[VibeDefend] MCP Security Proxy

VibeDefend sits as a proxy between your coding agents and the MCP servers they connect to, and inspects the traffic in real time, with no change needed on the servers themselves.
Known threats: MCP servers reported as malicious in the OSV database or in CybeDefend’s own threat intelligence database are blocked automatically, before your agent can connect to them.
Phase 1, tool descriptions: every tool exposed by a server is analyzed before the agent sees it, to detect tool poisoning (hidden instructions in descriptions or parameter schemas), tool name shadowing across servers, and descriptions that change after being approved (rug pulls).
Phase 2, tool responses: outputs returned to the agent are inspected for indirect prompt injection, instruction override attempts and sensitive data leakage.
Suspicious tools and responses are blocked or sanitized, and every event is logged for review.
