WHAT IT DOES

What identity_resolve does on Munin

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

RISK

Why identity_resolve is rated Medium

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

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs identity_resolve safely

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

identity_resolve Rate-limited

identity_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 Munin, apply this rule, and every identity_resolve call is checked against it from then on.

FAQ

Questions about identity_resolve

What does the identity_resolve tool do? +

Find the end-user identity that an email address, phone number, external id, or analytics visitor id belongs to. An end user is the durable per-person record created the first time someone reaches the org on any channel — inbound email, chat widget, or an analytics identify call — so it exists for people who have no CRM contact yet. Returns. It is categorised as a Write tool in the Munin 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_resolve? +

Register the Munin MCP server in PolicyLayer and add a rule for identity_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 Munin. Nothing to install.

What risk level is identity_resolve? +

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

Can I rate-limit identity_resolve? +

Yes. Add a rate_limit block to the identity_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 identity_resolve completely? +

Set action: deny in the PolicyLayer policy for identity_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 identity_resolve? +

identity_resolve is provided by the Munin MCP server (https://mcp.getmunin.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
