Get features overlapping a translation (protein)
AI agents call overlap_translation 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 queries genomic data to retrieve information about features that overlap with a specific protein translation. It is a read-only operation that retrieves and returns data from the Ensembl database without creating, modifying, deleting, or executing any external operations.
From the tool's definition Tool name is 'overlap_translation' and description states 'Get features overlapping a translation (protein)' — a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
Get features overlapping a translation (protein). 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 overlap_translation: 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.
overlap_translation 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 overlap_translation 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 overlap_translation. 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.
overlap_translation 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.
