THE RISK

Medium Risk

Why bulk_create_candidates needs a policy

This tool creates new candidate records in Ashby's ATS, which is a write operation that modifies data reversibly. While bulk operations affect multiple records, candidate creation can be undone through deletion. Severity is medium because creating invalid or spam candidates could pollute the recruiting database and cause operational friction, but does not result in irreversible loss or financial impact per se.

From the tool's definition Tool name contains 'create' and description states 'Create multiple candidates in a single operation', indicating it creates/adds new records in bulk to the ATS system.

POLICY

How to control bulk_create_candidates

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

policy.json

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

bulk_create_candidates 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.
