Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| MCP_QEMU_LAB_WORKSPACE | Yes | The absolute path to the directory where mcp-qemu-lab will store its workspace, logs, and artifacts. |
Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

TDQS
Scored across 22 tools
Each tool has a clearly distinct purpose with no ambiguity, as they target specific actions on well-defined resources like VM operations, guest interactions, debugging, or process management. For example, vm_start, vm_stop, and vm_status are distinct lifecycle actions, while debugger_attach, debugger_continue, and debugger_detach are separate debugging steps.
Tool names follow a highly consistent verb_noun pattern throughout, such as vm_start, guest_copy_in, debugger_attach, and process_list. This predictability makes it easy for agents to understand and select the right tool based on its naming convention.
With 22 tools, the count is slightly high but reasonable for the comprehensive scope of QEMU lab management, covering VM lifecycle, guest operations, debugging, and process handling. It feels slightly heavy but each tool appears to earn its place without obvious redundancy.
The tool set provides complete coverage for the QEMU lab domain, including VM creation, start/stop/status, snapshot management, guest file operations, process debugging, and dependency checks. There are no apparent gaps that would hinder agent workflows, as all essential operations are supported.
