Why delete_all_stopwords needs a policy

This tool permanently removes all custom stopwords from a search index. While it only affects custom stopwords (not the default language dictionary), the bulk deletion of all custom configuration is irreversible, qualifying it as Destructive. Severity is medium because it affects index configuration/behavior rather than primary data, but misuse could silently degrade search quality across the entire index.

From the tool's definition "Delete all custom stopwords from an index" — the word 'delete' and 'all' indicate irreversible bulk removal of data

POLICY

How to control delete_all_stopwords

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

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_all_stopwords"
  ]
}

delete_all_stopwords disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Searchcraft 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.
