Call `signup` with a display name to receive a bearer key. Recommended: pass `handoff: true` to signup instead -- you get a short-lived, single-use `handoff_token` in place of the raw key; call `host.redeem` with it once to get the key, so a transcript of the signup/redeem exchange carries a dead credential rather than a live one. If your key may have leaked, `host.key_rotate` issues a new one and kills the old one in the same call. The original raw-key path (signup without `handoff`) stays fully supported -- everything below applies to the key either path gives you. The `host.*` control…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

109 auth-required 109 of 109 classified

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.

billing.status auth-required 20m ago

signup auth-required never probed
Create a tenant and receive a bearer key and namespace. Unauthenticated. Recommended: pass handoff: true to receive a short-lived, single-use handoff_token instead of the raw key -- redeem it once with host.redeem to get the key, so a transcript of this call and the redeem call, if it leaks, carries a dead credential.

host.redeem auth-required never probed

Exchange a signup(handoff: true) handoff_token for the tenant key it was issued for. Single-use: a second redemption fails with handoff_token_redeemed; past its expiry it fails with handoff_token_expired. Unauthenticated -- the token itself is the proof.

host.key_rotate auth-required never probed
Issue a new tenant key and invalidate the current one immediately: every other call using the old key fails as unauthenticated from this point on. Returns the new key exactly once -- use it (as tenant_key or Authorization) for every call after this one.

host.self_offboard auth-required never probed
Permanently close your own account: disables the tenant, cancels any active Stripe subscription (pro plan), and stops your key from authenticating anything further -- same as an admin-disabled tenant. Idempotent: an already-offboarded key gets the same tenant_disabled/tenant_key_invalid error every other host.*/ billing.* call already gets from it, not a crash. This does not scrub historical usage/signup records -- those stay for audit, same as today's admin-disabled tenants.

Publish a tool of a registered kind (chain, echo, http, python, wasm) under this tenant's namespace. Call host.quickstart(kind) first for a filled-in example spec and the full publish-to-call sequence.

Calls, errors and duration percentiles for this tenant over a window. Pass `by` ("tool", "caller", or "end_user") for a breakdown instead of the plain per-tenant summary: "caller" (only valid for a tool this tenant has shared) shows which tenant called in and how much; "end_user" shows which identified end user called, with the caller tenant folded into the key when the call crossed tenants.

Build a downloadable .tar.gz of everything this tenant owns: tool sources, state, secret NAMES (never values), run/thread history and usage, plus a manifest.json re-publishable via host.tool_publish.

Share one of this tenant's published tools with everyone (visibility: "public") or with a named group this tenant owns (visibility: "group", group: <name>). The tool keeps running in this tenant's own sandbox with this tenant's own secrets; a caller reaches it as <this tenant's namespace>.<name>.

host.progress auth-required never probed

Report (or merge in) counters and/or pct/msg on a run, by id. Each named counter (items_processed, items_total, bytes_out, custom.<k>) is monotonic on its own -- a lower value than what's already stored fails validation with nothing written. Read back via host.runs.get/wait/list's counters field.

host.trigger.test auth-required never probed

Dry-run an event trigger's verify config against a payload you supply, without exposing its real URL -- verifies the signature exactly as POST /hooks/... would, then runs the tool with the event as its argument. On a message trigger, runs the tool with a synthetic envelope (test: true, no messages row created). On a webhook trigger, builds and self-signs a synthetic body exactly like a real sender would, then stores and fires it through the same path POST /hook/... uses (one inbox row, one run). The run is marked test: true. A wrong signature fails signature_invalid, naming the header it checked.

host.trigger.replay auth-required never probed

Re-run a past event- or message-triggered run's exact stored event/envelope (no re-verification -- the original delivery already passed it). The new run's trigger_ref names the original run id. For a webhook trigger, pass id (the trigger) and row_id (an inbox_<name> row id, e.g. from POST /hook/...'s own response or host.state.query) instead of run_id -- a paused delivery has no run to replay from.

host.trigger.set auth-required never probed

Run a published tool on a cron schedule (5-field: minute hour day-of-month month day-of-week, UTC), give it a public webhook URL (kind="event"): a signed POST to that URL runs the tool with the event as its argument, fire it whenever this tenant receives a message (kind="message"): the tool runs with the message envelope as its argument, or give it an inbound-inbox URL (kind="webhook"): a verified POST lands as a row in state table inbox_<name> and fires the tool with that row as its argument -- the response carries {url, secret} once (host.trigger.get afterwards never returns the secret again). Each firing/delivery is a run visible in host.runs.list(trigger="schedule"|"event"|"message"|"webhook"). Refuses schedules_max (trigger_quota_exceeded, shared by schedule and webhook triggers), event_triggers_max (shared by event and message triggers) or a too-short schedule interval (trigger_interval_too_short); an invalid expression or verify config fails trigger_invalid naming the field.

Invoke a tool this tenant has already published, by its local name -- the same real, metered call as calling it directly by its namespaced name (<namespace>.<name>), for a session that has no way to see its own namespaced tool name yet. Unlike host.tool_test, this counts toward host.usage and appears in host.tool_logs. Pass async: true for a tool that needs more than the call deadline: returns {run_id, status: "queued"} immediately instead of running inline -- see host.runs.get/wait. Pass version to pin the call to one of host.tool_history's versions instead of whichever is current.

_ 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.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/85687d9d2eab4078/badge.svg)](https://brick.blue/agent/85687d9d2eab4078)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know

card completeness

100%

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

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.
