Some agents add MCP servers from a chat message instead of a settings page. Muse and Instinct work this way. For Grok Bot, install the fal plugin instead. See Grok Bot setup.

​
Setup

1

Ask the agent to add fal

Paste this message into a new chat:
If the agent asks for approval to add the server, approve it.
2

Sign in

Complete browser sign-in when the agent asks. Never paste an OAuth token or API key into the chat.
3

Check tools

Ask the agent to find a fal model without running it.

​
Agent notes

Muse adds an MCP server that is not in its list as a Custom Connector, which is the Muse name for it. Paste this message instead of the general one:
Muse adds the server, tests it, and saves it as a skill so that it stays available in later chats.If Muse asks for a key instead of browser sign-in, create a fal API key. Enter it as the header Authorization: Key <key_id>:<key_secret> when Muse asks for it in its secure credentials form. Do not paste the key into the chat. A key connection uses the account that owns the key.Meta does not review custom connectors. In Muse Settings, choose when Muse asks for your approval before it uses fal.

​
Next steps

After connecting, try your first generation. For account selection, tools, and troubleshooting, see the fal MCP overview.
