Estimate gas cost for a DragonSwap token swap
AI agents call estimate_swap_gas to retrieve information from SEI MCP Server V2 without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only calculation/estimation of gas costs. It does not execute a swap, transfer tokens, or modify blockchain state—it merely retrieves or computes an estimate for informational purposes. The word 'estimate' confirms this is a predictive query, not an action. Severity is low because misuse would only return incorrect estimates without causing financial or operational harm.
From the tool's definition Tool name 'estimate_swap_gas' and description 'Estimate gas cost for a DragonSwap token swap' indicate a query operation that retrieves estimated data without executing transactions or modifying state.
Attacks that exploit this kind of access
Estimate gas cost for a DragonSwap token swap. It is categorised as a Read tool in the SEI MCP Server V2 MCP Server, which means it retrieves data without modifying state.
Register the SEI MCP Server V2 MCP server in PolicyLayer and add a rule for estimate_swap_gas: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches SEI MCP Server V2. Nothing to install.
estimate_swap_gas is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the estimate_swap_gas rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for estimate_swap_gas. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
estimate_swap_gas is provided by the SEI MCP Server V2 MCP server (testinguser1111111/sei-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
