PostWire MCP server

postwire-mcp

Your agent writes the post, picks the right shape for each network, and publishes it.

An MCP server for PostWire. Give Claude, Cursor, or any agent one idea and it publishes a native post to TikTok, Instagram, YouTube, X, LinkedIn, Reddit, Bluesky, Mastodon, Telegram and Discord — not the same text pasted ten times.

you:    "post the demo video — we shipped scheduling today"
agent:  → YouTube  title + description + tags, 16:9
        → TikTok   hook in the first line, 4 tags
        → LinkedIn no link in the body, link in the first comment
        → X        under 280, link in a reply
        published. 4/4.

Quick start

1. Get a free API key at postwire.io/dashboard.html and connect an account. One OAuth click — PostWire already holds the platform approvals, so there is no app review to wait for.
2. Add it to your MCP client:

{
  "mcpServers": {
    "postwire": {
      "command": "npx",
      "args": ["-y", "postwire-mcp"],
      "env": { "POSTWIRE_API_KEY": "pw_live_your_key" }
    }
  }
}

Client-specific setup: Claude Desktop · Claude Code · Cursor · VS Code · Windsurf

No key yet? list_platforms still answers, so you can see what is supported before signing up.

Tools

Failures are refused up front rather than half-published: a video network with no video, text over a platform's limit, or an account that was never connected all come back as a clear error before anything goes out. A four-network post never leaves you with two live and two silently missing.

Platforms

One OAuth click — TikTok · Instagram · YouTube · X · LinkedIn · Reddit · Facebook Token or webhook — Bluesky · Mastodon · Telegram · Discord

Pricing

Per brand, never per network. Connect a business once and every one of its accounts is included.

Ten client businesses on five networks each is $29 here. Buffer bills per channel; Ayrshare's comparable tier is $299.

REST too

Everything the MCP server does is a plain HTTP call, if you would rather not run an MCP client:

curl -X POST https://postwire.io/api/post \
  -H "Authorization: Bearer $POSTWIRE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"platforms":["x","bluesky"],"text":"shipped."}'
