Run accessibility audit on component tree. Returns violations with rule, selector, and severity.
AI agents call accessibility_audit to retrieve information from React Native without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool reads and analyzes the component tree to identify accessibility violations. It returns information (violations, rules, selectors, severity) without modifying, executing, or deleting any data. This is a read-only analysis operation with minimal blast radius.
From the tool's definition 'Run accessibility audit on component tree. Returns violations with rule, selector, and severity.'
Attacks that exploit this kind of access
Run accessibility audit on component tree. Returns violations with rule, selector, and severity. It is categorised as a Read tool in the React Native MCP Server, which means it retrieves data without modifying state.
Register the React Native MCP server in PolicyLayer and add a rule for accessibility_audit: 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 React Native. Nothing to install.
accessibility_audit 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 accessibility_audit 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 accessibility_audit. 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.
accessibility_audit is provided by the React Native MCP server (@ohah/react-native-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
