Extract genes in a cytogenetic band region (e.g., 'chr10q21').
AI agents call ensembl_get_genes_by_band 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 genomic data (genes within a specified cytogenetic band) from the Ensembl database. It performs a read-only query against a biomedical reference database. There are no side effects, data modifications, code execution, destructive operations, or financial implications.
From the tool's definition Tool name 'ensembl_get_genes_by_band' and description 'Extract genes in a cytogenetic band region' indicate a query/retrieval operation. The verb 'Extract' and 'get' denote data retrieval with no modification or execution of external operations.
Documented attack patterns abuse exactly the kind of access ensembl_get_genes_by_band 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 ensembl_get_genes_by_band:
{
"version": "1",
"default": "deny",
"tools": {
"ensembl_get_genes_by_band": {}
}
}ensembl_get_genes_by_band 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.
Extract genes in a cytogenetic band region (e.g., 'chr10q21'). 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 ensembl_get_genes_by_band: 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.
ensembl_get_genes_by_band 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 ensembl_get_genes_by_band 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 ensembl_get_genes_by_band. 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.
ensembl_get_genes_by_band 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.
