What is Harden
Harden is a free, local security layer for AI coding agents. Its post-trained model evaluates tool calls before they execute, using request and session context, while keeping repository code and tool output on the user's machine.
Key Features
Checks AI agent tool calls before they run
Post-trained model specialized for agent security
Runs locally, keeping repos and tool output on the machine
Uses request and session context for evaluation
Free to use
Use Cases
- Reviewing tool calls from AI coding agents before execution
- Adding a security layer to local AI-assisted development workflows
- Protecting repositories when using autonomous coding agents
Why do startups need this tool?
Startups adopting AI coding agents can use Harden to add a local security checkpoint over agent tool calls without sending code off-machine, helping teams ship with agent-driven development more confidently.
