Count objects matching filter criteria without returning the full objects.
AI agents call dual_count_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.
The tool performs a read-only aggregation operation (counting) on filtered data. It returns no side effects, does not modify state, and poses minimal risk if misused by an AI agent. Even in the context of a Web3 system, counting objects is a harmless informational query.
From the tool's definition Tool name and description: 'Count objects matching filter criteria without returning the full objects.' This is a query/count operation that retrieves aggregate metadata about existing objects without modification, deletion, or execution of external…
Attacks that exploit this kind of access
Count objects matching filter criteria without returning the full objects. 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_count_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_count_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_count_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_count_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_count_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.
dual_count_objects is one line of DUAL MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
