It performs a search operation to find existing contacts, which is a read-only action with no capability to create, modify, delete, or execute operations. The blast radius of misuse is minimal—an attacker could enumerate contacts but cannot alter data or trigger external actions.

From the tool's definition Tool name 'planfix_search_contact' and description explicitly states it 'Search[es] for a contact' with no mention of modification, deletion, or execution capabilities. Accepts only query parameters (name, phone, email, telegram) for retrieval.

POLICY

How to control planfix_search_contact

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "planfix_search_contact": {}
  }
}

planfix_search_contact is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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