Frequently Asked Questions

You connect Databricks Agent Bricks to the StackOne MCP gateway via a custom MCP server on Databricks Apps: open Compute → Apps → Create app → MCP Server template, name it starting with mcp-, point it at the gateway URL with OAuth, and create. See the setup docs. Requires Unity Catalog.
An MCP gateway (also called an MCP aggregator) is a single endpoint that connects an AI agent to multiple MCP servers via the Model Context Protocol. Some gateways route traffic to MCP servers customers operate themselves; others, like StackOne, provide the MCP servers as a managed service — pre-built for 470+ enterprise SaaS apps, including ones with no official MCP server today.
You can connect Agent Bricks to 470+ live MCP servers through StackOne, spanning CRM, HRIS, ATS, ticketing, and finance — Salesforce, Workday, Greenhouse, and more. Each is reachable through one gateway URL instead of wiring up servers app by app. Browse the full list in the directory on this page, or build your own.
Databricks Agent Bricks ships 6 first-party MCP partners — all data vendors (You.com, Glean, S&P Global, FactSet, D&B, Moody's). StackOne adds the other 470+ operational SaaS — every app reachable through one Custom MCP Server registration instead of N separate ones, auth managed once in the dashboard, and tool definitions loaded only when relevant to the prompt.
Credentials sit at three layers: the StackOne MCP Databricks App (OAuth on the app config, controlled by Databricks workspace admins via Unity Catalog permissions), SaaS connector credentials (server-side in your StackOne dashboard), and per-user OAuth or session tokens (server-side, scoped per user). StackOne stores OAuth tokens and API keys, refreshes them automatically, and only exposes the actions you've authorized to the agent.
Skip the StackOne MCP gateway when any of these is true:
  • Databricks's 6 first-party data-vendor MCP partners (You.com, Glean, S&P Global, FactSet, D&B, Moody's) already cover your apps
  • You use only a handful of actions across a few apps
  • You don't need multi-tenancy or per-action scoping
  • Prompt injection isn't a concern
  • Your provider already does tool discovery and server-side execution
