AI agents call get_xrefs_id 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 existing data (cross-references) indexed by an identifier, with no side effects or data modification. It is a standard lookup/query operation typical of read-only database access. The sibling tools (check_genome_accessions, clinvar_query_variant_significance, depmap_get_expression) are all read operations, consistent with this classification.
From the tool's definition Tool name 'get_xrefs_id' and description 'Get cross references by ID' indicate a retrieval operation. The verb 'Get' and the context of a biomedical database tool retrieving cross-reference data (links between identifiers across different databases) show no…
Documented attack patterns abuse exactly the kind of access get_xrefs_id 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_xrefs_id:
{
"version": "1",
"default": "deny",
"tools": {
"get_xrefs_id": {}
}
}get_xrefs_id is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get cross references by ID. 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_xrefs_id: 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_xrefs_id 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_xrefs_id 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_xrefs_id. 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_xrefs_id 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.
