n8n

Direct REST access to an n8n instance — no MCP required. Covers Public API v1: workflow CRUD + activation, execution inspection/retry/stop, credentials, tags, variables, users, projects.

Usage

• Use for: Listing/filtering workflows, reading execution history, batch activate/deactivate, reading execution I/O programmatically.
• Skip for: Authoring new workflows from scratch (UI is better), interactive debugging, one-off manual test runs.
• Triggering a workflow is a webhook call, not /api/v1 — see Gotchas.

Credentials check

[ -n "$N8N_API_KEY" ] && [ -n "$N8N_BASE_URL" ] && echo "N8N: PRESENT" || echo "N8N: MISSING"

Never echo either variable directly.

If MISSING, respond to the user with EXACTLY this message (do NOT paraphrase, do NOT suggest manual JSON edits):
