Analyze margins, paddings, and gaps across elements to find inconsistencies and spacing scale
AI agents call get_spacing_analysis to retrieve information from Mcp Browser Lens without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool examines computed spacing properties (margins, paddings, gaps) of DOM elements to identify inconsistencies against a spacing scale. It is a read-only inspection capability with no side effects, aligning with the Read category. The blast radius if misused is minimal—the worst case is misleading analysis output.
From the tool's definition Tool name 'get_spacing_analysis' and description 'Analyze margins, paddings, and gaps across elements to find inconsistencies and spacing scale' indicate data retrieval and analysis only.
Attacks that exploit this kind of access
Analyze margins, paddings, and gaps across elements to find inconsistencies and spacing scale. It is categorised as a Read tool in the Mcp Browser Lens MCP Server, which means it retrieves data without modifying state.
Register the Mcp Browser Lens MCP server in PolicyLayer and add a rule for get_spacing_analysis: 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 Mcp Browser Lens. Nothing to install.
get_spacing_analysis 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_spacing_analysis 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_spacing_analysis. 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_spacing_analysis is provided by the Mcp Browser Lens MCP server (nano-step/mcp-browser-lens). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
