Find all usages of a specific prop across JSX/React files. Use this tool when you need to: - Locate where a prop is used throughout the codebase - Find all components that use a specific prop like
AI agents call find_prop_usage to retrieve information from JSX Prop Lookup MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a static analysis tool that searches and retrieves information about prop usage in a codebase. It has no side effects, cannot modify files, execute code, or delete data. It merely reads and queries the AST to identify where specific props are referenced. This is a straightforward Read category tool with low risk.
From the tool's definition Tool performs 'Find all usages of a specific prop across JSX/React files' and 'Locate where a prop is used throughout the codebase' - both pure query/search operations that retrieve data without modifying code or triggering execution.

Find all usages of a specific prop across JSX/React files. Use this tool when you need to: - Locate where a prop is used throughout the codebase - Find all components that use a specific prop like. It is categorised as a Read tool in the JSX Prop Lookup MCP Server MCP Server, which means it retrieves data without modifying state.
Register the JSX Prop Lookup MCP Server MCP server in PolicyLayer and add a rule for find_prop_usage: 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 JSX Prop Lookup MCP Server. Nothing to install.
find_prop_usage 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 find_prop_usage 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 find_prop_usage. 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.
find_prop_usage is provided by the JSX Prop Lookup MCP Server MCP server (lmn451/jsx-prop-lookup-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
