To add MCP servers to a Databricks agent and grant permissions, you configure the required resources and access levels directly in databricks.yml. This exposes the back-end services to the Databricks runtime and prevents deployment errors.

Runtime permission errors occur when required access levels are missing from databricks.yml. You must explicitly grant permissions for new tools like Genie spaces or vector search before deployment to satisfy Databricks App template sequencing requirements.

Yes, you can configure Unity Catalog functions and vector search indexes as agent tools. Adding these resources to databricks.yml ensures they are enabled on demand and accessible by the Databricks runtime without encountering access errors.

The best way to enable Genie spaces in a Databricks App template is to add the resource to your agent's toolset and update databricks.yml. This ensures operational safety by granting necessary permissions before deployment.

You need to update databricks.yml when integrating new MCP servers, Genie spaces, vector search indexes, or Unity Catalog functions. Updating this file ensures the Databricks runtime grants required permissions and avoids deployment sequencing failures.
