Permissions ​

By default, Crush will ask you for permission before running tool calls.

Allowing Tools ​

If you'd like, you can allow tools to be executed without prompting you for permissions. Use this with care.

bash
permissions allow view ls grep edit mcp_context7_get-library-doc

Disabling Built-In Tools ​

You can also deny tools, hiding then from the agent entirely:

bash
permissions deny bash sourcegraph

To disable tools from MCP servers, see the MCP config.

You only live once ​

You can also skip all permission prompts completely by running Crush with the --yolo flag. Be very, very careful with this feature.
