AI agents call getv2objectsrecordsattributesvalues to retrieve information from Attio without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical and current attribute values from a record without creating, modifying, or deleting any data. It has read-only semantics and no side effects. Severity is low as attribute value queries pose minimal risk even if misused by an AI agent.
From the tool's definition Tool name contains 'get' and description states 'Gets all values for a given attribute on a record.' This is a data retrieval operation with no modification capability.

PolicyLayer is an MCP gateway — it sits between your AI agents and Attio, and nothing reaches the server without passing your rules. This is the rule we recommend for getv2objectsrecordsattributesvalues:
{
"version": "1",
"default": "deny",
"tools": {
"getv2objectsrecordsattributesvalues": {}
}
} getv2objectsrecordsattributesvalues is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Start from Attio, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
