api record

Idle-sandbox guard for AI agents. Your agent sends its running E2B, Vercel Sandbox, Daytona or Modal sessions; Sandbox Timer flags the idle ones, shows what idle time cost at the hourly rates you give it, and with Pro at $9 a month returns the ready-to-run kill call for each. A guard on top of your sandboxes, not a sandbox. It never holds your provider keys. Free 500 calls/day, then $9/month. No model inside: bring your own model. Works with Claude, Codex, ChatGPT, Grok Bot.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • track_sessions unknown never probed

    Send 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-to-run kill call per idle sandbox for its provider (E2B kill, Vercel Sandbox stop, Daytona stop, Modal terminate) and POSTs one alert per sandbox to your webhook. Free watch-only returns would_kill and sends nothing. We never hold provider keys and never kill anything ourselves: your agent runs the call with its own key.

  • idle_report unknown never probed

    Which 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_rules unknown never probed

    Pro: 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_report unknown never probed

    Plain-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.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id d02d7d6f59851c1e.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/d02d7d6f59851c1e/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
90%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
