restart_appMUTATES Scalingo infrastructure — restarts an app's containers.No findings
Why it is in this group
- The name "restart_app" says "restart": a word for a change.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
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.
Annotations the server declares
- title: Restart app
- destructiveHint: true
scale_appMUTATES Scalingo infrastructure — sets the container formation (number and/or size of each process type).No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
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.
Annotations the server declares
- title: Scale app
- destructiveHint: true
set_variablesMUTATES Scalingo infrastructure — creates or updates environment variables in bulk (each { name, value } is created if new or updated if it exists).No findings
Why it is in this group
- The name "set_variables" says "set": a word for a change.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
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 }.
Annotations the server declares
- title: Set environment variables (bulk)
- destructiveHint: true
trigger_deploymentMUTATES Scalingo infrastructure — triggers a new deployment from a source archive URL (a tar.gz reachable by Scalingo).No findings
Why it is in this group
- The name "trigger_deployment" says "trigger": a word for a change.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
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 }.
Annotations the server declares
- title: Trigger a deployment
- destructiveHint: true

5 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
