assemble_and_load · MCPEmulate MCP: Risk & Policy

WHAT IT DOES

What assemble_and_load does on MCPEmulate

AI agents invoke assemble_and_load to trigger actions in MCPEmulate. 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 assemble_and_load needs a policy

The tool name 'assemble_and_load' strongly implies it assembles machine code and loads it into an emulator session for execution. In the context of an MCP server providing CPU emulation, disassembly, and assembly tools, this likely converts assembly language to machine code and loads it into an emulator's memory — which constitutes executing or staging code execution.

From the tool's definition Tool name 'assemble_and_load' in context of a CPU emulation server with tools like 'assemble', 'create_emulator', and 'execute' capabilities.
