AI agents call get_virus_genome_download 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 virus genome sequences from an accession identifier without modifying, deleting, or executing arbitrary code. It is a straightforward data retrieval operation from a public biomedical database (similar to NCBI GenBank access patterns). The blast radius of misuse is limited to unauthorized access to genomic data, which has low immediate impact.
From the tool's definition Tool name is 'get_virus_genome_download' with description 'Download virus genome by accessions'. The verb 'Download' and 'get' indicate retrieval of pre-existing data from a biomedical database without modification or deletion.

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_genome_download:
{
"version": "1",
"default": "deny",
"tools": {
"get_virus_genome_download": {}
}
}get_virus_genome_download 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.
Download virus genome by accessions. 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_genome_download: 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_genome_download 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_genome_download 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_genome_download. 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_genome_download 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.
