What is the Postwire MCP server?

Let any AI agent post to TikTok, Instagram, X, YouTube, LinkedIn, Bluesky & more via MCP. The postwire mcp server wraps that behind the Model Context Protocol, so an assistant can use it rather than through you.

What it actually does

  1. Get a free API key at https://postwire.io/dashboard.html and connect your accounts. 2. Add to your MCP client (e.g. Claude Desktop / Cursor):

Configuration

You will need one environment variable: POSTWIRE_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Adding it to your client

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.

When to reach for it

Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. It is maintained by Perufitlife; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Caveats

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the postwire mcp server does with a few real requests.

Frequently asked questions

It connects Postwire to MCP-compatible AI assistants such as Claude and Cursor. Instead of copying data back and forth by hand, the assistant works with Postwire directly.
