Initialize a .brand/ directory with empty config scaffold. Low-level tool — prefer brand_start instead, which calls this automatically and also presents extraction options. Only use brand_init directly if you need to set up the directory without running extraction. Returns list of created files.

AI agents use brand_init to create or modify resources in Brandcode MCP. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.
Without a policy, an AI agent could call brand_init repeatedly, creating or modifying resources faster than any human could review. PolicyLayer's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Brandcode MCP.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

These attack patterns abuse exactly the kind of access brand_init gives an agent. Each links to the full case and the policy that stops it:
Other write tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Initialize a .brand/ directory with empty config scaffold. Low-level tool — prefer brand_start instead, which calls this automatically and also presents extraction options. Only use brand_init directly if you need to set up the directory without running extraction. Returns list of created files.. It is categorised as a Write tool in the Brandcode MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Brandcode MCP server in PolicyLayer and add a rule for brand_init: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Brandcode MCP. Nothing to install.
brand_init is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the brand_init rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for brand_init. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
brand_init is provided by the Brandcode MCP server (@brandsystem/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
