Search publicly accessible objects. No authentication required.
AI agents call dual_public_search_objects to retrieve information from DUAL 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 data from publicly accessible objects without requiring credentials, which is the defining characteristic of a Read operation. The lack of authentication and public scope limits potential blast radius. On a blockchain system with sensitive objects, severity could be slightly elevated, but the public accessibility and read-only nature keep this at low risk.
From the tool's definition Tool name 'dual_public_search_objects' and description 'Search publicly accessible objects. No authentication required.' indicate a query/search operation with no side effects or authentication barrier.
Attacks that exploit this kind of access
Search publicly accessible objects. No authentication required. It is categorised as a Read tool in the DUAL MCP Server MCP Server, which means it retrieves data without modifying state.
Register the DUAL MCP Server MCP server in PolicyLayer and add a rule for dual_public_search_objects: 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 DUAL MCP Server. Nothing to install.
dual_public_search_objects 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 dual_public_search_objects 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 dual_public_search_objects. 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.
dual_public_search_objects is provided by the DUAL MCP Server MCP server (ro-ro-b/dual-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
