WHAT IT DOES

What getBlock does on Agentek Eth

AI agents call getBlock to retrieve information from Agentek Eth without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why getBlock is rated Low

This tool retrieves blockchain data (block metadata) with no side effects, modifications, or ability to execute transactions. It is a straightforward read-only query operation. The low severity reflects that misuse only exposes public blockchain information.

From the tool's definition Tool description states 'Get information about a block including timestamp, transactions, gas used, etc.' — purely informational retrieval with no modification or execution capability.

RECOMMENDED RULE

The rule that runs getBlock safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Agentek Eth, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For getBlock, this is the rule to start with:

getBlock Allowed

getBlock is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  "default": "deny",
  "tools": {
    "getBlock": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Agentek Eth, apply this rule, and every getBlock call is checked against it from then on.
