THE RISK

Medium Risk

Why generate_agenda needs a policy

This tool creates new content (an agenda slide) and modifies the presentation structure by inserting it at a specific location. This is a reversible modification operation consistent with Write category. The severity is medium because while the action modifies the presentation, it is automatic, deterministic, and reversible—an agent could regenerate or delete the agenda slide if needed.

From the tool's definition The tool performs auto-generation and insertion of a slide (agenda), which modifies the presentation structure. The description states it will 'insert it before the first section,' indicating a create/modify operation that changes the presentation.

POLICY

How to control generate_agenda

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "generate_agenda": {
      "limits": [
        {
          "counter": "generate_agenda_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

generate_agenda 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.

Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Auto-generate an agenda slide from section slides (detected by CSS class) and insert it before the first section. It is categorised as a Write tool in the Marp MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on generate_agenda? +

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

What risk level is generate_agenda? +

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

Can I rate-limit generate_agenda? +

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

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

generate_agenda is provided by the Marp MCP Server MCP server (masaki39/marp-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Marp MCP Server tool call.
