Inspect Exoscale: instances, volumes, SKS, DNS, IPs, quotas and usage; start, stop, reboot VMs. Hosted by usefulapi — connect from Claude, 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": {
"exoscale": {
"url": "https://exoscale.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"exoscale": {
"type": "http",
"url": "https://exoscale.usefulapi.io/mcp"
}
}
}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.
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.
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.
| Tool | Type | What it does |
|---|---|---|
exoscale_list_zones | read | List zones List the Exoscale zones (data centers) with their API and object-storage endpoints. Compute, storage and network resources live in one zone each. GET /zone. |

exoscale_get_dns_domain | read | Get DNS domain Details of one DNS domain. GET /dns-domain/{id}. |
exoscale_list_dns_records | read | List DNS records List the records of one DNS domain: name, type, content, TTL, priority. Use exoscale_list_dns_domains for the domain id. GET /dns-domain/{domain-id}/record. |
exoscale_usage_status | Usage status (free-tier meter) Report the caller's current free-tier usage this month: calls used, monthly limit, remaining, and whether the cap is reached. Read-only; does not count against the meter. | |
exoscale_request_feature | Request a missing 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. | |
exoscale_upgrade | Upgrade to Pro (unlimited) Subscribe to the Pro plan for UNLIMITED Exoscale tool calls (the free tier caps monthly usage).

Does not count against the meter. | |
exoscale_cancel_subscription | Cancel the Pro subscription Cancel the caller's Exoscale Pro subscription at the end of the paid period (no refund for the current period; unlimited calls continue 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. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 100 tool calls / month |
| Proper user | $9/mo · $90/yr | Unlimited |
Pro covers this Exoscale server only. Subscribe with exoscale_upgrade (it returns a Stripe Checkout link). Cancel any time with exoscale_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running exoscale_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 Exoscale. The server calls the Exoscale API with your own Exoscale access, so it sees only the data that your account can see.
The login page asks for your API key, API secret and Default zone. See Before you connect for where to find them.
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.
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.
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.
The Free plan gives 100 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls, for this Exoscale server only. Run exoscale_usage_status to see how many calls you used.
Ask the AI to run exoscale_upgrade: it returns a Stripe Checkout link. To cancel, run exoscale_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 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.
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, 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.
