Why candidate_list_notes needs a policy

It has no side effects and poses minimal security risk beyond potential information disclosure, which is typical of read operations in HR systems.

From the tool's definition Tool name 'candidate_list_notes' and description 'List all notes for a candidate. Returns note content, author, and date.' indicate a read-only query operation that retrieves existing data without modification.

POLICY

How to control candidate_list_notes

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

policy.json

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

candidate_list_notes 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 Ashby 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.
