# get_erc20_balance Get the ERC20 token balance of an EVM address Agent View of the PolicyLayer registry record for `get_erc20_balance`. HTML page: https://policylayer.com/tools/testinguser1111111-sei-mcp-server/get-erc20-balance ## Facts - Tool: `get_erc20_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_erc20_balance", "arguments": {} } } ``` ## Why get_erc20_balance is rated Low This tool performs a read-only query to fetch the balance of an ERC20 token at a specified address. It has no side effects, does not modify state, and does not execute arbitrary code or trigger financial transactions. The operation is purely informational and consistent with the 'Read' category definition. From the tool's own definition: "Tool name 'get_erc20_balance' and description 'Get the ERC20 token balance of an EVM address' indicate a query operation that retrieves data without modification." ## Use case AI agents call get_erc20_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_erc20_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.
