web_github_clone · PC-Control MCP Server MCP: Risk & Policy

WHAT IT DOES

What web_github_clone does on PC-Control MCP Server

AI agents invoke web_github_clone to trigger actions in PC-Control MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why web_github_clone needs a policy

Cloning a repository executes an external network operation and writes arbitrary third-party code to the local filesystem. On a Windows PC-control server that already supports shell command execution, cloning a malicious or unintended repository could introduce malware or unwanted code.

From the tool's definition Clone a GitHub repository — executes a git clone operation that downloads and materializes external code onto the local filesystem
