Suprawall Mcp

This is the MCP implementation of SupraWall, a deterministic security layer that sits between Claude and your tools to enforce guardrails before actions execute. It scans for prompt injection attacks, scrubs PII from requests, and blocks tool calls that violate your policies. The approach is rule-based rather than LLM-based, so you get consistent enforcement instead of probabilistic filtering. You'd reach for this when you're running agents with access to production systems and need forensic-grade logs plus hard stops on risky operations. The broader SupraWall ecosystem includes integrations for AutoGen, CrewAI, LangChain, and other frameworks, but this package specifically implements the stdio-based MCP protocol for Claude Desktop and similar environments.
