THE RISK

Medium Risk

Why generate_campaign needs a policy

This tool creates new data (prospecting messages/campaign) in a reversible manner. It does not execute external code or trigger external operations whose effects depend on arguments in an unpredictable way—it generates structured content. While 'generate' could suggest code execution, the context shows this is prospecting message generation for marketing campaigns, which is a Write operation (creating campaign data).

From the tool's definition Tool description states 'Generate prospecting messages for contacts WITHOUT existing messages as a campaign', indicating creation of new campaign message records.

POLICY

How to control generate_campaign

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

policy.json

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

generate_campaign 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 Prospectio MCP API — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Questions about generate_campaign

What does the generate_campaign tool do? +

How do I enforce a policy on generate_campaign? +

Register the Prospectio MCP API MCP server in PolicyLayer and add a rule for generate_campaign: 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 Prospectio MCP API. Nothing to install.

What risk level is generate_campaign? +

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

Can I rate-limit generate_campaign? +

Yes. Add a rate_limit block to the generate_campaign 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_campaign completely? +

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

generate_campaign is provided by the Prospectio MCP API MCP server (prospectio-ai/prospectio-api-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Prospectio MCP API tool call.

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