# estimate_gas Estimate the gas cost for a transaction Agent View of the PolicyLayer registry record for `estimate_gas`. HTML page: https://policylayer.com/tools/testinguser1111111-sei-mcp-server/estimate-gas ## Facts - Tool: `estimate_gas` - 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": "estimate_gas", "arguments": {} } } ``` ## Why estimate_gas is rated Low This tool performs a read-only calculation to estimate gas fees before transaction execution. It queries blockchain parameters to return a cost estimate but does not create, modify, delete, or execute any actual transactions. The operation is informational with no side effects, matching the Read category definition of retrieves or queries data. From the tool's own definition: "Tool name 'estimate_gas' combined with description 'Estimate the gas cost for a transaction' indicates a query operation that retrieves cost estimation data without executing or modifying any blockchain state." ## Use case AI agents call estimate_gas 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": { "estimate_gas": {} } } ``` ## 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.
