Get current component filters
AI agents call get_component_filters 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 only queries and returns the current component filters used in React DevTools. It performs no mutations, executions, or destructive actions. The read-only nature and low blast radius (retrieving configuration data) warrant the Read category and low severity classification.
From the tool's definition Tool name is 'get_component_filters' and description states 'Get current component filters' — a pure read operation that retrieves filter configuration without modifying state or triggering side effects.
Attacks that exploit this kind of access
Get current component filters. 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_component_filters: 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_component_filters 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_component_filters 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_component_filters. 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_component_filters 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.
