Prompt Guard Injection Sanitizer

Prompt Guard Injection Sanitizer Skill for Autonomous Agents

MCP Compatible Python 3.9+ License: MIT Zero External Dependencies

Enterprise-grade defensive input firewall for LLM autonomous agents. Inspects, filters, and neutralizes prompt injections, indirect jailbreaks, and instructions override exploits before passing untrusted text into prompts.

Key Features

  • Exploit & Jailbreak Detection: Flags attempts to override system prompts or bypass ethical boundary instructions.

  • Neutralization: Replaces hostile command sequences with safe sanitized placeholders.

  • Zero Overhead: Blazing fast regex and heuristic matching using the Python Standard Library.

    Lets MCP-compatible assistants vet inbound prompts and untrusted text for instruction-override manipulation, separator escapes, and concealed encodings before processing them. Additional inline controls cover spending limits, repetitive-plan interruption, unsafe host-action denial, and output sanitization without third-party libraries.
