AI agents use patchv2objectsrecordsbyrecordid to create or update resources in Attio — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Attio environment.
The tool updates/modifies records in the Attio system (people, companies, etc.) which is a reversible Write operation. Severity is medium because modifying records could affect business data integrity and downstream processes, but the operation is reversible (unlike Destructive) and doesn't involve money (Financial) or code execution (Execute). The blast radius is limited to the specific record being patched.

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 patchv2objectsrecordsbyrecordid:
{
"version": "1",
"default": "deny",
"tools": {
"patchv2objectsrecordsbyrecordid": {
"limits": [
{
"counter": "patchv2objectsrecordsbyrecordid_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}patchv2objectsrecordsbyrecordid 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.
