Get JavaScript errors and exceptions from the running React Native app. Includes RedBox errors captured via console.error.
AI agents call get_errors to retrieve information from Mcp Rn Devtools without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves diagnostic information about errors that have occurred in a React Native application. It is a read-only operation that inspects and reports existing error state without modifying, executing code, deleting data, or causing financial impact.
From the tool's definition Tool description states it 'Get[s] JavaScript errors and exceptions' with no modification or execution capability. It retrieves and queries diagnostic data (RedBox errors, console.error logs) from a running app without side effects.
Attacks that exploit this kind of access
Get JavaScript errors and exceptions from the running React Native app. Includes RedBox errors captured via console.error. It is categorised as a Read tool in the Mcp Rn Devtools MCP Server, which means it retrieves data without modifying state.
Register the Mcp Rn Devtools MCP server in PolicyLayer and add a rule for get_errors: 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 Rn Devtools. Nothing to install.
get_errors 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_errors 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_errors. 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_errors is provided by the Mcp Rn Devtools MCP server (pablonortiz/mcp-rn-devtools). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
