Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@DiagBridge MCPdiagnose my Windows computer's network issues"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
DiagBridge MCP
DiagBridge MCP is a general Windows MCP bridge for trusted local and remote AI agents.
It exposes one shared tool registry through:
stdiofor local MCP clients (Codex, Claude Code, Cursor, etc.)Streamable HTTPfor remote MCP clients (ChatGPT, Codex Plugin, remote agents, etc.)
Runtime Requirements: Requires Node.js 22.6 or newer. Tested on Node.js 24.
中文：
DiagBridge MCP 是面向可信本地和远程 AI Agent 的通用 Windows MCP 桥。 它通过 stdio 和 Streamable HTTP 暴露同一套工具。
Transports
Entry point | Command / Script | Purpose |

Tools Overview
All tools are defined in a single, shared tool registry (src/mcp/tool-registry.ts).
Local Stdio Defaults (6 read-only tools)
system_infolist_dirread_filedrive_inventoryjunk_candidateswindows_event_summary
write_file and run_command are destructive and disabled by default. They can be enabled for stdio using DIAGBRIDGE_MCP_TOOLS.
Remote Streamable HTTP Defaults (4 read-only tools)
system_infodrive_inventoryjunk_candidateswindows_event_summary
read_file, write_file, and run_command are never registered on the remote transport for security and privacy protection.
For full tool details, see docs/TOOLS.md.
