Part of the Brandcode MCP MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents call brand_extract_figma to retrieve information from Brandcode MCP without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though brand_extract_figma only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Extract brand identity from a Figma design file. Accepts multiple input formats: variable_map (simple { name: hex } from get_variable_defs), design_context (raw get_design_context output with colors/fonts parsed from code), variables (structured array), styles (text styles), and logo_svg. Two phases: mode='plan' returns which Figma MCP tools to call. Mode='ingest' processes all collected data. Figma values override web extraction based on source_priority. Also accepts figma_url for automatic file key extraction. NOT for web extraction (use brand_extract_web).. It is categorised as a Read tool in the Brandcode MCP MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for brand_extract_figma. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Brandcode MCP MCP server.
brand_extract_figma is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the brand_extract_figma 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_extract_figma. 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_extract_figma 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.
