WHAT IT DOES

What over_representation_analysis does on miEAA3 MCP Server

AI agents invoke over_representation_analysis to trigger actions in miEAA3 MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why over_representation_analysis needs a policy

This tool executes a statistical analysis operation (over-representation analysis) against an external bioinformatics platform. While not destructive and not a direct code/shell execution, it triggers a complex external operation whose outcomes depend entirely on the arguments supplied (miRNA set, version, parameters).

From the tool's definition Tool description states 'Run miEAA over-representation analysis (ORA)' — the verb 'Run' indicates execution of an external bioinformatics analysis operation.

Verdict

over_representation_analysis Rate-limited

over_representation_analysis stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about over_representation_analysis

What does the over_representation_analysis tool do? +

Run miEAA over-representation analysis (ORA) for miRNA or precursor. It is categorised as a Execute tool in the miEAA3 MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on over_representation_analysis? +

Register the miEAA3 MCP Server MCP server in PolicyLayer and add a rule for over_representation_analysis: 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 miEAA3 MCP Server. Nothing to install.

What risk level is over_representation_analysis? +

over_representation_analysis is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit over_representation_analysis? +

Yes. Add a rate_limit block to the over_representation_analysis 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 over_representation_analysis completely? +

Set action: deny in the PolicyLayer policy for over_representation_analysis. 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 over_representation_analysis? +

over_representation_analysis is provided by the miEAA3 MCP Server MCP server (kkshrihari/mieaa3_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
