Get all supported genome assemblies from UCSC Genome Browser.
AI agents call list_genomes to retrieve information from OrigeneMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists publicly available genome assembly metadata from UCSC, which is a standard reference database. There are no side effects, no data modification, no execution of arbitrary code, and no financial implications. It is a read-only query operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name is 'list_genomes' and description states 'Get all supported genome assemblies from UCSC Genome Browser' — a straightforward data retrieval operation with no modification, deletion, or code execution capability.
Documented attack patterns abuse exactly the kind of access list_genomes gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and OrigeneMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for list_genomes:
{
"version": "1",
"default": "deny",
"tools": {
"list_genomes": {}
}
}list_genomes is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get all supported genome assemblies from UCSC Genome Browser. It is categorised as a Read tool in the OrigeneMCP MCP Server, which means it retrieves data without modifying state.
Register the Origene MCP server in PolicyLayer and add a rule for list_genomes: 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 OrigeneMCP. Nothing to install.
list_genomes 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_genomes 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_genomes. 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_genomes is provided by the Origene MCP server (gentel-lab/origenemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from OrigeneMCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
