Tools & Permissions
All Claude Code tools are disabled by default. Learn how to selectively enable them and what each one does.
Default Behaviour
All Claude Code tools are disabled by default. This is intentional — it prevents potentially harmful operations (like file writes or shell commands) from running automatically the first time you open a session.
You need to explicitly enable the tools you want to use.
Enabling Tools
- Click the gear icon in the sidebar to open Tools Settings
- Toggle on the tools you need
- Your preferences are saved locally and persist across sessions
Recommended approach: Start with read-only tools enabled and add write/execute permissions only when you need them.
Available Tool Categories
| Tool | What it does | Risk level |
|---|---|---|
Read | Read file contents | Low |
Glob / Grep / LS | Search and list files | Low |
Edit / MultiEdit / Write | Modify and create files | Medium |
Bash | Run shell commands | High |
Bash(git log:*) | Scoped bash — git log only | Low |
WebFetch / WebSearch | Access the web | Medium |
Task | Spawn sub-agents | Medium |
Scoped Bash Permissions
Rather than enabling all Bash commands, you can scope permissions to specific commands:
{
"permissions": {
"allow": [
"Bash(npm run lint)",
"Bash(npm run test *)",
"Bash(git log:*)"
],
"deny": [
"Bash(curl *)",
"Read(./.env)"
]
}
}This is written to your ~/.claude/settings.json and takes effect immediately in both CloudCLI UI and the Claude Code CLI.
How Settings Sync
Permission changes you make in CloudCLI UI are written directly to your local ~/.claude config. This means:
- Changes appear immediately in your Claude Code CLI sessions
- MCP servers you add via the UI show up when you run
claudein your terminal - There is no separate config to maintain
Project-Scoped vs Global Permissions
Settings can be scoped at two levels:
- Global (
~/.claude/settings.json) — applies to all projects - Project (
.claude/settings.jsonin the project root) — overrides global for that project only
Project-scoped settings can be committed to your repo so teammates share the same tool configuration. If you're working with a team, shared cloud environments for teams let you distribute MCP servers, tool permissions, and context files to every developer automatically.
