Get current epoch, checkpoint, and network statistics via GraphQL
AI agents call iota_epoch_info to retrieve information from Iota Agent without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries blockchain network statistics and state information through GraphQL. It retrieves data (current epoch number, checkpoint information, and network stats) with no side effects, no state modification, and no execution of code or commands.
From the tool's definition Tool description states 'Get current epoch, checkpoint, and network statistics via GraphQL' - these are read-only queries that retrieve blockchain state information without modifying or executing anything.
Documented attack patterns abuse exactly the kind of access iota_epoch_info gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Iota Agent, and nothing reaches the server without passing your rules. This is the rule we recommend for iota_epoch_info:
{
"version": "1",
"default": "deny",
"tools": {
"iota_epoch_info": {}
}
}iota_epoch_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get current epoch, checkpoint, and network statistics via GraphQL. It is categorised as a Read tool in the Iota Agent MCP Server, which means it retrieves data without modifying state.
Register the Iota Agent MCP server in PolicyLayer and add a rule for iota_epoch_info: 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 Iota Agent. Nothing to install.
iota_epoch_info 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 iota_epoch_info 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 iota_epoch_info. 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.
iota_epoch_info is provided by the Iota Agent MCP server (scottcjn/iota-agent-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
