What post_vep_region does on OrigeneMCP
AI agents call post_vep_region to retrieve information from OrigeneMCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why post_vep_region is rated Low
The tool fetches variant effect predictions for genomic regions. Despite using 'post' in its name (likely referring to an HTTP POST used for sending region parameters), the operation is a data retrieval/query with no write, execute, or destructive side effects. Severity is low as it only reads bioinformatic annotation data.
From the tool's definition 'Get variant effect predictions by multiple regions' — retrieves/queries prediction data with no stated side effects
Attacks that exploit this kind of access
The rule that runs post_vep_region safely
PolicyLayer is an MCP gateway: it sits between your AI agents and OrigeneMCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For post_vep_region, this is the rule to start with:
post_vep_region is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect OrigeneMCP, apply this rule, and every post_vep_region call is checked against it from then on.
Questions about post_vep_region
Get variant effect predictions by multiple regions. 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 post_vep_region: 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.
post_vep_region 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 post_vep_region 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 post_vep_region. 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.
post_vep_region 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.
