Connect Meta Muse

Meta Muse connects to the Pallyy MCP server through a custom connector that Muse builds itself when you ask, authenticated with a Pallyy API key. Once built, Muse can list what's scheduled, create and edit posts for every connected network, import media from a URL, and manage calendar notes, from the Muse app or from WhatsApp. The server is included on every Pallyy plan.

What you need

• A Pallyy account on any plan, Free included.
• Muse, Meta's personal AI agent, which is rolling out in the US on iOS, Android, muse.ai, and WhatsApp.
• A Pallyy API key with the permissions Muse should have.

How to connect Muse

Muse has no settings form for MCP servers: custom connectors are created from a chat.

1. In Pallyy, open Settings > API keys and create a key named Muse. Grant Edit posts, add Upload media if it should import files, and leave Publish posts off to keep it drafting.
2. In Muse, ask it to create a custom connector for Pallyy and give it the server URL, for example:

Create a custom connector for Pallyy's MCP server at
https://app.pallyy.com/mcp. It uses a bearer token in the
Authorization header.

3. Muse builds the connector and asks for the credential. Paste the API key into its secure prompt; the key isn't shown in the chat.
4. Ask what's going out this week to check the connection. Muse keeps the connector for next time.

Pallyy isn't in the curated list under Muse's Settings > Connectors, and Meta doesn't review custom connectors.

Why Muse uses an API key

Muse builds its own client for the server, and Pallyy's authorization server only accepts OAuth redirects to claude.ai, chatgpt.com, cursor.com, or a local address. A bearer token, your API key, gives the connector the same access, bounded by the key's permissions and social set restriction.

Frequently asked questions

What is Meta Muse?

Muse is Meta's personal AI agent, announced in September 2026. It runs each person's agent in its own secure environment, works across iOS, Android, muse.ai, and WhatsApp, and connects to other services through connectors, including custom ones it builds on request.

Which permissions should the Muse key have?

Edit posts so it can draft, Upload media if it should import from links, and Publish posts off unless you want it scheduling unsupervised. Restrict the key to one social set for client accounts.

Can Muse attach a photo from my phone to a post?

No. The connector imports media from a public URL, so a photo has to be hosted somewhere first, or already in the Pallyy media library.

How do I disconnect Muse?

Delete the key under Settings > API keys in Pallyy. The connector stops working immediately, and a new key brings it back.
