peage-mcp exhibits significant definition quality gaps. Tool names lack action verbs (peage_solvency, peage_status, peage_feedback use domain prefix instead of verb_noun pattern). Descriptions are present but minimal (10-50 chars), below the 50-200 char LLM-optimized baseline. Only 3 tools (peage_feedback, paid_request, peage_history) have documented parameters. No output schemas are documented. Error handling is minimal, test.sh shows basic isError flags but no recovery guidance. Tool composition is reasonable (single concerns), but parameter descriptions are sparse or absent.

• Rename all tools to verb_noun pattern: peage_solvency → check_solvency, peage_status → get_status, peage_feedback → submit_feedback, peage_services → list_services, peage_setup → initialize_wallet, peage_receipt → retrieve_receipt, peage_balance → check_balance, peage_history → list_transactions.
• Expand descriptions to 50-200 chars with WHAT, WHEN, and prerequisites. Example: 'Check if the account is solvent on the Peage rail. Call this before making paid requests. Requires wallet setup.' (current: 42 chars).
• Add input schemas to all 6 empty-schema tools. Even read-only tools like check_solvency and list_services should declare {} explicitly with a comment, or add optional parameters (e.g., list_services with optional limit/offset for pagination).
• Document output schemas for all tools. Publish the structure of 'content', 'isError', 'text' fields and any nested JSON. Include example responses in tool descriptions or a separate schema document.
• Enhance error messages with recovery guidance. When wallet is not set up, return: 'Wallet not configured. Call initialize_wallet() first, then retry.' Instead of bare error flags.
