AI agents call get_description_by_aid 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 appears to retrieve or query biomedical data (likely descriptions indexed by AID/accession identifier) from one of the 600+ integrated databases. Read operations on informational biomedical databases pose minimal risk—no data is modified, deleted, or executed. Lower confidence (0.7) due to missing description, but category assignment is robust based on naming pattern and server context.
From the tool's definition Tool name 'get_description_by_aid' indicates retrieval of descriptions by identifier (AID); sibling tools on this server (clinvar_query_*, depmap_get_*) are read-only data retrieval functions.

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_description_by_aid:
{
"version": "1",
"default": "deny",
"tools": {
"get_description_by_aid": {}
}
}get_description_by_aid is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_description_by_aid. 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_description_by_aid: 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_description_by_aid 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_description_by_aid 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_description_by_aid. 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_description_by_aid 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.
