HTML page: https://policylayer.com/tools/testinguser1111111-sei-mcp-server/is-symphony-token-listed ## Facts - Tool: `is_symphony_token_listed` - 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": "is_symphony_token_listed", "arguments": {} } } ``` ## Why is_symphony_token_listed is rated Low This tool performs a lookup or verification check against the Symphony protocol to determine token listing status. It retrieves data (availability status) with no side effects, no code execution, no financial operations, and no data modification. It is a pure read operation typical of data queries on a blockchain. From the tool's own definition: "Tool name 'is_symphony_token_listed' and description 'Checks if a given token address is available for swaps' indicate a query operation that retrieves information without modifying state or executing external actions." ## Use case AI agents call is_symphony_token_listed 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": { "is_symphony_token_listed": {} } } ``` ## 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.
