THE RISK

Why pipeline_summary needs a policy

This tool retrieves and displays aggregate information about a hiring pipeline's stages for a specific job. It has no side effects—it does not create, modify, delete, or execute any changes to the ATS data. It is a straightforward read operation analogous to a search or fetch operation.

From the tool's definition Tool name 'pipeline_summary' and description 'Get a stage-by-stage summary of a job' indicate a retrieval operation with no modification or deletion of data. The verb 'Get' and 'summary' confirm this is a query-only action.

POLICY

How to control pipeline_summary

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 pipeline_summary:

policy.json

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

pipeline_summary 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.
