+#### Bring your own tools (MCP servers)
+
+The chat supports **MCP (Model Context Protocol) servers** — external tool
+services that let the AI do things like search marketplaces, query other
+services, or pull in specialized data. Every member can connect their own:
+
+1. In the chat, go to **Settings → Tools** (or **Admin Settings → External
+   Tools** shows admin-managed ones).
+2. Add an MCP server by its URL (it must be reachable over HTTP — servers that
+   run only locally on your own computer, like many Claude Desktop configs,
+   can't be attached here; use their hosted versions if offered).
+3. In a conversation, pick the tool server from the tools menu (the ⊕ or
+   wrench icon near the message box) and ask away.
+
+Your tool servers belong to you: they run under your account, you choose which
+conversations they attach to, and other members don't see them. Please review
+what a third-party tool service does with your data before connecting it — see
+the [privacy policy](privacy-policy.md) for how the co-op handles your side.
