How to Automate Social Media Posts with n8n and AIGE MCP

Automating social media with n8n and AIGE connects your marketing database to generative AI pipelines via the Model Context Protocol (MCP). Your n8n workflow triggers content briefs, calls AIGE tools like antix_generate_image or antix_generate_deck, and passes rendered assets to a scheduler for human review. This architecture replaces fragile scraping scripts with secure, production-grade API endpoints.

Agencies and growth engineers frequently build automation loops in n8n to generate content from RSS feeds, Notion tables, or Airtable bases. However, connecting standard image APIs usually produces generic, off-brand graphics with no character continuity. By connecting n8n directly to AIGE's registered MCP server, you can trigger complex creative workflows—including consistent actors, brand color kits, and multi-slide decks—from standard webhook nodes.

Step 1: Obtain your AIGE API key and configure MCP credentials

To communicate with AIGE from an external automation orchestrator, create an API key in your studio settings. This key authenticates your requests against the official MCP server (ws.aige/antix) and deducts standard credit rates from your plan balance without separate per-seat developer licensing.

In n8n, you can interface with AIGE through HTTP Request nodes calling the REST/JSON endpoints or via an MCP-compatible agent node. Provide your bearer token in the authorization header and set the target endpoint to https://aige.ws/mcp. Test the connection by calling tools/list to verify available capabilities.

Step 2: Triggering content briefs from your CMS or database

The first step in your n8n workflow is reading content triggers. Configure a schedule trigger or a webhook node listening to updates in Notion, Airtable, or a Google Sheet containing your editorial topics.

Your workflow extracts the post topic, primary hook, and target format. A formatting code node transforms this data into a structured brief payload, defining the required asset type: an image prompt, an Atelier carousel outline, or a 9:16 vertical video draft.

Step 3: Executing asset generation with AIGE tool calls

Pass your brief into the AIGE MCP tool node. For single-image assets, invoke antix_generate_image, specifying the model (Nano Banana 2 or Nano Banana Pro) and passing your saved character ID if you want to include your brand spokesperson.

For multi-slide carousels, call antix_generate_deck. The server compiles slide copy, pairs it with an Atelier layout template, and returns high-resolution slide URLs ready for preview.

Step 4: Storing assets and notifying your review team

Once AIGE returns the completed generation payload, your n8n workflow routes the media files to cloud storage or your review channel. Send a notification to your Slack or Discord marketing channel containing the draft image, slide previews, and generated caption options.

Include interactive review buttons in your message: "Approve for Scheduling" or "Request Revision." This human-in-the-loop checkpoint ensures that no automated asset publishes to your live feed without team sign-off.

Available MCP tools in the AIGE server catalog

The AIGE MCP server exposes specific tools designed for automated workflow integration:

Because generation costs correspond directly to standard studio rates, you can track credit expenditure programmatically using antix_get_balance before triggering large batch jobs.

Important automation rails and publishing policy

When engineering social automations, maintain compliance with platform policies and AIGE guidelines:

• No direct autonomous publishing: AIGE does not provide automated direct-to-Instagram posting. Route your approved assets to verified third-party schedulers (Buffer, Planable, Later) through their official Meta APIs.

• Rate limit moderation: Space batch triggers by several seconds in n8n to allow task queues to process and avoid concurrency spikes.

• Always retain human review: Verify brand voice, spelling, and factual accuracy before scheduling.
