Is this an official Postiz MCP server?

No. It is Memtro's MCP server with Memtro's Postiz connector behind it: the connector reads Postiz through its API with the credentials you connect on Dashboard → Connections, and Postiz publishes nothing here. The same endpoint carries every other system you connect and Memtro's memory tools.

Nothing on top of Memtro. One price per organisation by its number of users, from $50 a month for up to 10 users after a 7-day free trial, with every connector, the MCP server, jobs and memory included. You bring your own model keys.

Can it change anything in Postiz?

Only when you ask, and only what it has been granted: create a draft, schedule a post, or publish one now to the channels you name; move a post between draft and scheduled; change a not-yet-published post's platform settings; delete a post (with the rest of its group); upload an image or video to the media library from a URL. Every other tool reads, searches or lists. An administrator grants each acting tool by name per team, and a personal connection acts only after its owner allows it.

Any MCP client that speaks Streamable HTTP: Claude Code, Cursor, Claude Desktop, OpenCode, Codex, Zed, Windsurf, Cline and the Anthropic and OpenAI SDKs. There is no local process to run; the server is remote and authenticated with your key.

Postiz MCP server

Postiz in any MCP client, through Memtro: Postiz does not publish this server. Memtro's Postiz connector reads Postiz through its API with the credentials you connect, and one endpoint hands those tools, every other system you connect and Memtro's memory tools to Claude Code, Cursor, Claude Desktop or anything else that speaks Streamable HTTP, as you.

What the model can do

Postiz social media scheduling: connected channels (X, LinkedIn, Instagram, YouTube, TikTok and more), customers, posts in a date window with state, channel, content and published link, channel and post analytics, the media library and the next free slot; when you ask, can create a draft, schedule a post or publish one now, move a post between draft and scheduled, change its platform settings, delete it, and upload media from a URL.

Acts, when you ask

These change something in Postiz. The model is told to use them only when you ask for exactly that, and each one is granted by name: per team on a shared connection, by the owner on a personal one.

postiz_create_postCreates a post in Postiz for the channels you name.
postiz_set_post_statusMoves a post between draft and scheduled.
postiz_update_post_settingsChanges platform settings on a scheduled or draft post (a YouTube title, who can reply on X, a subreddit…); only the keys given change…
postiz_delete_postDeletes a post from Postiz together with every post in its group (the same post created for other channels at once).
postiz_upload_mediaCopies an image or video from a public URL into the Postiz media library, so a post can use it; nothing is published.

Connect it

First connect Postiz on Dashboard → Connections, then add Memtro to your client once. The Postiz tools appear alongside the tools of everything else you have connected; nothing is configured per connector.

Claude Code

The Memtro plugin registers the server and a skill for when to use it; the tools are then available in every session.

claude plugin marketplace add memtro-org/claude-memtro
claude plugin install memtro@memtro --config api_key=sk-memtro-...

Cursor

Add the server to .cursor/mcp.json in the project, or to the global file under ~/.cursor/.

{
  "mcpServers": {
    "memtro": {
      "url": "https://platform.memtro.com/api/mcp",
      "headers": {
        "Authorization": "Bearer sk-memtro-..."
      }
    }
  }
}

Claude Desktop

Create a personal API key on Dashboard → Profile → API keys. In Claude Desktop add an MCP server of type HTTP with URL https://platform.memtro.com/api/mcp and the header Authorization: Bearer sk-memtro-…

OpenCode

A remote server in opencode.json.

{
  "mcp": {
    "memtro": {
      "type": "remote",
      "url": "https://platform.memtro.com/api/mcp",
      "headers": {
        "Authorization": "Bearer sk-memtro-..."
      }
    }
  }
}

Pi

One command: pi mcp add memtro --url https://platform.memtro.com/api/mcp --bearer-token-env-var MEMTRO_API_KEY. Tools arrive as mcp__memtro__*. The pi-memtro extension registers it for you, alongside Memtro as the model.

Any other client

Add an MCP server of type HTTP (Streamable HTTP, stateless) at https://platform.memtro.com/api/mcp with the header Authorization: Bearer sk-memtro-.... Codex, Zed, Windsurf, Cline and the SDKs all take a remote server this way.

Who may use it

The key identifies the person, and the server offers that person the tools they may use everywhere else in Memtro. A shared Postiz connection is used by the teams an administrator granted it to, tool by tool, on the Permissions page; a personal connection is used by its owner alone, and its tools that act stay off until the owner allows them. See Teams and permissions and Connectors.
