Connect EcoCheck to Claude and ChatGPT via MCP

Since October 2026, EcoCheck supports MCP (Model Context Protocol), the open standard that lets AI assistants such as Claude and ChatGPT connect directly to business software. You can ask an AI “Does my factory have to conduct a greenhouse gas inventory in 2026?” or “What were our company’s total Scope 1 and 2 emissions in 2025?” and get an answer pulled straight from EcoCheck, with sources cited, instead of from the AI model’s generic memory. Access to your company data always requires you to sign in and give consent; writing is possible only when you and the workspace owner allow it.

Update 8 Oct 2026: the business account connection now also supports writing data (record activity data, create sources, build CBAM data) when you choose read and write and the workspace owner allows it. The figures below show the read-only version of 6 Oct. See the latest guide to using EcoCheck inside ChatGPT and Claude.

What is MCP and why does EcoCheck support it?

MCP is an open protocol that lets AI assistants call a piece of software’s “tools” in a standardized way, much like a USB port for AI. Instead of copying figures from EcoCheck into a chat window, the AI calls EcoCheck’s tools itself to fetch exactly the numbers it needs. Key benefits:

• Figures from the right source: answers are based on the inventory data and regulations EcoCheck is using, not outdated information memorized by the AI model.
• Time savings: ask in plain language and the AI finds the right workspace, inventory period and report on its own.
• Works in the tools you already use: Claude, ChatGPT and other MCP-compatible applications.

What does EcoCheck offer AI agents?

There are two access levels serving two different needs:

Some representative tools:

• check_ghg_inventory_obligation: checks whether a facility is subject to mandatory inventory under the thresholds of 3,000 tCO₂e / 1,000 TOE / 65,000 tonnes of waste (Decree 06/2022/ND-CP as amended by Decree 119/2025) and the list in Decision 42/2026/QD-TTg.
• get_ghg_regulations: verified 2026 legal milestones (31 March 2027 submission deadline, pilot emission allowances, CBAM 2027).
• get_inventories, get_emissions_report: read your company’s inventory periods and total emissions by Scope, source, facility and gas type.

How do I connect EcoCheck to Claude or ChatGPT?

In an MCP-compatible AI app, add a custom connector (MCP server) and paste the corresponding endpoint:

1. In Claude, EcoCheck is in the Claude Connectors directory: search "EcoCheck" and click Connect. In ChatGPT (the EcoCheck app is still under OpenAI review for the directory): ChatGPT desktop app: Settings › Plugins › Add › Add MCP server (Name EcoCheck, Type Streamable HTTP, URL https://ecocheck.ai/mcp/account) › Save, then sign in to EcoCheck; or ChatGPT on the web: Settings › Apps › Advanced settings › turn on Developer mode › Create (OAuth authentication). In other apps, open the connector / MCP settings and add a custom connector.
2. Enter https://ecocheck.ai/mcp for public information, or https://ecocheck.ai/mcp/account to connect your company data.
3. For the account connector, the AI app will open the EcoCheck sign-in page (in ChatGPT, the “Connect EcoCheck to chatgpt.com” page; choose Continue to sign in). Sign in with your EcoCheck account and approve ecocheck/read (read only) or also ecocheck/write (read and write).
4. Try asking: “List my company’s inventory periods on EcoCheck” or “What were total emissions in 2025 by Scope?”.

The AI app registers the connection itself via the OAuth standard; you don’t need to create an API key or share your password with the AI. Technical details for developers are available at ecocheck.ai/auth.md and ecocheck.ai/llms.txt.

Is my company’s data safe?

EcoCheck designed its AI connection on the principle of least privilege:

• Your company decides: by default the AI can only read. It can write only when the user connects with read and write and the workspace owner sets View and edit or higher; deleting always needs confirmation.
• Your permissions only: the AI uses your own login session, so it sees only the organizations and inventory periods you have been granted access to, nothing more.
• Time-limited and revocable: access sessions expire after 60 minutes, and you can disconnect the connector at any time in the AI app.
• Rate limits and audit logs: each user is subject to query rate limits, and every AI query is recorded in an audit log.

Note: your questions and the answers are processed by the AI provider you choose, under that provider’s data policy. For sensitive data, use an enterprise AI plan that commits to not using your data for training.

How useful are AI agents for greenhouse gas inventory work?

• Faster report preparation: summarize total emissions by Scope, compare across years and pinpoint the largest emission sources.
• Answering internal questions: when leadership asks “Are emissions up or down this year?”, the AI answers with inventoried figures.
• Tracking legal obligations: ask about the 31 March 2027 reporting deadline, CBAM 2027 or emission allowances, with links to the reference documents.

Keep in mind that AI does not replace the inventory and verification process: the figures are only correct when the input activity data is collected and calculated using the right methodology. See our guide to the 2026 greenhouse gas inventory process or EcoCheck’s end-to-end inventory service.

Frequently asked questions

Do I have to pay extra to use the AI connection?

No. The public MCP is free for everyone; the account MCP uses your company’s existing EcoCheck account. Charges for using the AI app (Claude, ChatGPT) are billed by that provider.

Can the AI enter data or edit reports for me?

Yes, since 8 Oct 2026: the AI can record data, correct entries, create emission sources, build CBAM data and export reports if you connect with read and write and the workspace owner allows it. See the detailed guide.

What can I use without an EcoCheck account?

You can still use the public MCP to check inventory obligations, look up 2026 regulations and read articles. To connect your company data, contact EcoCheck to get an account.

How do I disconnect the AI from EcoCheck?

Remove or disconnect the EcoCheck connector in the AI app. Access sessions also expire automatically; to block access immediately, sign out of EcoCheck.

Which apps support MCP connections?

AI assistants and tools that support the MCP standard with remote MCP servers over HTTP, such as Claude and ChatGPT on plans that include custom connectors. Exact features depend on each provider’s service plan.
