CarbonMeld MCP server

CarbonMeld's remote MCP server gives AI assistants read-only research on voluntary carbon credit projects: ratings built from the documents registries publish, the registries' own data, and the method behind each rating.

  • Server URL: https://carbonmeld.com/api/v1/mcp (Streamable HTTP)

  • Sign-in: OAuth 2.1 with your CarbonMeld account. You approve the connection on a CarbonMeld page, and you can disconnect an assistant at any time from your account page («Connected assistants»).

  • Read-only: the tools cannot change anything, buy, sell or make a payment.

  • Official MCP Registry: com.carbonmeld/carbonmeld, described by server.json

This repository holds the server's public description only: its registry entry and client examples. The server runs at the URL above; its code is not here.
