AI agents use patchv2attributesoptionsbyoption 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.
This tool modifies existing data (a select option) in a reversible way — it updates an attribute option rather than deleting it or executing arbitrary code. It could affect data consistency if misused, hence medium severity, but it remains a Write operation.

Documented attack patterns abuse exactly the kind of access patchv2attributesoptionsbyoption gives an agent:
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 patchv2attributesoptionsbyoption:
{
"version": "1",
"default": "deny",
"tools": {
"patchv2attributesoptionsbyoption": {
"limits": [
{
"counter": "patchv2attributesoptionsbyoption_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}patchv2attributesoptionsbyoption 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.

Updates a select option on an attribute on either an object or a list. Required scopes: \. It is categorised as a Write tool in the Attio MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Attio MCP server in PolicyLayer and add a rule for patchv2attributesoptionsbyoption: 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 Attio. Nothing to install.
patchv2attributesoptionsbyoption is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the patchv2attributesoptionsbyoption 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.
Set action: deny in the PolicyLayer policy for patchv2attributesoptionsbyoption. 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.
patchv2attributesoptionsbyoption is provided by the Attio MCP server (itsbrex/attio-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Attio, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
