Implementation Reference
- The handler function implementing the list_kv_keys tool. It constructs API parameters from input args and calls _make_request to fetch keys from Cloudflare Workers KV namespace.
async def _list_kv_keys(self, args: dict) -> Any: """List KV keys.""" account_id = args.get("account_id") or self.account_id if not account_id: raise ValueError("Account ID is required. Provide it in args or config.") params = {} if args.get("prefix"): params["prefix"] = args["prefix"] if args.get("limit"): params["limit"] = args["limit"] if args.get("cursor"): params["cursor"] = args["cursor"] return await self._make_request( f"/accounts/{account_id}/storage/kv/namespaces/{args['namespace_id']}/keys", params=params, ) - Input schema for list_kv_keys tool defining parameters: account_id (optional), namespace_id (required), prefix, limit, cursor.
