Read companies, relations and installations; create companies and relations in Climatools. For refrigeration and climate installers who keep customer records in Climatools. Hosted by usefulapi — connect from Claude, ChatGPT, Cursor, or any MCP client.
Team and Enterprise: an Owner adds the connector for the organization first.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"climatools": {
"url": "https://climatools.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {

}
}
}No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run these commands. The second one opens the login page:
Other MCP clients (Windsurf, Cline, Zed and more): add the URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser. Do not add an Authorization header: see Before you connect.
Search the companies by name or client number. Open one company to read its address and tags.
climatools_list_companies climatools_get_company
Search the private contacts by e-mail, name or client number. Open one contact to read its address and tags.
climatools_list_relations climatools_get_relation
List the installations with their brand, model and refrigerant circuits. Look up the refrigerants that Climatools knows.
climatools_list_installations climatools_list_refrigerants
Search for the company first to avoid a duplicate. Then create the company with its name and address.

The login page asks for your Climatools API key.
Create the key in Climatools → Instellingen → API → API Sleutel genereren. The API is available on Plus and Enterprise plans. Each call uses one of your monthly API credits. Your key is used only to call the API on your behalf and to derive a private account id; it is never shown to anyone.
Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Climatools API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
Turn on the Climatools connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
climatools_list_companies | read | List companies List business customers (companies) in Climatools, with their addresses and tags. Filter by name or client number. Climatools API: GET /api/companies. |
climatools_get_company | read | Get a company Get one company by id. Climatools API: GET /api/companies/{id}. |
climatools_list_relations | read | List relations List private contacts (relations) in Climatools, with addresses and tags. Filter by first name, last name, email or client number. Climatools API: GET /api/relations. |
climatools_get_relation | read | Get a relation Get one relation (private contact) by id. Climatools API: GET /api/relations/{id}. |
climatools_list_installations | read | List installations List cooling, gas and other installations in Climatools, with brand, model and refrigerant circuits. Climatools API: GET /api/installations. |
climatools_list_refrigerants | read | List refrigerants List the refrigerants Climatools knows (for installation records). Climatools API: GET /api/refrigerants. |
climatools_create_company | write | Create a company Create a company (business customer) in Climatools. Name and address are required. Creates a new record each call; check with climatools_list_companies first to avoid duplicates. Climatools API: POST /api/companies. |
climatools_create_relation | write | Create a relation Create a private contact (relation) in Climatools. Last name and address are required. Creates a new record each call; check with climatools_list_relations first to avoid duplicates. Climatools API: POST /api/relations. |
climatools_usage_status | Usage status (free-tier meter) Report the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter. | |
climatools_request_feature | Request a missing feature Tell usefulapi that the user needs something the Climatools tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter. | |
climatools_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on Climatools (the free tier caps monthly usage). Plans: "monthly" — $9/month; "yearly" — $90/year (2 months free). Cancel any time: Pro then runs to the end of the paid period, so it also suits a one-time job. *A fair use limit applies. For heavy use (near Pro's limit): "plus" or "plus_yearly" — Pro+, $39/month or $390/year, unlimited tool calls (fair use limit: 100,000 a month); an existing Pro subscription changes to Pro+ in place (needs confirm: true; the price difference for the rest of the period is charged at once). Otherwise returns a short link to open in your browser (it opens Stripe Checkout); after payment the account upgrades automatically. Does not count against the meter. | |
climatools_cancel_subscription | Cancel the Pro subscription Cancel the caller's Climatools Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run climatools_upgrade later to undo the cancel before the period ends. Does not count against the meter. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper user | $9/mo · $90/yr | Unlimited* |
*Pro fair use limit: 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this Climatools server only. Subscribe with climatools_upgrade (it returns a Stripe Checkout link). Cancel any time with climatools_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running climatools_upgrade before then undoes the cancel. Or write to [email protected].

No. usefulapi is an independent service. It is not affiliated with or endorsed by Climatools. The server calls the Climatools API with your own Climatools access, so it sees only the data that your account can see.
Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.
The login page asks for your Climatools API key. See Before you connect for where to find it.
No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Climatools API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Climatools API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Climatools.
Yes, if you approve it. 2 of the 8 Climatools tools can create or change data. The other 6 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls (fair use limit: 10,000 tool calls a month), for this Climatools server only. Cancel any time: Pro then runs to the end of the paid period. Run climatools_usage_status to see how many calls you used.
Ask the AI to run climatools_upgrade: it returns a Stripe Checkout link. To cancel, run climatools_cancel_subscription. Pro continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with climatools_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.
This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
