Claude Code Guardrails

![Example Table](example.png)

`settings.json` works if:

You're fine editing JSON and killing Claude Code sessions every time policy changes
Your security team is comfortable making PRs
You don't need to know what got blocked, when, or for whom
Basic pattern matching like Bash(rm:*) covers your use cases

Use this if:

Policy changes need to apply instantly across your team—no git pull, no restart
Security/compliance needs a clear audit trail of every blocked command
You need conditional logic: "allow rm -rf on node_modules, deny everywhere else"
Non-engineers need to edit rules without touching config files

Rulebricks gives you instant governance from one hook.

Claude Code → PreToolUse hook → Rulebricks API → allow / deny / ask

Setup (5 minutes)

1. Create your rules

Go to rulebricks.com and create an account
Fork one of these templates from the "AI Agents" category:
- Claude – Bash Guardrails — control shell commands
- Claude – File Access Policy — control file read/write/edit
- MCP Tool Governance — control MCP server operations
Customize the rules for your team
Publish the rule
Copy your API key from the API tab

2. Install

**Automatically finds your rules**

git clone https://github.com/rulebricks/claude-code-guardrails
cd claude-code-guardrails
./install.sh

Claude will detect your published rules and wire up the appropriate hooks.

3. Restart Claude Code

You're done.
