Why prefill_job needs a policy

Scraping a job implies reading and retrieving data from a job posting page. However, given the server context mentions 'prefill applications using AI', this tool likely also involves writing prefill data into an application form. The description is minimal ('Scrape a job'), which reduces confidence.

From the tool's definition Tool description says 'Scrape a job', which implies fetching/retrieving job data from an external source

POLICY

How to control prefill_job

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

policy.json

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

prefill_job 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 Shortlist 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.
