AI agents call get_ga4gh_referencesets 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.
The 'get_' prefix strongly suggests a read-only retrieval operation for accessing GA4GH reference sets, which are static reference data used in genomic analysis. This is consistent with sibling tools that query and retrieve biomedical data (clinvar_query_*, depmap_get_*). No indication of write, delete, execute, or financial operations.
From the tool's definition Tool name 'get_ga4gh_referencesets' uses 'get' verb indicating data retrieval. GA4GH (Global Alliance for Genomics and Health) reference sets are standard biomedical reference data structures used in genomic research.
Documented attack patterns abuse exactly the kind of access get_ga4gh_referencesets 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 get_ga4gh_referencesets:
{
"version": "1",
"default": "deny",
"tools": {
"get_ga4gh_referencesets": {}
}
}get_ga4gh_referencesets 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_ga4gh_referencesets. 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 get_ga4gh_referencesets: 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.
get_ga4gh_referencesets 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 get_ga4gh_referencesets 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 get_ga4gh_referencesets. 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.
get_ga4gh_referencesets 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.
