What your AI can do with Carbon Fyi
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “search_news”: Search carbon.fyi's curated voluntary carbon market story archive. Each story is an editorially clustered summary of one development, writte.”
“Use “get_story”: Fetch a single story by its id, including every source that reported it. Story ids are permanent — a published story keeps its id and its pu.”
“Use “get_carbon_prices”: Current voluntary carbon credit prices from two independent sources: per-category minimum/median price and available supply across the Carbo.”
“Use “get_price_history”: Daily-averaged historical price series. This archive exists only because carbon.fyi records it three times a day: no upstream API serves a h.”
How secure is the Carbon Fyi MCP server?
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Carbon Fyi holds up.
Official endpoint
Operated by Carbon Fyi (carbon.fyi) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If Carbon Fyi adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

https://www.carbon.fyi/api/mcpQuestions, answered
Is there an official Carbon Fyi MCP server?
Yes — Carbon Fyi operates its own remote MCP server at www.carbon.fyi. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect Carbon Fyi to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick Carbon Fyi in the directory. No account or sign-in is needed. From then on, Carbon Fyi's tools are available in every client you've connected to gate.
Do I need to host anything?
No. Carbon Fyi runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the Carbon Fyi MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
