MCP server
The MCP server is how an AI client reaches DevHub. While it runs, a connected client can call DevHub’s tools: search a vault, read a repository index, use plans. While it is stopped, agents cannot reach DevHub.
When to use it
Section titled “When to use it”- Your client says it cannot reach DevHub.
- You want to stop all agent access for a while.
- You connect a new client and need the MCP address.
Start, stop or restart
Section titled “Start, stop or restart”The MCP server card is on the Dashboard.
- Read the status: Running, Stopped or Error. While it runs, the card also shows how long.
- Click Stop MCP to stop it, or Start MCP to start it. Restart stops it and starts it again. The tray menu has Stop MCP server too.
- If the status is Error, DevHub says “Could not start. Check the port in Settings, then start it again.” Fix the setting and start it again.
The uptime counts from the moment the server started. Stopping it, or signing out, clears it, and a restart begins at zero.
Copy the address
Section titled “Copy the address”The MCP address is not printed in these pages. Copy it from the Dashboard: the MCP server card has a Copy MCP endpoint button, and the top bar shows the same address. Paste it into the settings of your AI client, or use Set up a folder on Harnesses Manage to let DevHub write the client configuration for you. See Connect an AI client.
Choose which tools agents get
Section titled “Choose which tools agents get”Settings > MCP Server has Allowed MCP tools. A disabled tool disappears from discovery and is rejected if a client calls it directly. The Dashboard shows how many are enabled, as “N of M tools on”, and marks a group amber when part of it is disabled. The tools are listed in the catalog of DevHub tools.
Sign-in and permissions
Section titled “Sign-in and permissions”The server runs only while your session is active and your account may use it. When a session ends, the server stops serving at once and answers every request with “sign in required” until you sign in again. Since 0.8.1 each tool is also offered only when your Vartari plan allows that area for agents, at the level the tool needs. Deleting files, running scripts, starting agents and taking screenshots need the manage level. An area your account does not include stays visible but disabled, with the permission it needs.
Who is connected
Section titled “Who is connected”The Dashboard lists Connected clients seen in the last 24 hours, active now or idle. The Activity screen lists every call: who asked, the tool, the result and how long it took.
