**Private beta**

Business Knowledge is in private beta. If **Business Knowledge** isn't in your PostHog sidebar, your project isn't in the beta yet. [Send feedback in the app](https://app.posthog.com/#panel=support%3Afeedback%3A%3Alow%3Atrue).

PostHog AI, Support, and MCP clients all read the same sources. A source is used only once it's [ready](https://posthog.com/docs/business-knowledge/ai-data-processing.md).

## PostHog AI

[PostHog AI](https://posthog.com/docs/posthog-ai.md) searches your sources when a question is about your own product, policies, or team. Questions about PostHog itself still go to the PostHog docs.

Answers cite the source name, so you can see where a fact came from. When one passage isn't enough, PostHog AI reads more of the document around it.

## Support

The Support [AI agent](https://posthog.com/docs/support/ai-agent.md) drafts ticket replies from your sources. You can't turn it on until at least one source is ready.

[Learn from support](https://posthog.com/docs/business-knowledge/learn-from-support.md) works the other way: your team's replies to resolved tickets become new sources.

## MCP

The [PostHog MCP server](https://posthog.com/docs/model-context-protocol.md) gives any MCP client tools to search and manage your sources. It tells agents to check Business Knowledge before they answer a question about your company.

| Scope | What the tools do |
| --- | --- |
| `business_knowledge:read` | Search sources, read the text around a match, get sources and libraries, and search or read files in selected GitHub repositories |
| `business_knowledge:write` | Add text and URL sources, update a source, and create, update, or delete libraries |

Upload files and delete sources in PostHog. MCP can't do either. See the [MCP tools reference](https://posthog.com/docs/model-context-protocol/tools.md) for each tool.
