List ZK-rollup checkpoints. Each checkpoint contains a state root and proof that anchors batches to L1.
AI agents call dual_list_checkpoints 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 and queries ZK-rollup checkpoint data containing state roots and proofs. It performs no mutations, deletions, financial transactions, or code execution. The blast radius of misuse is minimal—an AI agent can only view existing checkpoint information, which is typically public blockchain data. Thus it is classified as Read with low severity.
From the tool's definition The tool name 'dual_list_checkpoints' and description 'List ZK-rollup checkpoints' clearly indicate a retrieval operation. The phrase 'List' combined with 'checkpoints' (read-only query of blockchain state data) confirms no side effects or modifications occur.

List ZK-rollup checkpoints. Each checkpoint contains a state root and proof that anchors batches to L1. 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_list_checkpoints: 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_list_checkpoints 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_list_checkpoints 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_list_checkpoints. 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_list_checkpoints 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.
