What gets set up
Muse runs in Meta's cloud, so nothing is installed on your computer. The prompt asks Muse to create a custom connector: a connection, kept with your Muse account, that points at your account.
- Muse registers itself with your account and sends you a sign-in link. When you approve it, a key is created for Muse (or you choose one you already have), and Muse keeps the sign-in in its own secure credential store.
- There is no skill file to install. Each time Muse uses the connection, the connection itself gives Muse the rules for working with your account: create drafts by default, and check with you before anything is queued, scheduled or published.
Because the connection lives with your Muse account rather than on one computer, you set it up once.
Before you start
- Muse, signed in.
- Access to your account's API Console: open the account menu at the top right and choose API Console.
- You do not need to create an API key first. When you approve the connection in your browser, a key is created for Muse and connected for you.
- Do not paste an API key into a Muse conversation. Nothing in the setup asks you for one.
Set up the connection (once)
- In the API Console, open Connect your tools and choose Meta Muse.
- Under Add a connection, choose Copy setup block for Muse. There is one prompt for every computer.
- Open Muse, start a new conversation, paste the prompt and send it.
- Muse creates the connector and sends you a sign-in link. Open it.
- In the browser, sign in to your account if asked, review the request, leave Create a new API key for this application selected (or open Use an existing key instead to reuse a key you already have), and choose Approve.
- Return to Muse. It confirms the connection and lists the social profiles it can reach.
You should see the profiles your connected key can access. If nothing is listed, open API Console, then API keys, and check that the key has access to at least one workspace.
Muse may mention that Meta does not review custom connectors. That notice applies to every connector added this way. The connection reaches your account only through the sign-in you approved, and you can end it from the API Console at any time.
Ask in your own words instead
If you prefer not to paste the prompt:
- On the setup page, open Other Connection Methods and copy the MCP server address shown there.
- In Muse, ask it to create a custom connector with that address.
- Approve the sign-in link Muse sends you, as in step 5 above.
Without the prompt, Muse does not get your ground rules up front, so tell it yourself: create drafts by default, never publish unless asked, confirm the profiles, date, time and time zone first, and never repeat a credential back.
Using the tools
Ask for what you want in plain language: draft three posts for next week, schedule this post to Instagram and LinkedIn on Tuesday at 10am, show me last month's published messages, set up a giveaway. Muse creates drafts by default and checks with you before anything is queued, scheduled or published.
Two things to know:
- The prompt asks Muse to save the connector, so later conversations can use it without setting it up again. If a conversation does not seem to have it, ask Muse to use your social media connector.
- Posts Muse creates appear in your account like any other post, so you can review or edit them there before they go out.
Fix a problem
Muse asks you for an API key or a token.
- Never paste one. This connection signs in through your browser. Tell Muse the connector uses a browser sign-in, or start a new conversation and paste the setup prompt again.
The sign-in link does not open, or says the request has expired.
- Ask Muse for a new sign-in link and approve it straight away.
Muse says it cannot reach the server, or the connector fails to connect.
- Check that Muse used exactly the MCP server address shown on the setup page. Copy it from the page rather than retyping it.
- Your account may have been unreachable for a moment, usually during an update. Wait a minute and ask Muse to try again.
Nothing is listed when you ask for your profiles.
- The connected key has no workspace access. Open API Console, then API keys, and give the key access to at least one workspace.
Muse stopped working with your account, or says the connector is signed out.
- The sign-in was ended, for example with Sign out apps in the API Console. Ask Muse to reconnect the connector and approve the new sign-in link.
Muse answers from the web or invents settings.
- The connector is not active in that conversation. Ask Muse to use your social media connector, or start a new conversation. Never paste a key.
The connection is listed under Custom API in the API Console instead of Meta Muse.
- Muse registered itself under a different name. The connection works exactly the same way; only the label differs.
For more help, open Fix a problem in the API Console.
Disconnecting
To sign Muse out of your account, open API Console, then Connect your tools, then Meta Muse. On the connection, open Setup and troubleshooting and choose Sign out apps. This does not revoke your API key, and every other tool that uses that key keeps working. To remove access entirely, revoke the key under API keys.
Muse keeps the connector in its own list until you remove it there. Removing it in Muse does not change your API key.
