Frequently Asked Questions
Asked by AI teams, answered by us.
How does Stack Internal keep knowledge up-to-date?
The platform acts as a curation engine, automatically ingesting and storing knowledge with trust built in. The trust engine is constantly evaluating if that knowledge is reliable, current, authoritative, and safe to use. With automatic SME validation only when there’s critical gaps.
What is the MCP server?
The MCP server connects AI assistants and coding agents, like Claude and Cursor, to your trusted Stack Internal knowledge and can read from Stack Internal without breaking focus.
How does Stack Internal import existing knowledge?
Stack Internal brings in knowledge from wherever your team already works. We have out-of-the-box connectors for Stack Internal Community, GitHub, Google Docs, Slack and Microsoft Teams, as well as an ingestion API that can ingest critical context from any tool.
How does Stack Internal integrate with existing tools?
Stack Internal works wherever your team does. With connectors, custom integrations, and AI tool & agent support, we’ve got you covered. See Integrations for more.
How does Stack Internal identify Subject Matter Experts?
SME auto-detection stays accurate as your organization interacts with the platform over time and surfaces the right expert to the right topic. You also have the power to manually manage experts. The platform does the heavy-lifting for you, but it’s nice to have the option to adjust when you need to.
