Voluntary carbon market news and open carbon price data. Read-only, keyless.
Read-only, keyless access to carbon.fyi's curated voluntary carbon market news archive and open carbon price data.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/fyi.carbon%2Fcarbon-fyi/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

Search VCM 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 least one filter; results are newest-first. Use `get_market_summary` first if you do not know what tags or date range to ask for.
taglimitquerysinceGet one 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.
idrequiredCurrent carbon prices
Current voluntary carbon credit prices from two independent sources: per-category minimum/median price and available supply across the Carbonmark marketplace catalog, and spot prices per Klima Protocol carbon class. The two are NOT comparable — read the `caveats` field on each before using either number.
Takes no parameters.
Carbon 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 re-derived. Check `seriesStartsAt` in the response — the archive began on 2026-08-27, so early windows are necessarily short.
keydayskindrequiredMarket 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.
Takes no parameters.
Monitored 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.
Takes no parameters.
75% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
Declare a GitHub repository with a README, or serve resource_documentation in the OAuth protected-resource metadata.
Declare a license in the repository or the registry entry.
