This release introduces enhanced security capabilities with sensitive data detection for tool calls.
New Features
- Sensitive Data Detection (Spec 026): MCPProxy now automatically scans tool call parameters for sensitive information before execution. The system detects and flags potential secrets, API keys, passwords, tokens, and other sensitive data patterns, helping prevent accidental exposure of confidential information when interacting with MCP servers. This adds an additional security layer to the existing quarantine features.
