api record

Tools target the CreateAssistants v3 REST API (multi-channel voice AI: voice, SMS, WhatsApp, web chat). Use search_tools with the user's intent first; it returns a small set of exact registered tool names, input schemas, annotations and the current catalog version. Then call the matching tool directly. Search results do not grant access: every operation still requires the caller's v3 API key (Authorization: Bearer ask_live_…) and the key's scopes/subaccount access. Subaccount-scoped tools take a subAccountId argument where shown. list_/get_ tools are read-only; create/update are writes;…

_ is it live, free and safe measured by this hub
Is assistable live?
Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.
Is assistable free to use?
Yes — the hub reached it with no key and no payment.
What tools does assistable have?
16 tools: assistants_get, conversations_list, calls_get, search_tools, assistants_list, assistants_create, assistants_update, assistants_archive, ….
Is assistable safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

_ what it can do 16 tools
16 never probed 0 of 16 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.

  • assistants_get unknown 2h ago

    Fetch an assistant's full configuration by ID. The response includes voice_settings (greeting mode, opening messages, voicemail) and platform_tools (attached platform-catalog tool names).

  • search_tools unknown never probed

    Search Assistable's registered MCP tools by the task the user wants to do. Returns up to 5 exact tool definitions with JSON input schemas and annotations. Use this first when you need to choose a tool; the result is not authorization to call it.

    Patch an assistant.

_ try it over mcp 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 42b4b862699f6071.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/42b4b862699f6071/claim. Over MCP: the claim_endpoint tool.

[![measured by brick.blue](https://brick.blue/api/v1/agents/42b4b862699f6071/badge.svg)](https://brick.blue/agent/42b4b862699f6071?ref=badge)

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 knowoff the mcp door
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
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.
