Manage Scalingo PaaS apps, deployments, containers, logs and env vars from your AI assistant. 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": {
"scalingo": {
"url": "https://scalingo.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"scalingo": {
"type": "http",
"url": "https://scalingo.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 Scalingo API token.
Create one at dashboard.scalingo.com → your name → API tokens (it looks like tk-us-…). Your token 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 Scalingo API token. 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 Scalingo connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
list_apps | read | List apps List all Scalingo apps you can access in the current region. Scalingo API: GET /v1/apps. Returns { apps: [...] }. |
get_app | read | Get an app Fetch a single app's details (region, stack, status, URLs, flags). Scalingo API: GET /v1/apps/{app}. Returns { app }. |
list_containers | read | List containers (formation) List an app's container formation — the running process types with their amount and size (the current scaling). Scalingo API: GET /v1/apps/{app}/containers. Returns { containers: [{ name, amount, size }] }. |
get_app_stats | read | Get container stats Real-time per-container resource stats (CPU / memory / swap usage) for an app. Scalingo API: GET /v1/apps/{app}/stats. Returns { stats: [...] }. |
list_deployments | read | List deployments List an app's deployments (most recent first), paginated. Scalingo API: GET /v1/apps/{app}/deployments. Returns { deployments: [...], meta: { pagination } }. |
get_deployment | read | Get a deployment Fetch a single deployment's details (status, git_ref, pusher, image size, timestamps). Scalingo API: GET /v1/apps/{app}/deployments/{deployment_id}. Returns { deployment }. |
get_app_logs | read | Get recent app logs Fetch recent application log lines. Scalingo returns an authenticated logs_url (GET /v1/apps/{app}/logs → { logs_url }); this tool then downloads the last N lines from it (dump mode) and returns them as text. Returns { logs_url, lines }. If the follow-up download fails, only logs_url is returned so you can fetch it yourself. |
list_variables | read | List environment variables List an app's environment variables. WARNING: this exposes secret VALUES (API keys, database URLs, etc.). Scalingo API: GET /v1/apps/{app}/variables. Returns { variables: [{ id, name, value }] }. |
list_collaborators | read | List collaborators List an app's collaborators (users invited to the app) and their status. Scalingo API: GET /v1/apps/{app}/collaborators. Returns { collaborators: [...] }. |
list_domains | read | List domains List an app's custom domains and their TLS/canonical status. Scalingo API: GET /v1/apps/{app}/domains. Returns { domains: [...] }. |
list_addons | read | List addons List the addons (databases, services) provisioned on an app. Scalingo API: GET /v1/apps/{app}/addons. Returns { addons: [...] }. |
list_addon_providers | read | List addon providers List the addon providers available on Scalingo (databases, monitoring, etc.) with their plans embedded. Scalingo API: GET /v1/addon_providers. Returns { addon_providers: [{ ..., plans: [...] }] }. |
list_app_events | read | List app events List an app's activity events (deployments, scaling, restarts, collaborator changes, etc.), paginated. Scalingo API: GET /v1/apps/{app}/events. Returns { events: [...], meta: { pagination } }. |
get_operation | read | Get an operation Poll the status of an asynchronous operation (e.g. a scale or restart returns an operation to track). Scalingo API: GET /v1/apps/{app}/operations/{operation_id}. Returns { operation } with status pending|running|done|error. |
list_regions | read | List regions List the Scalingo regions available to your account, each with its API/dashboard/database hosts. Useful to discover the right SCALINGO_REGION. Scalingo API: GET (auth host) /v1/regions. Returns { regions: [...] }. |
get_account | read | Get current account Fetch the authenticated user's account (id, email, username, fullname, company). Scalingo API: GET /v1/users/self. Returns { user }. |
scalingo_request | read | Raw read request Power-user escape hatch: GET any Scalingo API path not wrapped by a dedicated tool. READ-ONLY — only GET is allowed. Path is taken after /v1 (e.g. "/apps/my-app/alerts"). By default hits the regional API; set on_auth_host:true for auth-host resources (regions, scm_integrations, tokens). Scalingo API: GET {path}. |
restart_app | write | Restart app MUTATES Scalingo infrastructure — restarts an app's containers. Optionally restart only specific process types via scope; omit scope to restart everything. Returns 202 Accepted (track via get_operation). Scalingo API: POST /v1/apps/{app}/restart. |
scale_app | write | Scale app MUTATES Scalingo infrastructure — sets the container formation (number and/or size of each process type). Only the container types you include are changed. Returns 202 Accepted (track via get_operation). Scalingo API: POST /v1/apps/{app}/scale. |
set_variables | write | Set environment variables (bulk) MUTATES Scalingo infrastructure — creates or updates environment variables in bulk (each { name, value } is created if new or updated if it exists). This usually triggers a restart to apply the new env. Names ≤64 chars, values ≤8192 chars. Scalingo API: PUT /v1/apps/{app}/variables. Returns { variables }. |
trigger_deployment | write | Trigger a deployment MUTATES Scalingo infrastructure — triggers a new deployment from a source archive URL (a tar.gz reachable by Scalingo). To roll back, re-deploy a previous git_ref/archive — there is no separate rollback endpoint. Scalingo API: POST /v1/apps/{app}/deployments. Returns { deployment }. |
scalingo_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. | |
scalingo_request_feature | Request a missing feature Tell usefulapi that the user needs something the Scalingo 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. | |
scalingo_upgrade | Upgrade to Pro (unlimited) Subscribe to the Pro plan for UNLIMITED Scalingo tool calls (the free tier caps monthly usage). Choose monthly ($9/month) or yearly ($90/year — 2 months free) billing. Returns a Stripe Checkout link to open in your browser; after payment your account upgrades automatically. Does not count against the meter. | |
scalingo_cancel_subscription | Cancel the Pro subscription Cancel the caller's Scalingo 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 scalingo_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 |
| Pro | $9/mo · $90/yr | Unlimited |
Pro covers this Scalingo server only. Subscribe with scalingo_upgrade (it returns a Stripe Checkout link). Cancel any time with scalingo_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running scalingo_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 Scalingo. The server calls the Scalingo API with your own Scalingo access, so it sees only the data that your account can see.
The login page asks for your Scalingo API token. 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 Scalingo API token. 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 Scalingo 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 Scalingo.
Yes, if you approve it. 4 of the 21 Scalingo tools can create or change data. The other 17 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 Scalingo server only. Run scalingo_usage_status to see how many calls you used.
Ask the AI to run scalingo_upgrade: it returns a Stripe Checkout link. To cancel, run scalingo_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 scalingo_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.
