CarbonGuru MCP server

CarbonGuru is the official remote MCP server from carbonguru.io. It answers at https://carbonguru.io/mcp over streamable HTTP and asks you to sign in with your carbonguru.io account before it lists its tools, so your client opens a login the first time it connects. Our probes reached it 6 of 6 times since 10 September 2026; the last check, on 19 October 2026, got the sign-in challenge, so it is up.

Carbon footprints for products, carts, receipts and files — with one-step offsetting.

Description as the publisher wrote it.

What CarbonGuru needs before it works

A sign-in. The server refused to list its tools to an anonymous client and answered with an authentication challenge, which is how an MCP server protected by OAuth behaves. Add it with one of the setups below; the first connection opens a login for your carbonguru.io account, and the tools appear once you have approved it.
