Fetch on-chain object data by ID. Returns owner, type, version, and content.
AI agents call iota_object 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 retrieves and queries blockchain data without creating, modifying, deleting, or executing any operations. It is a straightforward data retrieval function operating on publicly readable blockchain state. The blast radius of misuse is minimal—an agent could only retrieve information already on-chain, with no ability to alter state or access unauthorized data beyond what the public blockchain exposes.
From the tool's definition Tool description states it 'Fetch[es] on-chain object data by ID. Returns owner, type, version, and content.' The verbs 'fetch' and 'returns' indicate read-only retrieval with no side effects.
Documented attack patterns abuse exactly the kind of access iota_object 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_object:
{
"version": "1",
"default": "deny",
"tools": {
"iota_object": {}
}
}iota_object is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Fetch on-chain object data by ID. Returns owner, type, version, and content. 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_object: 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_object 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_object 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_object. 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_object 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.
