AI agents call get_navigation_history to retrieve information from React Tools without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries navigation history data without creating, modifying, deleting, executing code, or committing financial obligations. It is a straightforward read operation that returns existing information about user navigation patterns. The low severity reflects minimal blast radius—misuse would expose historical navigation patterns but cannot directly harm systems or data.
From the tool's definition Tool name 'get_navigation_history' and description 'Get user navigation history' indicate retrieval of historical data with no modification or side effects.
Documented attack patterns abuse exactly the kind of access get_navigation_history gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and React Tools, and nothing reaches the server without passing your rules. This is the rule we recommend for get_navigation_history:
{
"version": "1",
"default": "deny",
"tools": {
"get_navigation_history": {}
}
} get_navigation_history is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get user navigation history. It is categorised as a Read tool in the React Tools MCP Server, which means it retrieves data without modifying state.
Register the React Tools MCP server in PolicyLayer and add a rule for get_navigation_history: 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 Tools. Nothing to install.
get_navigation_history 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_navigation_history 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_navigation_history. 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_navigation_history is provided by the React Tools MCP server (mcp-fe/mcp-fe). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from React Tools, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
