create_regional_plot · Gwas MCP: Risk & Policy

WHAT IT DOES

What create_regional_plot does on Gwas

AI agents use create_regional_plot to create or update resources in Gwas — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Gwas environment.

WHY IT NEEDS A POLICY

Why create_regional_plot needs a policy

This tool generates a visualization artifact (regional plot) that modifies the user's data/output environment by creating new plot files or data representations. While not destructive or executable in the dangerous sense, it is generative—it writes new data (plot files) to storage.

From the tool's definition Tool creates and generates a regional association plot (LocusZoom-style visualization), which produces new graphical data output that is stored/saved as a result of the operation.

create_regional_plot Rate-limited

create_regional_plot stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

What does the create_regional_plot tool do? +

Create a regional association plot (LocusZoom-style) for a specific genomic region around a lead SNP. It is categorised as a Write tool in the Gwas MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_regional_plot? +

Register the Gwas MCP server in PolicyLayer and add a rule for create_regional_plot: 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 Gwas. Nothing to install.

What risk level is create_regional_plot? +

create_regional_plot is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_regional_plot? +

Yes. Add a rate_limit block to the create_regional_plot 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.

How do I block create_regional_plot completely? +

Set action: deny in the PolicyLayer policy for create_regional_plot. 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.

What MCP server provides create_regional_plot? +

create_regional_plot is provided by the Gwas MCP server (muslus/gwas-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
