Social media automation for your AI agents
Give any agent or automation the power to run your social media. Posta lets agents create, schedule, and publish across 8 networks — through an MCP server, a Claude Code skill, the n8n node, or a public REST API. Media auto-formats per platform and webhooks report back when posts go live.
How agents use Posta
1
Connect
Plug Posta into whatever your agent speaks — MCP, the Claude Code skill, the n8n node, or the REST API. One Posta token, every channel.
2
Instruct
Drive it with natural language or code: "draft and schedule this week's posts," or a single
POST /v1/posts call from your pipeline.3
Posta executes
Posta formats media per platform, schedules or publishes, and fires a webhook on every result — so the agent can close the loop.
What you can build
Autonomous content pipeline
Watch an RSS or blog feed, draft a post with an LLM, and schedule it — hands-off. See the n8n workflow →
Launch agent
One instruction turns a product into a multi-day, multi-platform campaign with per-network copy. See the n8n workflow →
Repurposing agent
Feed in one asset or a YouTube video and fan it out to Reels, Shorts, TikTok, and feeds. See the n8n workflow →
Carousel generator
Summarize an article into a polished LinkedIn carousel PDF — AI text over AI backgrounds. See the n8n workflow →
Monitor & respond
Pull comments via the API and react to publish/fail events with outbound webhooks — a closed-loop social agent.
Agency at scale
Drive dozens of connected accounts from one codebase or n8n flow — consistent scheduling, zero tab-switching.

Agents can post to every platform Posta supports — LinkedIn, TikTok, Instagram, YouTube, Pinterest, Facebook, Bluesky, and Threads. Each platform's requirements — aspect ratios, caption limits, privacy settings — are handled automatically.
Frequently asked questions
How can an AI agent post to social media?
Connect the agent to Posta through an MCP server, a Claude Code skill, the n8n node, or the REST API. The agent can then create, schedule, and publish to all 8 networks, with media auto-formatted per platform.
Which AI tools and agent frameworks are supported?
Any MCP client (Claude Desktop, Cursor, Windsurf, VS Code, Zed), Claude Code via the Posta skill, n8n via the community node, and any language or framework via the REST API and webhooks.
Can agents schedule posts and react to events?
Yes. Agents can schedule posts for any future time, and Posta emits outbound webhooks on publish, fail, or status change — so an agent can close the loop and respond automatically.
Is there a free way to try agent posting?
Yes — a 14-day free trial, no credit card required. The MCP server, Claude Code skill, and n8n node are all free and open source.
