AI agents call check_virus_accessions 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 validates virus accession identifiers against a database, a read-only operation that retrieves or confirms information. No creation, modification, deletion, code execution, or financial impact is implied. The blast radius of misuse is minimal—incorrect validation queries cannot compromise system integrity or data. Classified as Read with low severity.
From the tool's definition Tool name 'check_virus_accessions' with description 'Check virus accessions validity' indicates a validation/lookup operation on virus accession identifiers.

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 check_virus_accessions:
{
"version": "1",
"default": "deny",
"tools": {
"check_virus_accessions": {}
}
}check_virus_accessions 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.
Check virus accessions validity. 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 check_virus_accessions: 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.
check_virus_accessions 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 check_virus_accessions 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 check_virus_accessions. 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.
check_virus_accessions 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.
