README

n8n-guard

An MCP server for the operational layer underneath the n8n Public API.

Most n8n MCP servers on the registry wrap the same public endpoints: list workflows, list executions, create, activate, delete. That is useful for building workflows. It is close to useless for keeping a self-hosted instance alive, because the things that actually take an instance down are not in that API at all.

n8n-guard answers the four questions the API cannot:

How big is the datastore, and when does it become a problem? The Public API has no endpoint for database size. n8n-guard reads the SQLite file or queries Postgres directly, breaks the size down per table, derives the growth rate, and tells you how many days of headroom are left.
Which executions are stuck? Listing executions by status is not detection. A run sitting in running looks identical to a healthy long job until you compare it against what that workflow normally takes. n8n-guard builds a per-workflow median from finished runs and flags the outliers.
What is retention costing? How many execution records are stored, how far back they reach, and what a given retention window would free.
Has the instance drifted from git? Existing servers diff one API object against another. n8n-guard diffs the running instance against the JSON exports in a repository: live but never exported, exported but deleted, and content that quietly diverged.

It is strictly read-only. n8n-guard never writes to your instance, never deletes executions, and never activates or edits a workflow. It reports; you decide.

Install

npx -y n8n-guard

Requires Node.js 22 or newer (it uses the built-in node:sqlite). For a permanent install use npm install -g n8n-guard.

  "mcpServers": {
    "n8n-guard": {
      "command": "n8n-guard",
      "env": {
        "N8N_URL": "https://n8n.example.com",
        "N8N_API_KEY": "n8n_api_...",
        "N8N_SQLITE_PATH": "/var/lib/n8n/.n8n/database.sqlite",
        "N8N_GIT_REPO_PATH": "/srv/workflow-exports"
      }
    }
  }
}

Configuration

Everything is an environment variable. There are no hardcoded hosts, paths, container names or accounts, so the server runs against any self-hosted instance.

Variable	Required	Default	Purpose
`N8N_URL`	no	`http://localhost:5678`	Base URL of the instance
`N8N_API_KEY`	for execution and workflow checks	none	Public API key (Settings, n8n API)
`N8N_SQLITE_PATH`	for datastore checks on SQLite	none	Path to `database.sqlite`
`N8N_POSTGRES_URL`	for datastore checks on Postgres	none	Connection string, takes precedence over SQLite
`N8N_GIT_REPO_PATH`	for the drift check	none	Checkout holding exported workflow JSON
`N8N_GUARD_STUCK_MINUTES`	no	`15`	Minutes in `running` before a run counts as stuck
`N8N_GUARD_DB_WARN_BYTES`	no	`1073741824` (1 GB)	Datastore warning threshold
`N8N_GUARD_DB_CRITICAL_BYTES`	no	`4294967296` (4 GB)	Datastore critical threshold
`N8N_GUARD_TIMEOUT_MS`	no	`15000`	Per-request API timeout

Partial configuration is a supported mode, not an error. With only N8N_URL and N8N_SQLITE_PATH you still get disk and retention answers; the API-backed checks report that they are unconfigured and the rest of the run continues.
