Get regulatory features in a genomic region
AI agents call get_regulatory_features to retrieve information from Ensembl MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves genomic regulatory feature data from the Ensembl database without creating, modifying, deleting, or executing any operations. It is a pure query/fetch operation with no side effects, placing it squarely in the Read category. The severity is low because misuse would only expose publicly available genomic data; there is no destructive, financial, or code-execution risk.
From the tool's definition Tool name 'get_regulatory_features' and description 'Get regulatory features in a genomic region' indicate a retrieval operation.
Attacks that exploit this kind of access
Get regulatory features in a genomic region. It is categorised as a Read tool in the Ensembl MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Ensembl MCP Server MCP server in PolicyLayer and add a rule for get_regulatory_features: 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 Ensembl MCP Server. Nothing to install.
get_regulatory_features 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_regulatory_features 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_regulatory_features. 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_regulatory_features is provided by the Ensembl MCP Server MCP server (munch-group/ensembl-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
