AI agents call search-leads to retrieve information from Pipedrive MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The search function retrieves or queries lead records based on a search term. It does not create, modify, delete, or execute external operations. This is a straightforward read operation with minimal risk if misused by an AI agent, as it only returns matching lead data.
From the tool's definition Tool name is 'search-leads' and description states 'Search leads by term' — this is a query operation that retrieves data without modification or side effects.
Documented attack patterns abuse exactly the kind of access search-leads gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Pipedrive MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search-leads:
{
"version": "1",
"default": "deny",
"tools": {
"search-leads": {}
}
}search-leads is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search leads by term. It is categorised as a Read tool in the Pipedrive MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Pipedrive MCP Server MCP server in PolicyLayer and add a rule for search-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 Pipedrive MCP Server. Nothing to install.
search-leads is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the search-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 search-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.
search-leads is provided by the Pipedrive MCP Server MCP server (teapot-agency/mcp_pipedrive). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Pipedrive MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
