Lists all screens in a Stitch project.
AI agents call list_screens 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 performs a read-only operation to enumerate screens within a project. It retrieves information but does not create, modify, delete, or execute any operations. The low severity reflects minimal risk—unauthorized access would only expose design project structure, not financial data or destructive capabilities.
From the tool's definition Tool name 'list_screens' and description 'Lists all screens in a Stitch project' indicate a query operation that retrieves project data without modification or side effects.
Attacks that exploit this kind of access
Lists all screens in a Stitch project. 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 list_screens: 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.
list_screens 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 list_screens 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 list_screens. 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.
list_screens 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.
