create_multihop_path · SEI MCP Server V2 MCP: Risk & Policy

WHAT IT DOES

What create_multihop_path does on SEI MCP Server V2

AI agents use create_multihop_path 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 create_multihop_path needs a policy

This tool creates/encodes a swap path used in multi-hop DeFi swaps. It is a preparatory Write action that constructs data (an encoded path) rather than executing a swap directly. However, the encoded path is likely consumed by swap execution tools, so misuse could indirectly facilitate unintended trades. No direct financial transaction or irreversible action is performed by this tool alone.

From the tool's definition 'Create encoded path for multi-hop swaps' - creates an encoded routing path for multi-hop token swap transactions

create_multihop_path Rate-limited

create_multihop_path stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
