Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 21

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

app

get_app

Fetch a single app's details (region, stack, status, URLs, flags). Scalingo API: GET /v1/apps/{app}. Returns { app }.

get_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.

get_app_stats

Real-time per-container resource stats (CPU / memory / swap usage) for an app. Scalingo API: GET /v1/apps/{app}/stats. Returns { stats: [...] }.

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 } }.

variables

list_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 }] }.

set_variables

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 }.

account

get_account

Fetch the authenticated user's account (id, email, username, fullname, company). Scalingo API: GET /v1/users/self. Returns { user }.

addon

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: [...] }] }.

addons

list_addons

List the addons (databases, services) provisioned on an app. Scalingo API: GET /v1/apps/{app}/addons. Returns { addons: [...] }.

apps

list_apps

List all Scalingo apps you can access in the current region. Scalingo API: GET /v1/apps. Returns { apps: [...] }.

collaborators

list_collaborators

List an app's collaborators (users invited to the app) and their status. Scalingo API: GET /v1/apps/{app}/collaborators. Returns { collaborators: [...] }.

containers

list_containers

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 }] }.

deployment

get_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 }.

deployments

list_deployments

List an app's deployments (most recent first), paginated. Scalingo API: GET /v1/apps/{app}/deployments. Returns { deployments: [...], meta: { pagination } }.

domains

list_domains

List an app's custom domains and their TLS/canonical status. Scalingo API: GET /v1/apps/{app}/domains. Returns { domains: [...] }.

operation

get_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.

regions

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: [...] }.

restart

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

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.

scalingo

scalingo_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}.

trigger

trigger_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 — questions

Answers built from our own checks of this server.

What can Scalingo do?

It exposes 21 tools, read directly from the server on our last check. Among them: get_account, get_app, get_app_logs, get_app_stats, get_deployment, get_operation and 15 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Scalingo mostly used for?

Its tools cluster around app and variables. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Scalingo working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 168 ms. The bar chart above shows every period we have measured.

How do I connect Scalingo?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Scalingo need an API key?

No. Scalingo completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 21 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Scalingo?

It answers our handshake in 168 ms on average, which is faster than 73% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Scalingo open source?

Yes — it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
