What is prompt injection in MCP tools?

It's hiding malicious instructions in tool descriptions, tricking agents into bad actions like data leaks.

How do I install and use asqav-mcp?

`pip install asqav-mcp`, then call `scan_tool_definition()` or `scan_all_tools()`. Fully local.

Does scanning add latency to agent calls?

Nope — zero overhead. Scan once at registration, not per-call.

What If Your AI Agent's Tools Are Whispering Betrayal?

Imagine your AI agent calling a 'harmless' weather tool that secretly phones home with your data. asqav-mcp's scanner catches these MCP tool traps before they spring.
