Claude Code permissions

Allow the reads, ask before a change, deny the deletes. Paste into .claude/settings.json.

  "permissions": {
    "allow": [],
    "ask": [
      "mcp__defi-router__dex_liquidity_router",

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. It assumes the server is installed as defi-router. Review it before you use it.
