What summarize_run does on Nonmem

AI agents call summarize_run to retrieve information from Nonmem without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why summarize_run needs a policy

This tool reads and aggregates existing NONMEM run outputs (control stream, .ext, and .lst files) to produce a summary. It retrieves and combines data without modifying, executing, or deleting anything.

How to control summarize_run

PolicyLayer is an MCP gateway — it sits between your AI agents and Nonmem, and nothing reaches the server without passing your rules. This is the rule we recommend for summarize_run:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "summarize_run": {}
  }
}

summarize_run is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Nonmem — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
