Give Antigravity Full Access to n8n. £19.95
ag8n is a privacy-first MCP server and skill pack that connects Google Antigravity directly to your n8n instance. The agent searches nodes, builds workflows, validates configs, deploys templates, and manages versions — without you touching the canvas.
Mode 1: Knowledge Base
No API Key- Search 1,084 nodes — 537 core + 547 community. Filter by category.
- Get exact input schemas — every property, every operation. The agent knows what a Slack node actually needs.
- Validate before you deploy — check any node config or entire workflow against n8n's actual requirements.
- Search 2,700+ templates — by task, by node type, by keyword. Pull complete workflow JSON.
- Browse full documentation — query docs for any MCP tool directly from the agent.
Mode 2: Workflow Management
API Key Required- Create workflows — build and push directly to your instance.
- Update workflows — full replacement or surgical diffs and patches.
- Deploy templates — pick a template, deploy it, auto-fix common errors on landing.
- Execute and test — trigger workflows, view execution history, confirm they run.
- Version control — rollback, prune, list versions. Undo what breaks.
- Autofix — the agent identifies and repairs common workflow errors automatically.
Cloud or self-hosted n8n. Works with both.
Why ag8n Exists
Point Antigravity at n8n without context and this is what happens: node configurations that look right but miss required fields. Expressions that break because n8n syntax is not standard JavaScript. Display Options ignored.
The MCP server gives the agent structured access to every node schema. The skill pack teaches it actual design patterns.
The result: workflows that are validated before they are deployed.
7 Skills. Loaded On Demand. No Context Bloat.
Expression Mastery
n8n expression syntax, data flow between nodes, debugging
Workflow Architect
Proven design patterns — webhooks, APIs, schedules, branches
Node Expert
Configuration protocols, Display Options, credential handling
Validation Debugger
Validate → fix loop. Catches errors before production.
API Operations
n8n API interaction, execution control, workflow management
Code Runner
JavaScript & Python execution inside n8n's runtime
Template Strategist
Search → deploy → modify from the template library
The MCP server gives the agent access to n8n. The skills tell it what to do when it gets there.
