WHAT IT DOES

What generate_kame_swap_calldata does on SEI MCP Server V2

AI agents use generate_kame_swap_calldata to create or update resources in SEI MCP Server V2 — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your SEI MCP Server V2 environment.

WHY IT NEEDS A POLICY

Why generate_kame_swap_calldata needs a policy

This tool generates swap calldata, which is a transaction preparation step. While the tool itself does not execute the swap (hence not Execute category), it creates transaction data that will modify blockchain state (token balances) when the generated calldata is subsequently submitted. This is a Write operation—reversible through counter-transactions.

From the tool's definition Tool name contains 'swap' and description states it 'Generates the transaction calldata' - indicating creation of transaction data that modifies state when executed.
