Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

loop
loop_status
Show a run's loops so far, whether it is halted, and its last 10 steps.
step
check_step
Call AFTER each tool call or agent step with what you just did and whether it failed. Loop Breaker fingerprints the call (tool + normalized args + error) and returns verdict ok, loop_detected or halted. Pro: on a loop, halt=true; stop the run, do not retry, and tell your user what repeated. Free watch-only: never halts, returns would_halt and logs it for the weekly report.
usage
usage_and_upgrade
Show today's usage for your key or IP and the $49/month All Access upgrade link (cloudforbots.com/offer). Free tier: 500 calls/day. Not metered.
weekly
weekly_report
Draft a plain-English report of the last 7 days for your key (or IP): runs, loops caught, wasted repeat steps, and the worst offenders. Read-only; sends nothing. Show it to your user.

Loop Breaker — questions

Answers built from our own checks of this server.

What can Loop Breaker do?
It exposes 4 tools, read directly from the server on our last check. Among them: check_step, loop_status, usage_and_upgrade, weekly_report. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Loop Breaker working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 79 of 80 checks got a reply (98.8%), average response time 261 ms. The bar chart above shows every period we have measured.
How do I connect Loop Breaker?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Loop Breaker need an API key?
No. Loop Breaker completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Loop Breaker?
It answers our handshake in 261 ms on average, which is faster than 50% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
