AI agents call list_jobs to retrieve information from Unstructured API MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'list' verb combined with the straightforward description establishes this as a data retrieval operation. It fetches job information without modifying, executing, or deleting anything. The low severity reflects minimal blast radius—an agent misusing this tool would only retrieve unwanted information, not cause operational damage or data loss.
From the tool's definition Tool name 'list_jobs' and description 'List jobs via the Unstructured API' indicate a query/retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_jobs gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Unstructured API MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_jobs:
{
"version": "1",
"default": "deny",
"tools": {
"list_jobs": {}
}
}list_jobs is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List jobs via the Unstructured API. It is categorised as a Read tool in the Unstructured API MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Unstructured API MCP Server MCP server in PolicyLayer and add a rule for list_jobs: 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 Unstructured API MCP Server. Nothing to install.
list_jobs 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 list_jobs 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 list_jobs. 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.
list_jobs is provided by the Unstructured API MCP Server MCP server (unstructured-io/uns-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
