Add MCP tools and folders to Workbench

Workbench can use folders the owner grants and MCP tool servers. Each call waits for your approval.

Grant a folder

The owner grants a folder to one person:

1. Open Toolbox · Tools → Folders · File tools → Grant an existing folder.
2. Fill in Folder name, Full folder path on Workbench’s host and Person who can use it. People appear after they sign in to Workbench once. Tick Allow creating and editing text files only if they need it.
3. Press Grant folder access.

To share a folder, grant it to each person separately. A person can also search the folder as documents: see Chat with your documents and PDFs in Workbench.

Add a tool server

• Toolbox · Tools → Add a shared network server: a Name, the MCP address, and a Bearer credential if it needs one. Press Add server.
• The owner can add a program on Workbench’s machine: Add a local server (owner only), with its Full executable path and Arguments (JSON array). Press Save local server.

Use tools in a chat

1. Open the chat’s gear, This chat’s settings, tick the servers and folders, and press Save settings.
2. Each call waits for you: Approve call or Decline.

Good to know

• Local servers and folders need a Windows service install or a Linux system install. On Linux, folder tools need Landlock ABI 3 or later.
• MCP sign-in (OAuth), resources and prompts are not supported yet.
• Tools on another of your computers: set up a Job Site.
