Get information about the latest block
AI agents call getCurrentBlock to retrieve information from Algorand MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries blockchain state information (the latest block) without creating, modifying, deleting, or executing anything. It is a straightforward read operation on publicly available blockchain data. The blast radius is minimal since misuse would only retrieve information already visible on-chain.
From the tool's definition Tool name 'getCurrentBlock' and description 'Get information about the latest block' indicate a data retrieval operation with no side effects.
Attacks that exploit this kind of access
Get information about the latest block. It is categorised as a Read tool in the Algorand MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Algorand MCP Server MCP server in PolicyLayer and add a rule for getCurrentBlock: 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 Algorand MCP Server. Nothing to install.
getCurrentBlock 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 getCurrentBlock 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 getCurrentBlock. 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.
getCurrentBlock is provided by the Algorand MCP Server MCP server (tairon-ai/algorand-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
