List items in the recycle bin.
AI agents call list_trash to retrieve information from Scifinder Route without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool only retrieves and displays information about deleted items in a recycle bin. It performs no side effects, modifications, or destructive actions. It is a straightforward Read operation analogous to listing or viewing data. While the server context involves synthesis routes and literature data, this particular tool is purely informational.
From the tool's definition Tool name is 'list_trash' and description states it 'List items in the recycle bin.' This is a query/retrieval operation with no modifications.
Attacks that exploit this kind of access
List items in the recycle bin. It is categorised as a Read tool in the Scifinder Route MCP Server, which means it retrieves data without modifying state.
Register the Scifinder Route MCP server in PolicyLayer and add a rule for list_trash: 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 Scifinder Route. Nothing to install.
list_trash 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_trash 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_trash. 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_trash is provided by the Scifinder Route MCP server (kettly1260/scifinder-route-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
