Remove all sample associations and cleanup for a run (re-demux scenario).
AI agents call clear_samples_for_run to permanently remove resources in NGS360 MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly removes sample associations from a sequencing run, deleting relational data with no undo mechanism. In a bioinformatics pipeline, clearing samples from a completed run destroys metadata and associations that are foundational to data tracking and provenance.
From the tool's definition Tool name 'clear_samples_for_run' combined with description 'Remove all sample associations and cleanup for a run' indicates irreversible deletion of sample associations.
Attacks that exploit this kind of access
Remove all sample associations and cleanup for a run (re-demux scenario). It is categorised as a Destructive tool in the NGS360 MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the NGS360 MCP Server MCP server in PolicyLayer and add a rule for clear_samples_for_run: 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 NGS360 MCP Server. Nothing to install.
clear_samples_for_run 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 clear_samples_for_run 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 clear_samples_for_run. 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.
clear_samples_for_run is provided by the NGS360 MCP Server MCP server (ngs360/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
clear_samples_for_run is one line of NGS360 MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
