delete_sample
AI agents call delete_sample to permanently remove resources in RSpace MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool performs deletion, which is irreversible and cannot be undone. In a research data management system like RSpace, deleting samples destroys data permanently. This is the most severe category (Destructive > Execute > Write > Read). Despite the empty description, the tool name itself is sufficiently explicit.
From the tool's definition Tool name is 'delete_sample' with empty description. The verb 'delete' combined with the RSpace context (a research data management system) indicates irreversible removal of sample data.
Attacks that exploit this kind of access
delete_sample. It is categorised as a Destructive tool in the RSpace MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the RSpace MCP Server MCP server in PolicyLayer and add a rule for delete_sample: 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 RSpace MCP Server. Nothing to install.
delete_sample is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_sample 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 delete_sample. 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.
delete_sample is provided by the RSpace MCP Server MCP server (rspace-os/rspace-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
