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
- 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.
- 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
| Tool | What it does |
|---|---|
generate_posts | Smart Distribute. One prompt → a draft written for each platform: character limits, hashtag conventions, YouTube SEO title+tags, hook-first captions for TikTok, link-in-comment for LinkedIn. Returns drafts for you to review. |
post_to_social | Publishes. Takes one text for all, or per_platform drafts from generate_posts. |
get_post_status | Publish state for platforms that report one back (TikTok and YouTube process asynchronously). |
list_platforms | Every supported network and the fields it needs. Works without a key. |
my_account | Plan, posts used this month, which accounts are connected. |
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.
| Brands | Posts/month | ||
|---|---|---|---|
| Free | 1 | 30 | no card |
| Starter | 3 | 300 | $9/mo |
| Pro | 10 | 2,000 | $29/mo |
| Agency | 50 | 15,000 | $99/mo |
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."}'
