How do I connect Claude or Claude Desktop to the Faaaster MCP server?

In Claude, Faaaster is added as a custom connector, tied to your Claude account: once added, it's available on claude.ai, in Claude Desktop and in Cowork. You authorize it with your Faaaster account, with no API key.

Server address: https://mcp.faaaster.io/mcp

To limit the agent to a single site, use This site's address instead, copied from the site's AI / MCP tab. Required roles, approvals and the agent's WordPress identity: How do I manage my Faaaster sites from my own AI agent?

Custom connectors are available on Claude's Free, Pro, Max, Ultra, Team and Enterprise plans; the Free plan allows only one.

Claude's interface changes in November 2026: the Customize entry becomes Plugins, in the sidebar, the chat menu and the settings. If you still see Customize, open Customize › Connectors wherever this guide says Plugins.

With an individual account

Open Plugins, from the sidebar or Claude's settings.
Add a custom connector: Add custom connector.
Name the connector Faaaster and enter https://mcp.faaaster.io/mcp as the address.
Finish according to the window shown:
- on a single screen, with Advanced settings: leave the OAuth client ID and secret empty, then click Add;
- in two steps: click Continue, keep the authentication settings Claude detected — never No sign-in —, then click Add.
If Claude hasn't already asked you to sign in, click Connect next to Faaaster, then sign in with your Faaaster account.

With a Team or Enterprise account

An owner of the Claude organization adds the connector first:

Open Organization settings › Connectors; since the redesign, the Connectors page sits in the Plugins group.
Click Add, then Custom; if Claude asks for the connector type, choose Web.
Name the connector Faaaster and enter https://mcp.faaaster.io/mcp — each member will only see the sites their own Faaaster account gives them access to.
Finish as in step 4 of the individual setup.

On Team, only Owners and Primary Owners can add a connector; on Enterprise, so can roles that include Manage access to Libraries.

Each member then opens Plugins, finds Faaaster (labeled Custom), clicks Connect and signs in with their own Faaaster account.

Use it in a conversation

Click the + button at the lower left of the chat box, then Connectors, and turn Faaaster on for this conversation. To check, ask: "List my Faaaster sites."

Authenticate again or revoke access

Sign in again: in Plugins, open Faaaster, then click Connect.
Revoke: disconnect the connector from Plugins.
Remove: click Remove or the connector's three-dot menu. An owner does it for the organization in Organization settings › Connectors.

The same menu lets you edit the connector's name or address. Its authentication settings can't be changed: remove the connector, then add it again.
