Bulwark MCP

Bulwark is an open-source governance layer for AI agents that acts as an MCP gateway or HTTP forward proxy. It enforces YAML-based policies, manages credentials by injecting them at the last mile, inspects content for secrets and PII, and maintains tamper-evident audit logs. It supports rate limiting and cost tracking for agents like Claude Code or OpenClaw.
