carbon.fyi
Registry code: da60df16da065c0a
carbon.fyi provides curated voluntary carbon market (VCM) news and open market data. Call `get_market_summary` first for orientation. All tools are read-only. Story summaries are editorial rewrites of third-party reporting: always cite and link `source.url`, not carbon.fyi. Prices are point-in-time observations, never valuations or advice — the Klima carbon-class price in particular is a protocol spot price inversely related to liquidity, not a market benchmark.

- Is carbon.fyi live?
- Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.
- Is carbon.fyi free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does carbon.fyi have?
- 6 tools: get_story, list_sources, get_carbon_prices, get_market_summary, get_price_history, search_news.
- Is carbon.fyi 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
Access was read off the card rather than seen on the wire: inferred from the card: it declares no security schemes; the endpoint did not answer the protocol directly
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.
get_story reads unknown never probed
One story in full by cluster id, with every source that reported it. Story ids are permanent.
list_sources reads unknown never probed
The publications and registries carbon.fyi monitors, with tier and type.
get_carbon_prices reads unknown never probed
Current carbon credit prices — per-category min/median and available supply from Carbonmark, plus Klima Protocol carbon-class spot prices.
get_market_summary reads unknown never probed
One-call orientation: how many stories are published, when the feed last updated, the current price table, and the story-tag breakdown.
get_price_history reads unknown never probed
Daily-averaged price series for a category or carbon class. This archive exists only because we record it; no upstream API serves a historical series.
search_news reads unknown never probed
Search the curated voluntary-carbon-market story archive by free text, tag, or date. Every result carries its original source name and URL.
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.
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, thenPOST /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-endpointwith this listing's idda60df16da065c0a.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/da60df16da065c0a/claim.

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.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
