Analyze a page
AI agents call analyze_structure to retrieve information from aria51 MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool analyzes page structure for accessibility compliance, which is purely informational. It retrieves and examines data (DOM structure, WCAG compliance metadata) without creating, modifying, deleting, or executing code. This fits the 'Read' category of querying/inspecting data with no side effects.
From the tool's definition Tool name 'analyze_structure' paired with description 'Analyze a page' indicates data retrieval and inspection. Server context confirms this is an accessibility auditing tool that scans and detects violations without modifying content.

Analyze a page. It is categorised as a Read tool in the aria51 MCP Server MCP Server, which means it retrieves data without modifying state.
Register the aria51 MCP Server MCP server in PolicyLayer and add a rule for analyze_structure: 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 aria51 MCP Server. Nothing to install.
analyze_structure 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 analyze_structure 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 analyze_structure. 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.
analyze_structure is provided by the aria51 MCP Server MCP server (justinleeirizarry/aria51). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
