Connect Carbon Fyi and your agent gets 6 tools, among them get_carbon_prices, get_market_summary, get_price_history. It answers at https://www.carbon.fyi/api/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 10 September 2026; the last check, on 19 October 2026, succeeded.
Voluntary carbon market news and open carbon price data. Read-only, keyless.
Description as the publisher wrote it.
| Tool | What it does |

get_market_summary | One call for orientation: how much of the archive is available, when it last updated, the story-tag breakdown (use these as `tag` values for search_news), and the current price table. Start here. |
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 historical carbon price series, so these observations cannot be obtained anywhere else and cannot be Inputs: kind, key, days |
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 public URL indefinitely — so they are safe to store. Inputs: id |
list_sources | The publications, registries and integrity bodies carbon.fyi monitors. Useful for judging coverage — a topic absent from the archive may simply not be covered by these sources. |
search_news | Search carbon.fyi's curated voluntary carbon market story archive. Each story is an editorially clustered summary of one development, written from one or more original reports, and always carries the original source name and URL. Supply at Inputs: query, tag, since, limit |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://www.carbon.fyi/api/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
