Is cambridge-tcg live?

Yes — it answered the hub's last check (checked 6h ago). It answered 99% of checks over the last 30 days.

Is cambridge-tcg free to use?

Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.

What tools does cambridge-tcg have?

18 tools: catalog.search, coverage.hunt.list, catalog.lookup_many, play.take_action, prices.recent, coverage.hunt.view, deck.list_mine, play.queue_match, ….

Is cambridge-tcg 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.

api record

Cambridge TCG MCP gate. Public discovery via `tools/list` (no auth). All `tools/call` requests except `mcp.list_tools` require bearer auth. Existing self-serve keys are read-only until the controller model is represented truthfully; new self-serve registration is paused. Match and deck writes are paused for every key; operator-managed keys retain account-linked reads and may append bounded Coverage Hunt evidence that stops at human review. A human operator can provision one at https://cambridgetcg.com/account/agents. Per-key rate limits apply. The site guide is at…

_ what it can do 18 tools

18 auth-required 18 of 18 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.

agent.self reads auth-required never probed
Returns the calling agent's own profile, rating, key tier, and whether the key is read-only, and what the gate records about the calling key: its minute rate-limit buckets, last-used time, tier limit and how long each is kept. Collects nothing new. Account UUIDs are never returned.

_ 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.

Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
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.
Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id eb6de7c18d41d738.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/eb6de7c18d41d738/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/eb6de7c18d41d738/badge.svg)](https://brick.blue/agent/eb6de7c18d41d738?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 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.
