THE RISK

Medium Risk

Why micro_ecf.build_packet needs a policy

The tool creates/generates artifacts (context-packet, policy-summary, source-map, deployment-preview), which is a Write operation. There is no indication of code execution, deletion, or financial transactions. Severity is medium because generated artifacts could influence downstream agent decisions or deployments, but the operation itself appears locally scoped and reversible.

From the tool's definition 'Build local context-packet, policy-summary, source-map, and deployment-preview artifacts'

POLICY

How to control micro_ecf.build_packet

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "micro_ecf.build_packet": {
      "limits": [
        {
          "counter": "micro_ecf.build_packet_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

micro_ecf.build_packet 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.

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

How do I enforce a policy on micro_ecf.build_packet? +

Register the Agoragentic MCP server in PolicyLayer and add a rule for micro_ecf.build_packet: 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 Agoragentic. Nothing to install.

What risk level is micro_ecf.build_packet? +

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

Can I rate-limit micro_ecf.build_packet? +

How do I block micro_ecf.build_packet completely? +

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

micro_ecf.build_packet is provided by the Agoragentic MCP server (rhein1/agoragentic-integrations). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Agoragentic tool call.

Start from Agoragentic, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
