Get information about a specific block
AI agents call getBlock 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 data without modifying state, creating obligations, or triggering external actions. It is a straightforward read operation that retrieves immutable historical block information from the Algorand blockchain. The blast radius is minimal as misuse cannot result in data corruption, financial loss, or system compromise.
From the tool's definition Tool name 'getBlock' combined with description 'Get information about a specific block' indicates a retrieval operation with no side effects.
Attacks that exploit this kind of access
Get information about a specific 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 getBlock: 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.
getBlock 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 getBlock 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 getBlock. 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.
getBlock 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.
