How to control resolve_player_id

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "resolve_player_id": {}
  }
}

resolve_player_id is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register Nba Stats — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
