What can I ask?

Turn on the Exoscale connector, then ask in plain words. The AI picks the tools.

What you can do with Exoscale in Claude and ChatGPT

For developers and sysadmins who run instances, Kubernetes and DNS on Exoscale.

List the instances in a zone and their state

The AI lists compute instances of a zone with state, type, IP addresses and security groups, and reads one in detail. You get an inventory per zone.

Check how close you are to your quotas

The AI reads the usage and the limit of each resource quota, such as instances, volumes and elastic IPs.

Break down last month's usage by product

The AI reads the usage report for one month with product, quantity and unit per line, and groups it for you.

Check the DNS records of a domain

The AI lists your DNS domains and the records of one domain: name, type, content, TTL and priority.

Start, stop or reboot an instance

The AI starts a stopped instance, stops or reboots a running one, and then checks the state of the operation until it ends.

Changes data

Review firewall rules, elastic IPs and volumes

The AI lists security groups, with their rules when the API includes them, elastic IPs, and block storage volumes with the instance each one is attached to.

How do I connect Exoscale?

Before you connect

The login page asks for your API key, API secret and Default zone.

In the Exoscale portal open IAM → API Keys and create a key. A role limited to read access (it must allow reading the organization) is enough for every tool except start, stop and reboot of instances. The secret is shown only once. Pick the zone where most of your resources live; every tool can still ask for another zone. Your key and secret are used only to sign requests to the Exoscale API on your behalf; the secret is never sent and never shown to anyone.

  4. In Plugins, install Exoscale, then choose it in a chat.

No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.

Claude Code

Run this command, then run /mcp in Claude Code to log in:

claude mcp add --transport http exoscale https://exoscale.usefulapi.io/mcp

Cursor

Add to Cursor or add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "exoscale": {
      "url": "https://exoscale.usefulapi.io/mcp"
    }
  }
}

VS Code

Add to VS Code or add this to .vscode/mcp.json:

{
  "servers": {
    "exoscale": {
      "type": "http",
      "url": "https://exoscale.usefulapi.io/mcp"
    }
  }
}

Codex

Run these commands. The second one opens the login page:

codex mcp add exoscale --url https://exoscale.usefulapi.io/mcp
codex mcp login exoscale

Other clients

Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.

https://exoscale.usefulapi.io/mcp

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 API key, API secret and Default zone. 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.

Each paid plan covers this Exoscale server only. Ask your AI to run exoscale_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with exoscale_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with exoscale_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Your usefulapi plan · 4

  • Usage status (free-tier meter)exoscale_usage_status
    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.
  • Request a missing featureexoscale_request_feature
    Tell usefulapi that the user needs something the Exoscale 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.
  • Upgrade to Pro or Pro+exoscale_upgrade
    Get a paid plan for Exoscale (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter.
  • Cancel the Pro subscriptionexoscale_cancel_subscription
    Cancel the caller's Exoscale 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 exoscale_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with Exoscale in Claude or ChatGPT?

List the instances in a zone and their state. Check how close you are to your quotas. Break down last month's usage by product. Check the DNS records of a domain. Start, stop or reboot an instance. Review firewall rules, elastic IPs and volumes. See what you can do for the details.

Is this an official Exoscale product?

No. usefulapi is an independent service. It is not affiliated with or endorsed by Exoscale. The server calls the Exoscale API with your own Exoscale access, so it sees only the data that your account can see.

Can I connect Exoscale to Claude or ChatGPT?

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.

What do I need to connect?

The login page asks for your API key, API secret and Default zone. See Before you connect for where to find them.

Do I put my Exoscale key or an Authorization header in the client config?

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 API key, API secret and Default zone. 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.

How do you keep my Exoscale credentials?

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Exoscale 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 Exoscale.

Can the AI change my Exoscale data?

Yes, if you approve it. 3 of the 26 Exoscale tools can create or change data. The other 23 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.

What does it cost?

The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Exoscale server only. Cancel any time: your paid plan then runs to the end of the paid period. Run exoscale_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run exoscale_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run exoscale_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a Exoscale tool that I need is missing?

Tell the AI what you wanted to do. It can send the request with exoscale_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.

Which AI clients can I use?

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.

Need a tool this server does not have, or a connection to another system? We build custom integrations and MCP servers.
