Import multiple leads into a campaign at once.
AI agents use smartlead_bulk_import_leads to create or update resources in Smartlead Simplified MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Smartlead Simplified MCP Server environment.
This tool creates or adds multiple lead records to a campaign, which is a reversible write operation. While it modifies campaign data, it doesn't delete or permanently destroy information, nor does it execute arbitrary code or trigger external side effects beyond the intended data import.
From the tool's definition Tool name contains 'import' and description states 'Import multiple leads into a campaign at once' — indicates data creation/addition operation. The 'bulk' aspect suggests high volume of records being added.
Documented attack patterns abuse exactly the kind of access smartlead_bulk_import_leads gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Smartlead Simplified MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for smartlead_bulk_import_leads:
{
"version": "1",
"default": "deny",
"tools": {
"smartlead_bulk_import_leads": {
"limits": [
{
"counter": "smartlead_bulk_import_leads_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}smartlead_bulk_import_leads 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.

Import multiple leads into a campaign at once. It is categorised as a Write tool in the Smartlead Simplified MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Smartlead Simplified MCP Server MCP server in PolicyLayer and add a rule for smartlead_bulk_import_leads: 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 Smartlead Simplified MCP Server. Nothing to install.
smartlead_bulk_import_leads is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the smartlead_bulk_import_leads 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.
Set action: deny in the PolicyLayer policy for smartlead_bulk_import_leads. 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.
smartlead_bulk_import_leads is provided by the Smartlead Simplified MCP Server MCP server (jonathan-politzki/smartlead-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Smartlead Simplified MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
