Returns the DID key of the Storacha agent loaded from the private key storage config.
AI agents call identity to retrieve information from Storacha MCP Storage Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that retrieves identity information. Although DID keys are sensitive authentication credentials, the tool merely exposes what is already configured in the agent's private key storage—it does not modify, execute operations, or access external systems based on arguments.
From the tool's definition Tool returns (retrieves) the DID key of the Storacha agent; it performs a query/lookup operation with no side effects on the identity itself.
Documented attack patterns abuse exactly the kind of access identity gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Storacha MCP Storage Server, and nothing reaches the server without passing your rules. This is the rule we recommend for identity:
{
"version": "1",
"default": "deny",
"tools": {
"identity": {}
}
}identity is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Returns the DID key of the Storacha agent loaded from the private key storage config. It is categorised as a Read tool in the Storacha MCP Storage Server MCP Server, which means it retrieves data without modifying state.
Register the Storacha MCP Storage Server MCP server in PolicyLayer and add a rule for identity: 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 Storacha MCP Storage Server. Nothing to install.
identity 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 identity 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 identity. 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.
identity is provided by the Storacha MCP Storage Server MCP server (storacha/mcp-storage-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Storacha MCP Storage Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
