Get native style and layout info (React Native only)
AI agents call get_native_style to retrieve information from React Devtools without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves styling and layout information from a React Native application for inspection and debugging purposes. It has no side effects—it does not create, modify, delete, or execute operations. It is purely a read operation querying application metadata, consistent with other inspection tools on this debugging server like 'get_component_tree' and 'get_connection_status'.
From the tool's definition Tool name 'get_native_style' and description 'Get native style and layout info' indicate a retrieval operation.
Attacks that exploit this kind of access
Get native style and layout info (React Native only). It is categorised as a Read tool in the React Devtools MCP Server, which means it retrieves data without modifying state.
Register the React Devtools MCP server in PolicyLayer and add a rule for get_native_style: 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 Devtools. Nothing to install.
get_native_style 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_native_style 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_native_style. 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_native_style is provided by the React Devtools MCP server (skylarbarrera/react-devtools-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
