WHAT IT DOES

What identity_set_uri does on Aibtc

AI agents use identity_set_uri to create or update resources in Aibtc, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Aibtc environment.

RISK

Why identity_set_uri is rated Medium

This tool modifies identity metadata (URI field) in a blockchain registry, which is a reversible write operation. While it affects identity records on a blockchain, it does not delete data (not Destructive), execute arbitrary code (not Execute), move funds (not Financial), or involve read-only operations (not Read).

From the tool's definition Tool description states 'Update the URI for an agent identity in the ERC-8004 identity registry' — 'Update' indicates modification of existing data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs identity_set_uri safely

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

identity_set_uri Rate-limited

identity_set_uri stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

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

FAQ

Questions about identity_set_uri

What does the identity_set_uri tool do? +

Update the URI for an agent identity in the ERC-8004 identity registry. It is categorised as a Write tool in the Aibtc MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on identity_set_uri? +

Register the Aibtc MCP server in PolicyLayer and add a rule for identity_set_uri: 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 Aibtc. Nothing to install.

What risk level is identity_set_uri? +

identity_set_uri is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit identity_set_uri? +

Yes. Add a rate_limit block to the identity_set_uri 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.

How do I block identity_set_uri completely? +

Set action: deny in the PolicyLayer policy for identity_set_uri. 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.

What MCP server provides identity_set_uri? +

identity_set_uri is provided by the Aibtc MCP server (aibtcdev/aibtc-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
