AI agents call brand_extract_web 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_web 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 colors, fonts, and logo from any website URL — get brand identity from a live site. Use when asked 'extract brand from URL', 'get brand colors from website', 'scan my site', or when the user provides a website URL. Parses HTML for logo candidates (SVG, img, favicons, Clearbit fallback) and CSS for colors and font-family declarations. Confidence-scores everything. Pass logo_url to fetch a specific logo directly. Returns colors with roles, fonts with frequency, logo preview data, and extraction quality score.. It is categorised as a Read tool in the Brandcode MCP MCP Server, which means it retrieves data without modifying state.
Register the Brandcode MCP server in PolicyLayer and add a rule for brand_extract_web: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Brandcode MCP. Nothing to install.
brand_extract_web 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_web rule in your PolicyLayer 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 PolicyLayer policy for brand_extract_web. 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_web is provided by the Brandcode MCP server (@brandsystem/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
