AI agents call get_xref_source_ids 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.
Based on naming convention and server context as a biomedical information retrieval platform, this tool appears to fetch or query cross-reference identifiers from databases. No write, delete, code execution, or financial operations are indicated. Confidence is moderate (0.7) rather than high because the description is empty, leaving some uncertainty about actual implementation details.
From the tool's definition Tool name 'get_xref_source_ids' indicates retrieval of cross-reference source identifiers. The 'get_' prefix and 'xref' (cross-reference) terminology are characteristic of data retrieval operations.
Documented attack patterns abuse exactly the kind of access get_xref_source_ids 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_xref_source_ids:
{
"version": "1",
"default": "deny",
"tools": {
"get_xref_source_ids": {}
}
}get_xref_source_ids is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_xref_source_ids. 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_xref_source_ids: 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_xref_source_ids 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_xref_source_ids 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_xref_source_ids. 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_xref_source_ids 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.
