For agents & automationMCP · Claude Code · n8n · REST API

Social media automation for your agents.

Give any AI agent or automation the power to run your social media. Posta lets agents create, schedule, and publish across LinkedIn, TikTok, Instagram, YouTube, Pinterest, Facebook, Bluesky, and Threads — 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.

Built for agents & automation

Posta is the agentic social media scheduler — API-first, so your agents run the whole loop (generate, schedule, publish, report back) programmatically. Looking for the full social media scheduler overview? Start there.

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 let the agent 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, assembled by Posta. See the n8n workflow →
Monitor & respond
Pull comments via the API and react to publish/fail events with outbound webhooks — build a closed-loop social agent.
Agency at scale
Drive dozens of connected accounts from one codebase or n8n flow — consistent scheduling, zero tab-switching.
Outbound webhooksGet notified when posts publish, fail, or change status
Token authenticationSecure API tokens with granular scoping
OpenAPI specAuto-generate clients in any language

Post from your terminal

The terminal is one of many agent surfaces. Posta's Claude Code skill turns your IDE into a social media command center — create, schedule, and publish without ever leaving your editor, or hand the same skill to an autonomous agent.

Why agents choose Posta

Other social tools were built for humans clicking buttons. Posta is API-first, agent-first, and built for the class of automation that ships hundreds of posts a week — auto-formatting, closed-loop webhooks, and one token for every network.

Autonomous pipelines
No human in the loop, no broken crops
Your agent never has to reframe media. Posta detects faces in photos and videos and keeps them in frame when converting to portrait, landscape, or square — automatically, on every upload. No hand-off, no manual review step.
Smart crop example
One API, every network
One call, nine networks, every format
One POST /v1/posts, one MCP tool call, or one n8n node — Posta generates the variants for TikTok, Instagram, YouTube Shorts and more. Your pipeline never exports eight versions by hand.

Built for high-volume pipelines
Compression keeps quality where it matters and saves bytes where it doesn't — so automated, high-volume posting uploads fast and stays reliable. When a post goes live, an HMAC-signed webhook fires back to your agent so the next step knows it can run.

How agents use Posta

Posta is API-first and agent-first. Wire it into whatever your stack already speaks — MCP, Claude Code, n8n, or plain HTTP — and let the agent run the loop.

Step 1
Connect once
Generate a Posta API token, then pick a surface. One token, every network, every surface.
$ npx posta-mcp install
MCP serverClaude Code skilln8n nodeREST API
Step 2
Instruct in natural language or code
Your agent calls Posta as a tool. A Claude tool call via MCP, the Claude Code skill in plain English, an n8n node, or a typed POST — same Posta on the other side.
"Schedule a launch announcement to LinkedIn
and Bluesky for tomorrow at 9am."

Step 3
Posta executes and reports back
Posta auto-formats the media per platform, schedules or publishes, and fires HMAC-signed webhooks back to your agent when the post goes live. Closed-loop, hands-off.

Questions

Who is Posta for?
Developers, AI agents, automation engineers, and the creators they support — anyone who treats social posting as a pipeline rather than a manual task. Plug Posta into an MCP server, an n8n workflow, a Claude Code skill, or the REST API and let the agent do the rest.
What is the Posta MCP server?
Posta ships an MCP (Model Context Protocol) server so any MCP-capable client — Claude Desktop, Claude Code, Cursor, or your own agent — can create, schedule, and publish social media posts as tool calls. One install (npx posta-mcp), one token, every supported network.
Does Posta work with n8n?
Yes. The n8n-nodes-posta community node turns every Posta endpoint into a typed n8n node. We publish ready-to-fork workflows for blog-to-social, YouTube-to-social, product-launch campaigns, and LinkedIn carousel generation.
Can I post from Claude Code or the terminal?
Yes. The Posta Claude Code skill lets you create, schedule, and publish posts straight from your terminal or IDE using natural language. No dashboard required, no context-switch from your editor.
Does Posta publish directly to social networks?
Yes. Posta publishes directly to LinkedIn, TikTok, Instagram, YouTube, Pinterest, Facebook, Bluesky, and Threads via each platform's official API, and fires HMAC-signed webhooks back to your agent when posts go live — so closed-loop pipelines know exactly when they can act on a result.
How is this different from Buffer, Hootsuite, or Later?
Those tools are dashboards designed for humans clicking buttons. Posta is API-first and agent-first: full public REST API on every paid tier, HMAC-signed outbound webhooks, an MCP server, a Claude Code skill, and an n8n community node — none of which the dashboard-led incumbents ship. See the side-by-side comparison.
Can I influence the roadmap?
Yes. Early users help shape integrations, workflow and pricing. Tell us how you work and what your current agent stack looks like when you request access.
