Posta is 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 — wire any trigger to Posta in a few clicks.

Can I post to social media 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 slash-commands. 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.

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.

Replace Zapier social media steps with n8n + Posta

Zapier is the default for "RSS → social media" automations: easy to set up, runs in the cloud, native triggers for everything. But for serious social-posting pipelines — more than a few hundred runs a month, branching by platform, version control on the flows — the economics flip. Most teams move to n8n + Posta within their first year. This is why, and how.

Where Zapier gets expensive

Zapier prices per task, not per Zap (figures below as of mid-2026; check current pricing as plans shift). A "fan a blog post out to 8 networks" automation that posts to LinkedIn, TikTok, Instagram, YouTube, Pinterest, Facebook, Bluesky, and Threads is eight tasks per run in Zapier accounting. If your blog publishes 30 posts a month and you back-fill across a small library, you can burn through a paid plan's monthly task budget in a single weekend.

On n8n + Posta, the same flow is one n8n run (regardless of how many platforms) and a single Posta call that fans out internally. Pricing on both sides is flat-tier, not per-task.

Where Zapier gets brittle

Branching. Multi-platform branching with platform-specific captions ("draft a 280-char Bluesky post AND a 3000-char LinkedIn post from the same source") gets you into Paths and chained Zaps — fragile and expensive.
Loops over RSS items. Zapier's loop semantics are awkward; multi-item RSS triggers often spawn one task per item per platform.
No native version control. Zap definitions live in Zapier's UI. n8n stores workflows as JSON you can commit to git.
Limited webhook signing on outbound. Zapier's outbound webhooks don't HMAC-sign — so closed-loop pipelines need extra trust scaffolding.

The migration path

For most teams, the migration is straightforward: lift the existing Zap into n8n's visual editor, swap the per-platform "Post to LinkedIn / TikTok / Instagram / …" steps for a single Posta node. n8n's self-hosted edition runs free; n8n Cloud is typically meaningfully cheaper than Zapier's equivalent task-budget tier (check both vendors' current pricing for your volume).

A concrete example: RSS → multi-platform schedule

The Zap-shape:

RSS by Zapier            (trigger)
  ↓
ChatGPT                  (caption per platform — multiple Filters / Paths)
  ↓
Post to LinkedIn         (task 1)
Post to Instagram        (task 2)
Post to Bluesky          (task 3)
Post to Threads          (task 4)
... etc.                 (one task per network)

Per run: 1 trigger + N caption steps + N publish tasks = O(N) tasks.

The n8n + Posta shape:

RSS Trigger              (n8n)
  ↓
OpenAI / Claude          (one or N per-platform captions)
  ↓
Posta: Create Post       (one node — fan-out happens inside Posta)
       socialAccountIds: [42, 99, 17, 12]
       caption: ...
       (or per-platform configs via platformConfigurations)

Per run: 1 trigger + 1 n8n LLM step + 1 Posta call = O(1) n8n executions.

Same outcome, one n8n execution instead of N tasks. The Posta call itself fans out to every connected account in one API request — see the Posta n8n node reference for the typed parameter shape.

When to stay on Zapier

Be honest about the trade-off. Zapier still wins when:

Volume is genuinely low — only a few hundred tasks a month and you don't want to think about hosting.
You need integrations Posta and n8n don't cover — Zapier's catalog is the largest in the category (several thousand apps); n8n's is materially smaller; Posta covers eight social networks specifically.
You don't want to manage infrastructure — n8n Cloud is hosted, but self-hosting saves money only if you already have a dev team comfortable with a small VPS.

When to migrate

Most teams hit the migration tipping point when one of these is true:

Monthly Zapier bill running into the tens or hundreds of dollars and growing — flat-tier n8n + Posta will be cheaper.
You're writing Filters / Paths and chaining Zaps to get platform-specific behavior — visual branching in n8n is materially better.
You want to version-control your automations.
You need HMAC-signed outbound webhooks to close the loop with an agent.

Where to start

Fork one of our ready-made n8n templates (the blog-to-social one mirrors the most common Zap shape). Swap in your accounts, run it once, watch the per-run cost compared to your current Zap. 14-day free Posta trial covers everything except your n8n hosting.
