Bulwark MCP Server
Open-source governance layer for AI agents. Bulwark sits between AI agents and external tools, enforcing policies, managing credentials, inspecting content, and maintaining a complete audit trail. One policy governs all your agents - Claude Code, OpenClaw, Codex, or any MCP/HTTP client.
People who work with Bulwark and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Rust.
