in real time.
Moven SentinelDeployed by AI infrastructure teams shipping mission-critical autonomous agents.
“Moven completely eliminated our runaway tool loops. When our autonomous billing agents got stuck querying the same customer endpoints, Moven's sentinel tripped in 0.42ms and rolled back in-memory AST state before our Stripe account was hit with a 4-figure charge.”
— Preetham Rangu, Co-Founder & CEO at Everfern AI
“Before Moven, an unconstrained sub-agent loop could burn hundreds of dollars overnight while hallucinating duplicate parameters. Having in-memory hard budget ceilings and instant breaker trips gave our team the confidence to scale autonomous workflows to thousands of users.”
— Aaron Allam, VP of Engineering at ProSite Technologies
“The zero-proxy in-process sentinel is brilliant. We plugged Moven directly into our LangGraph supervisor with 3 lines of code. It stops zero-entropy hallucination loops in microseconds without adding a single millisecond of network latency.”
— Devarsh Patel, Founding AI Engineer at NexusOps
