Connect Build Agent to a supported MCP server

Connect a supported MCP server to Build Agent to access external tools and resources in the chat panel when building and editing apps.

Before you begin

Before you can enable an MCP server in Build Agent, an administrator must approve it as an AI asset in AI Control Tower. Each MCP server requires this approval, regardless of whether the server is enabled by default.

You must have Connect Hub installed.

The end-to-end flow for making an MCP server available is:

1. The administrator adds the MCP server as a Workflow Data Fabric (WDF) connection.

2. The administrator approves the server as an AI asset in AI Control Tower.

3. You authenticate the connection in Personal Integrations.

4. You enable the MCP server in Build Agent settings.

For details on enabling MCP connections, see Client registration using custom connector.

Note: An allowlist process is required to connect the Build Agent MCP client to the Figma MCP server. Contact Now Support to initiate the process.

Individual MCP servers are enabled by default, but the complete flow must be completed before any server is available for use.

For details on adding a new MCP connection in Workflow Data Fabric, see Model Context Protocol connectors.

See MCP connections and Build Agent for a list of supported MCP servers.

Note: MCP connections are available in both ServiceNow Studio and the ServiceNow IDE.
