Real-time news search. Returns recent news articles (title, url, snippet, published date)
AI agents call news_search to retrieve information from Superhighway 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 news data with read-only semantics. Although the server implements a pay-per-search microtransaction system (financial infrastructure), the tool itself only performs information retrieval. The financial transaction is a payment mechanism for access, not an action this tool performs.
From the tool's definition Tool returns news articles with metadata (title, url, snippet, published date). No modification, deletion, or code execution. The description explicitly states it 'Returns' data with no indication of side effects.
Attacks that exploit this kind of access
Real-time news search. Returns recent news articles (title, url, snippet, published date). It is categorised as a Read tool in the Superhighway MCP Server, which means it retrieves data without modifying state.
Register the Superhighway MCP server in PolicyLayer and add a rule for news_search: 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 Superhighway. Nothing to install.
news_search 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 news_search 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 news_search. 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.
news_search is provided by the Superhighway MCP server (patwalls/superhighway-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
