Image search. Returns direct image URLs, source pages, and thumbnails as JSON from a
AI agents call image_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.
Image search is a read-only query operation that retrieves and displays existing publicly available image data. While the server uses USDC microtransactions, those are payment mechanics separate from this tool's function. The tool itself does not write, delete, execute code, or create financial obligations—it only fetches and returns search results.
From the tool's definition Tool performs image search and returns URLs, source pages, and thumbnails without modifying any data. The description explicitly states it 'Returns' results, indicating a retrieval operation with no side effects.

Image search. Returns direct image URLs, source pages, and thumbnails as JSON from a. 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 image_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.
image_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 image_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 image_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.
image_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.
