Legge localStorage/sessionStorage
AI agents call get_storage to retrieve information from DOM Analyzer MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves browser storage data (localStorage/sessionStorage) with no side effects. It performs a read-only query of existing data. While the retrieved data may be sensitive (e.g., auth tokens, user preferences), the tool itself does not modify, delete, or execute operations—it only inspects.
From the tool's definition Tool name is 'get_storage' and description states 'Legge localStorage/sessionStorage' (read localStorage/sessionStorage). The verb 'legge' (Italian for 'read') and the getter pattern confirm retrieval of stored client-side data without modification.
Attacks that exploit this kind of access
Legge localStorage/sessionStorage. It is categorised as a Read tool in the DOM Analyzer MCP Server MCP Server, which means it retrieves data without modifying state.
Register the DOM Analyzer MCP Server MCP server in PolicyLayer and add a rule for get_storage: 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 DOM Analyzer MCP Server. Nothing to install.
get_storage 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 get_storage 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 get_storage. 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.
get_storage is provided by the DOM Analyzer MCP Server MCP server (sudo-elia/dom-analyzer-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
get_storage is one line of DOM Analyzer MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
