- Sessions + keyboard shortcuts merged into one compact section
- MCP section reduced to card links — power users click through

-### Keep Conversations Organized
-
-Sessions let you separate work by topic — one for your tax documents, another for a code review, a third for research. You can:
-
-- **Create** a new session from the sidebar
-- **Rename** sessions by clicking the title
-- **Search** across all sessions with `Ctrl+K`
-- **Export** as Markdown or JSON
-- **Delete** with confirmation
-
-Sessions sync between the CLI (`gaia chat`) and the Agent UI — start in one, pick up in the other.
-
-### Extend with External Tools (MCP)
-
-Connect external MCP servers to give the agent access to GitHub, Slack, databases, and more:
-
-```bash
-gaia mcp add time "uvx mcp-server-time"
-```
-
-Or expose the Agent UI itself as an MCP server — letting Claude Code, Cursor, or any MCP client drive GAIA agents programmatically. Conversations appear in the UI in real time.

+## Sessions and Shortcuts

+Sessions let you organize conversations by topic. They sync between the CLI (`gaia chat`) and the Agent UI — start in one, pick up in the other. Export any session as Markdown or JSON from the session menu.
 
 | Shortcut | Action |
 |----------|--------|
 | `Enter` | Send message |
 | `Shift+Enter` | New line |
 | `Escape` | Stop agent response |
-| `Ctrl+K` | Focus sidebar search |
+| `Ctrl+K` | Search across sessions |

+## Extend with MCP
+
+The agent supports the **Model Context Protocol** in both directions — connect external tools to expand what the agent can do, or expose the Agent UI itself so other AI tools can drive it.

+  Misconfigured MCP servers can cause slow responses. If you experience timeouts, check `~/.gaia/mcp_servers.json` and remove any servers you don't need. See [Troubleshooting](#llm-response-times-out-or-fails) for details.
