Part of the Brandcode MCP MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents invoke brand_build_personas 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_build_personas 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_build_personas 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.
Build buyer personas through a guided 7-question interview — role, core tension, objections, information needs per journey stage, narrative emphasis, preferred channels, and decision authority. Mode 'interview' returns structured questions for agent-guided conversation. Mode 'record' saves a persona to strategy.yaml (auto-generates ID like PER-001, accepts JSON or freeform text via parseAnswers). Mode 'list' shows all personas with status. Writes to .brand/strategy.yaml. Bumps session counter to 4 on first write. Most brands need 3-5 personas. Part of Session 4 (content strategy). Use when the user says 'define personas', 'who is our audience', or 'start Session 4'. NOT for defining voice — use brand_compile_messaging (Session 3). Returns persona data and total count.. 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_build_personas. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Brandcode MCP MCP server.
brand_build_personas 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_build_personas 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_build_personas. 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_build_personas 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.
