WHAT IT DOES

What interop_resolve does on Dual Registry

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

Parameter	Type	Required	Description
`q`	string	—	Capability query
`tool`	string	—
`limit`	number	—
`skill`	string	—
`prefer`	string	—
`listing_id`	string	—

Parameters from the server's own tool schema.

RISK

Why interop_resolve is rated Medium

An AI agent can call interop_resolve faster than any human can review: one bad instruction and it creates or modifies resources in Dual Registry by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs interop_resolve safely

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

interop_resolve Rate-limited

interop_resolve 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 Dual Registry, apply this rule, and every interop_resolve call is checked against it from then on.

How do I enforce a policy on interop_resolve? +

Register the Dual Registry MCP server in PolicyLayer and add a rule for interop_resolve: 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 Dual Registry. Nothing to install.

What risk level is interop_resolve? +

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

Can I rate-limit interop_resolve? +

Yes. Add a rate_limit block to the interop_resolve 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 interop_resolve completely? +

Set action: deny in the PolicyLayer policy for interop_resolve. 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 interop_resolve? +

interop_resolve is provided by the Dual Registry MCP server (https://www.dualregistry.dev/api/protocol). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
