Part of the Brandcode MCP MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use brand_write 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_write repeatedly, creating or modifying resources faster than any human could review. Intercept'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.

Other tools in the Write risk category across the catalogue. The same policy patterns (rate-limit, validate) apply to each.
Generate on-brand content — load full brand context (colors, typography, logo, voice, strategy) before creating any branded output. Use when asked 'generate on-brand content', 'write something in our brand voice', 'load brand context for writing', or before creating social graphics, web pages, blog posts, emails, presentations, or data viz. Specify content_type for the right mix of visual and voice rules. Does NOT generate content itself — provides the creation brief so you can generate on-brand. Run brand_preflight on output afterward. Returns a structured creation brief with all brand layers.. 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.
Add a rule in your Intercept YAML policy under the tools section for brand_write. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Brandcode MCP MCP server.
brand_write 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_write rule in your Intercept 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 Intercept policy for brand_write. 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_write is provided by the Brandcode MCP MCP server (@brandsystem/mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
