WHAT IT DOES

What list_chromosomes does on OrigeneMCP

AI agents call list_chromosomes to retrieve information from OrigeneMCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_chromosomes is rated Low

This tool appears to retrieve chromosome information from a biomedical database without modifying, deleting, or executing code. The 'list_' prefix strongly indicates a read-only query operation. The context of the OrigeneMCP server—focused on information retrieval across genes, molecules, and diseases—supports this classification.

From the tool's definition Tool name 'list_chromosomes' indicates a retrieval operation that lists chromosomal data. The name follows the 'list_*' pattern typical of Read operations (list, get, fetch).

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_chromosomes safely

PolicyLayer is an MCP gateway: it sits between your AI agents and OrigeneMCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_chromosomes, this is the rule to start with:

list_chromosomes Allowed

list_chromosomes is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_chromosomes": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect OrigeneMCP, apply this rule, and every list_chromosomes call is checked against it from then on.
