Single-target operation
Part of the Brandcode MCP MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents use brand_generate_designmd 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_generate_designmd 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.

Agents calling write-class tools like brand_generate_designmd have been implicated in these attack patterns. Read the full case and prevention policy for each:
Other tools in the Write risk category across the catalogue. The same policy patterns (rate-limit, validate) apply to each.
Generate DESIGN.md (portable agent-facing design brief) and design-synthesis.json (structured radius, shadow, spacing, layout, motion, component, and personality signals) from the current brand system. Reads extraction-evidence.json when available for grounded visual signals; falls back to core-identity.yaml and tokens.json after manual edits. Use after brand_extract_site or brand_extract_visual to synthesize multi-page evidence into a single design brief. Use after brand_compile if evidence is unavailable. Returns file paths and synthesis source used. Read-only except for writing the two output files. NOT for extracting brand identity — use brand_extract_web or brand_extract_visual first.. 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_generate_designmd. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Brandcode MCP MCP server.
brand_generate_designmd 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_generate_designmd 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_generate_designmd. 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_generate_designmd 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.
