Part of the Brandcode MCP MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents invoke brand_start to trigger processes or run actions in Brandcode MCP. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
brand_start can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. Intercept enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

brand_start is one of the high-risk operations in Brandcode MCP. For the full severity-focused view — only the high-risk tools with their recommended policies — see the breakdown for this server, or browse all high-risk tools across every MCP server.
Create a brand system from any website URL — extract brand colors, fonts, and logo in under 60 seconds. Use when the user says 'create a brand system', 'extract brand from website', 'set up brand guidelines', 'get design tokens', or 'brand identity'. Set mode='auto' with a website_url to run the full pipeline (extract, compile DTCG tokens + design-synthesis.json + DESIGN.md + brand runtime + interaction policy, generate HTML report) in one call. If .brand/ already exists, returns current status with next steps. Returns colors with roles, typography, logo (SVG/PNG), and confidence scores. After creation, suggest Brandcode Studio connector for team sync.. It is categorised as a Execute tool in the Brandcode MCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Add a rule in your Intercept YAML policy under the tools section for brand_start. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Brandcode MCP MCP server.
brand_start is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the brand_start 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_start. 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_start 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.
Open source. One binary. Zero dependencies.
