AI agents call get_virus_by_taxon_genome 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 is a straightforward data retrieval operation that queries a biomedical database to fetch virus genome information filtered by taxonomic classification. It has no side effects, does not modify data, execute code, delete records, or involve financial transactions. It belongs in the Read category with low severity since misuse would only expose existing public or research database information.
From the tool's definition Tool name 'get_virus_by_taxon_genome' and description 'Get virus genome by taxon' indicate data retrieval functionality. The verb 'get' and the retrieval-focused description show this queries or fetches existing viral genome data without modification.
Documented attack patterns abuse exactly the kind of access get_virus_by_taxon_genome 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_virus_by_taxon_genome:
{
"version": "1",
"default": "deny",
"tools": {
"get_virus_by_taxon_genome": {}
}
}get_virus_by_taxon_genome 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 virus genome by taxon. 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_virus_by_taxon_genome: 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_virus_by_taxon_genome 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_virus_by_taxon_genome 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_virus_by_taxon_genome. 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_virus_by_taxon_genome 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.
