Scored across 3 tools
Each tool has a clearly distinct purpose: wallet management, chat with micropayments, and consumption record querying. There is no overlap or ambiguity between them; even the actions within token4u_wallet are well-separated.
All tool names follow the consistent pattern 'token4u_<noun>' using snake_case. This makes the toolset predictable and easy to navigate for agents.
With only 3 tools, the server is tightly scoped to its purpose of handling x402 micropayments via a local wallet. Each tool provides a distinct and necessary function, and none feel redundant or superfluous.
The set covers the full workflow: wallet creation/funding guidance, chat with micropayments, and transaction consumption queries. A minor gap is the lack of a direct balance-check tool, but the core functionality is complete for the stated purpose.
