MyCO2 Suite MCP server

Which MCP servers are MyCO2 Suite's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry nameio.myco2suite/carbon-intelligenceverified in the MCP registry

The registry name sits under myco2suite.io. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-26 the server answered initialize and tools/list without a sign-in. First answer in 732 ms.

Should an agent connect itNot proven either way yet
  • Its tools do every use case we checked: calculate emissions from spend using industry codes; estimate CBAM liability for imports by CN code.
  • Checked on 3 of the 7 days it takes to judge reliability.

Once connected

  • For "calculate emissions from spend using industry codes", the likely first call is calculate_emissions_transaction.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

None of the five warning signs in these definitions.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

  • calculate_emissions_transaction

    Calculate CO2e emissions for a business transaction (spend-based)

  • calculate_emissions_flight

    Calculate CO2e emissions for a flight

  • calculate_emissions_freight

    Calculate CO2e emissions for freight transport (sea, road, rail, or air cargo). Supports single-leg and multi-leg intermodal journeys. Locations accept UN/LOCODE (e.g. 'GBSOU'), IATA airport code (e.g. 'LHR'), free-text name (e.g…

  • calculate_emissions_activity

    Calculate CO2e emissions for an activity (electricity, fuel combustion, materials, transport, etc.)

  • calculate_emissions_activity_batch

    Calculate CO2e emissions for up to 100 activities in a single request. Each item is resolved in parallel. Items that fail validation or are not found return per-item errors without failing the whole batch.

  • calculate_cbam_liability

    Calculate CBAM (Carbon Border Adjustment Mechanism) embedded emissions and estimated EUR liability for an imported good. Covers Phase 1 sectors: cement, aluminium, iron & steel, fertilisers, hydrogen. Applies the year's phase-in rate…

  • calculate_cbam_batch

    Calculate CBAM liability for up to 100 shipments in one request and return a portfolio-level summary (total embedded tCO2e, total certificates, total EUR liability). Ideal for pricing a whole shipment manifest or product catalogue…

  • lookup_cbam_cn_codes

    Look up / search EU Combined Nomenclature (CN) codes for CBAM. Find the 8-digit code for a product, check whether it is currently subject to CBAM (cbam_phase1=true) and which sector, then pass the cn_code to calculate_cbam_liability.

  • lookup_cbam_carbon_prices

    Look up the carbon price(s) in a country (World Bank Carbon Pricing Dashboard) as an INDICATIVE starting figure for the carbon_price_paid_eur_per_tonne input on calculate_cbam_liability. Returns instrument name, type (ETS/carbon tax)…

  • lookup_emission_factors

    Look up emission factors by classification code (MCC, NAICS, ISIC, SIC, NACE, BEA) or activity type

  • list_activity_types

    List available activity types for emission calculations, optionally filtered by country or category

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "carbon-intelligence": {
      "type": "http",
      "url": "https://api.myco2suite.io/v1/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http myco2suite https://api.myco2suite.io/v1/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://api.myco2suite.io/v1/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
