Warden9
A secure runtime for AI agents. Keeps credentials out of the model context, enforces scoped access at execution time, and puts approvals and an audit trail around what an agent actually does.
Free plan (1 concurrent session); paid from $20/mo, up to $200/mo
Pros
- Credentials never enter the prompt or model context
- Approval step before an agent runs a sensitive action
- Full audit trail of agent activity
- Works with MCP, LangChain, CrewAI, VS Code and Cursor
Cons
- Aimed at developers, not general business users
- Very new, with little public track record
- Concurrent session limits bite quickly on lower plans
- Self-hosting is enterprise-only
