Scored across 12 tools
Most tools have distinct purposes, but l402-discover and l402-fetch-preview overlap significantly: both probe a URL to return pricing without payment. l402-balance and l402-credentials also both expose cached credit balances, though at different scopes.
All tools share a consistent l402- prefix and snake_case style, which makes the set feel cohesive. However, not all follow the same verb_noun pattern: l402-balance, l402-config, and l402-credentials are noun-style names, while most others are verb-led.
Twelve tools is well-scoped for a payment-focused MCP server that needs to cover discovery, preview, fetching, paying, reconciliation, credentials, balance, and credit management. Each tool earns its place in the workflow.
The core L402 lifecycle is well covered: discover, preview, fetch, pay, store tokens, reconcile unknowns, buy credits, and redeem ecash. Minor gaps exist such as no explicit credential deletion or configuration update, but agents can complete the main payment flows without dead ends.
