List available destinations from the Unstructured API.
AI agents call list_destinations 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.
This tool retrieves or enumerates available destination connectors (Weaviate, Pinecone, MongoDB, etc.) without modifying, deleting, or executing operations. It is purely informational. Low severity because listing destinations poses minimal risk—an AI agent cannot misuse this to cause harm or unintended side effects.
From the tool's definition Tool name 'list_destinations' and description 'List available destinations from the Unstructured API' indicate a query/retrieval operation with no side effects.
Attacks that exploit this kind of access
List available destinations from 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_destinations: 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_destinations 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_destinations 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_destinations. 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_destinations is provided by the Unstructured API MCP Server MCP server (liuchongchong1995/uns-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
