Parameter Sanitization And Constraint Enforcement

The security gateway for AI agents — firewall, auditor, and remote control for MCP tool calls

Unique: Operates at the MCP argument level with awareness of tool schemas, enabling type-aware validation and sanitization; supports both declarative constraints (JSON Schema) and imperative custom validators for complex rules

vs others: More precise than generic input validation because it understands tool semantics; more flexible than hardcoded validation because constraints are declarative and reusable across tools
