Extracts design DNA from an existing screen — colors, typography, spacing, layout patterns, and component styles. Use this to maintain visual consistency across multiple screens.
AI agents call extract_design_context to retrieve information from Stitch MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves design attributes from existing screens to inform consistency decisions. It performs analysis and extraction of visual metadata without creating, modifying, deleting, or executing external operations. The purpose is informational—enabling designers to understand and maintain consistency—which is characteristic of Read operations.
From the tool's definition The tool 'extracts' design context (colors, typography, spacing, layout patterns, component styles) from an existing screen.
Attacks that exploit this kind of access
Extracts design DNA from an existing screen — colors, typography, spacing, layout patterns, and component styles. Use this to maintain visual consistency across multiple screens. It is categorised as a Read tool in the Stitch MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Stitch MCP Server MCP server in PolicyLayer and add a rule for extract_design_context: 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 Stitch MCP Server. Nothing to install.
extract_design_context 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 extract_design_context 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 extract_design_context. 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.
extract_design_context is provided by the Stitch MCP Server MCP server (oogleyskr/stitch-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
