PostFiber for Muse Code

Made by Meta

Add the MCP server to Muse Code, the coding agent of Meta, with your API key.

Connect over MCP

MCP server address

https://www.postfiber.com/mcp

Create an API key in PostFiber under API keys. It is shown once, and it can be limited to one project, to read-only access or to the permissions you choose.

Create an API key in PostFiber under API keys.
Add the server to Muse Code with the settings below.
Ask Muse Code to list your PostFiber channels to check the connection.

Add this to ~/.config/muse/settings.json (the file must keep "schema_version": 1), with your key in the POSTFIBER_API_KEY environment variable:

{
  "schema_version": 1,
  "mcp_servers": {
    "postfiber": {
      "transport": "streamable_http",
      "url": "https://www.postfiber.com/mcp",
      "headers": {
        "Authorization": "Bearer ${POSTFIBER_API_KEY}"
      },
      "mode": "optional"
    }
  }
}

The server is marked optional because Muse Code treats a server as required by default and stops the whole run when it cannot start one. Run /mcp in an interactive session to see the connected servers and their tools.

Try it

List my connected channels.
Draft a post about our launch for tomorrow at 9:00 and save it as a draft.
Show me what is scheduled for this week.

Keep a person in the loop. An agent works with the permissions of the key, or of the person who connected it. Ask it to save drafts or schedule posts, look at the calendar before anything goes out, and give each key only the project and the permissions it needs. A key or a connected app you revoke stops working at once.
