Semantically search for requests that occurred within a page URL. Returns the top 10 results.
AI agents call semantic_search_requests to retrieve information from Puppeteer MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves historical request data from browser activity. It performs a passive search without creating, modifying, deleting, or executing any operations. The 'semantic search' aspect indicates filtering/searching existing data rather than triggering new actions. Belongs in the Read category as it has no side effects beyond data retrieval.
From the tool's definition Tool description states it 'semantically search[es] for requests' and 'Returns the top 10 results' — purely a retrieval and query operation with no modification or side effects.
Attacks that exploit this kind of access
Semantically search for requests that occurred within a page URL. Returns the top 10 results. It is categorised as a Read tool in the Puppeteer MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Puppeteer MCP Server MCP server in PolicyLayer and add a rule for semantic_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 Puppeteer MCP Server. Nothing to install.
semantic_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 semantic_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 semantic_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.
semantic_search_requests is provided by the Puppeteer MCP Server MCP server (jwaldor/mcp-scrape-copilot). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
