How to connect

How to connect carbon-factor-matcher to Claude

The server address to paste into Claude settings:

https://carbon-factor-matcher--nikeandocean.run.tools

  1. Open Claude (claude.ai or the desktop app).
  2. Go to Settings → Connectors.
  3. Click Add custom connector.
  4. Paste the server address copied below into Remote MCP server URL and click Add.
  5. In a chat, click + → Connectors and switch the new connector on.

Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

Authorization

After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

How to connect carbon-factor-matcher to ChatGPT

The server address to paste into ChatGPT settings:

https://carbon-factor-matcher--nikeandocean.run.tools

  1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
  2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
  3. Open Settings → Connectors and click Create.
  4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
  5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
  6. In a new chat open + → Apps/Connectors and enable the connector.

OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

Authorization

On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

How to connect carbon-factor-matcher to Cursor

The server address to paste into Cursor settings:

https://carbon-factor-matcher--nikeandocean.run.tools

Fastest: click Open in Cursor below and confirm the prompt.

Manually:

  1. In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
  2. Paste the JSON copied below into ~/.cursor/mcp.json (per project: .cursor/mcp.json in the repo root).
  3. Save the file. The server appears in the MCP list; authorize it there if asked.

Authorization

If the service needs sign-in, an authorize button appears next to the server in the MCP list.

factor_matchIntelligent emission factor matching for carbon accounting and Life Cycle Assessment (LCA). Takes a natural-language description of an industrial activity or material (e.g. '10kV industrial electricity in Guangdong, 2024' or 'polyethylene production') and returns the best-matching emission factor with CO2-equivalent intensity, confidence score, and reasoning. Free tier uses keyword search over ELCD database (~600 European factors). Pro tier adds embedding-based semantic search + LLM fine-ranking over ecoinvent (~21,000 global factors) with 5-dimension data quality assessment.
factor_searchKeyword search over emission factor databases. Returns matching factors with metadata including emission value (kgCO2e per unit), unit, geographic scope, source database, and publication year. Use this tool to browse available factors by material name, industry sector, or process type. Supports optional category filtering (e.g. 'electricity', 'fuel', 'transport', 'chemicals'). Free tier searches ELCD only; Pro tier searches all databases.
factor_detailRetrieve full metadata for a specific emission factor by its unique identifier. Returns complete information including emission intensity value, unit, geographic scope, applicability conditions, data source, publication year, and (for Pro tier) 5-dimension data quality ratings covering technology representativeness, source reliability, geographic representativeness, time representativeness, and factor type.
