AI agents call Account to retrieve information from Patchwork Os without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears designed to reference or retrieve account objects by API name, which is a read operation with no mention of modification, deletion, or execution capabilities. Lower confidence due to incomplete/truncated description that leaves some ambiguity about actual functionality.
From the tool's definition Tool name 'Account' with description indicating 'sObject API name' suggests querying or retrieving account data from a Salesforce-like system. The incomplete description ('e.g.') and lack of detail about mutation capabilities suggest read-only access.
Documented attack patterns abuse exactly the kind of access Account gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Patchwork Os, and nothing reaches the server without passing your rules. This is the rule we recommend for Account:
{
"version": "1",
"default": "deny",
"tools": {
"Account": {}
}
}Account is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Patchwork Os MCP server in PolicyLayer and add a rule for Account: 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 Patchwork Os. Nothing to install.
Account is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the Account 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 Account. 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.
Account is provided by the Patchwork Os MCP server (oolab-labs/patchwork-os). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Patchwork Os, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
