## Example call (MCP tools/call, JSON-RPC 2.0)

```json

  "jsonrpc": "2.0",

## Why get_accessibility_snapshot is rated Low

This tool retrieves accessibility information about a page (snapshot implies a read of current state), analogous to other analysis tools on the server. It has no side effects on the target system. The empty description lowers confidence slightly, but the semantic context from the server purpose and sibling tools strongly suggests a read operation that queries accessibility properties for analysis purposes.

From the tool's own definition: "Tool name 'get_accessibility_snapshot' and sibling tools like 'analyze_page', 'get_dom_overview', 'get_element_details', 'get_screenshot', and 'get_tech_stack' all indicate read-only inspection capabilities."

## Use case

AI agents call get_accessibility_snapshot to retrieve information from UI Analyzer MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)
