Search requests with advanced filtering
AI agents call search_requests to retrieve information from Fastly NGWAF MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries request data using filters, returning results without creating, modifying, or deleting any resources. It has no capacity to alter system state, trigger external operations, or commit financial actions. The low severity reflects the minimal risk of data exposure through search queries in a WAF context, where request logs are typically non-sensitive operational data.
From the tool's definition Tool name 'search_requests' and description 'Search requests with advanced filtering' indicate data retrieval with no modification. The verb 'search' and 'filtering' are characteristic of read operations that query existing data without side effects.
Attacks that exploit this kind of access
Search requests with advanced filtering. It is categorised as a Read tool in the Fastly NGWAF MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Fastly NGWAF MCP Server MCP server in PolicyLayer and add a rule for search_requests: 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 Fastly NGWAF MCP Server. Nothing to install.
search_requests 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 search_requests 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 search_requests. 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.
search_requests is provided by the Fastly NGWAF MCP Server MCP server (purpleax/fastlymcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
