Tool names and descriptions exactly as the server reported them on Nov 13, 2026. The maker wrote them, not us; we show them as plain text.
track_sessionsSend your agent's running sandbox sessions (up to 200; call it on a heartbeat, e.g. every 5 minutes) and get back which are idle past your threshold or over their max lifetime, the dollars idle time has cost at the hourly rates you pass, and what to do. Pro acts: returns a ready-
idle_reportWhich sandboxes were flagged idle and what idle time cost, per provider, from what track_sessions has seen. Without an API key pass fleet. With a key: every fleet on it. Free shows 7 days, Pro 30.
set_idle_rulesPro: save the rules track_sessions applies to a fleet: idle_minutes threshold, max_lifetime_minutes, default rates_per_hour by provider, and alert_webhook. Free returns a preview of the rules and saves nothing (pass the same values on each track_sessions call instead).
weekly_reportPlain-English summary of the last 7 days: sandboxes watched, how many sat idle, dollars idle time cost at your rates, kill calls returned (Pro) or that would have been (free). Read-only; sends nothing. Needs a free API key.
usage_and_upgradeShow today's usage for your key or IP and the $9/month upgrade link. Free tier: 500 calls/day. Not metered.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 28 days ago.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).
