🔌 MCP Servergautam-u
A local MCP server that scans AI chat logs for leaked API keys and secrets on macOS.
Sieve MCP is a specialized security utility for macOS that acts as a guardrail for AI-assisted development. As developers increasingly use AI coding assistants, the risk of pasting API keys or environment secrets into chat interfaces grows. Sieve MCP mitigates this by providing 9 distinct MCP tools that monitor and sanitize AI tool transcripts. Key features include a findings list with redacted previews, boolean secret detection via 'sieve_check_text', and a robust redaction engine that replaces sensitive strings with 'sieve://' placeholders. The architecture is built for privacy, utilizing local-only stdio transport and the macOS Keychain as a secure vault for secret management. It supports a wide range of platforms including Claude Code, Cursor, Copilot Chat, and Gemini CLI. By ensuring that raw secrets are never exposed to the LLM context, Sieve MCP allows developers to maintain high-velocity workflows without compromising their security posture.
