# get_nft_balance Get the total number of NFTs owned by an address from a specific collection. Agent View of the PolicyLayer registry record for `get_nft_balance`. HTML page: https://policylayer.com/tools/testinguser1111111-sei-mcp-server/get-nft-balance ## Facts - Tool: `get_nft_balance` - Server: SEI MCP Server V2 (`testinguser1111111/sei-mcp-server`) — https://policylayer.com/tools/testinguser1111111-sei-mcp-server.md - Homepage: https://github.com/testinguser1111111/sei-mcp-server - Risk category: Read (Low risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Allowed ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "get_nft_balance", "arguments": {} } } ``` ## Why get_nft_balance is rated Low This tool queries blockchain state to retrieve balance information. It performs a read-only operation that retrieves data without modifying, deleting, or executing any state-changing actions. The operation is informational only and carries minimal risk even if an AI agent misuses it, as no assets, configurations, or data can be altered. From the tool's own definition: "Tool name 'get_nft_balance' and description 'Get the total number of NFTs owned by an address from a specific collection' indicate a pure data retrieval operation with no side effects." ## Use case AI agents call get_nft_balance to retrieve information from SEI MCP Server V2 without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere. ## Recommended policy (PolicyLayer) Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches SEI MCP Server V2: ```json { "version": "1", "default": "deny", "tools": { "get_nft_balance": {} } } ``` ## Other tools on SEI MCP Server V2 (186) - `cancel_debridge_order` — Destructive — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/cancel-debridge-order.md - `cancel_opensea_order` — Destructive — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/cancel-opensea-order.md - `citrex_cancel_open_orders_for_product` — Destructive — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/citrex-cancel-open-orders-for-product.md - `citrex_cancel_order` — Destructive — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/citrex-cancel-order.md - `citrex_cancel_orders` — Destructive — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/citrex-cancel-orders.md - `remove_liquidity` — Destructive — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/remove-liquidity.md - `citrex_cancel_and_replace_order` — Execute — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/citrex-cancel-and-replace-order.md - `deploy_erc20` — Execute — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/deploy-erc20.md - `deploy_erc721` — Execute — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/deploy-erc721.md - `execute_flash_loan` — Execute — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/execute-flash-loan.md - `execute_multihop_swap` — Execute — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/execute-multihop-swap.md - `execute_simple_flash_loan` — Execute — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/execute-simple-flash-loan.md - `execute_swap` — Execute — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/execute-swap.md - `write_contract` — Execute — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/write-contract.md - `borrow_yei_asset` — Financial — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/borrow-yei-asset.md - `buy_opensea_nft` — Financial — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/buy-opensea-nft.md - `citrex_deposit` — Financial — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/citrex-deposit.md - `citrex_place_orders` — Financial — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/citrex-place-orders.md - `citrex_withdraw` — Financial — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/citrex-withdraw.md - `create_and_execute_debridge_order` — Financial — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/create-and-execute-debridge-order.md - `create_debridge_order` — Financial — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/create-debridge-order.md - `create_opensea_collection_offer` — Financial — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/create-opensea-collection-offer.md - `create_opensea_offer` — Financial — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/create-opensea-offer.md - `delegate_credit_by_debt_token` — Financial — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/delegate-credit-by-debt-token.md - `fulfill_opensea_order` — Financial — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/fulfill-opensea-order.md - `repay_yei_asset` — Financial — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/repay-yei-asset.md - `swap_on_symphony` — Financial — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/swap-on-symphony.md - `swap_on_symphony_advanced` — Financial — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/swap-on-symphony-advanced.md - `transfer_erc20` — Financial — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/transfer-erc20.md - `transfer_sei` — Financial — https://policylayer.com/tools/testinguser1111111-sei-mcp-server/transfer-sei.md - …and 156 more: https://policylayer.com/tools/testinguser1111111-sei-mcp-server.md ## For agents This record is a snapshot.
