This MCP server demonstrates solid definition quality with consistent naming patterns, comprehensive parameter schemas, and clear descriptions across all 15 tools. All tools follow the verb_noun naming convention (get_tvl, get-volume, etc.) and have non-empty descriptions. Input schemas are well-structured using Zod validation with type constraints and enums for constrained parameters. However, there are notable gaps: no output schemas are documented (critical for LLM reasoning about downstream tool composition), error handling is generic without recovery guidance, and several parameters lack inline format constraints. The server lacks tool annotations (readOnlyHint, idempotentHint) despite all tools being read-only operations. Description lengths average ~100 chars (within the 10-1024 range), meeting the baseline expectation. Parameter descriptions are present and descriptive (baseline 72 chars avg), though some could be more specific about format/constraints. No security issues detected (no secrets exposed as parameters). Tool composition is solid, each tool has a single responsibility, and output fields (wallet addresses, chain IDs) are named consistently with input parameters, supporting tool chaining.

• Document output schemas for all 15 tools. Include example response objects with field names, types, and descriptions. This is critical for LLM reasoning about downstream tool selection.
• Replace generic error handling with structured recovery guidance. Example: 'Invalid wallet address format. Expected 0x... Ethereum address. Did you mean to call get-smart-wallet-by-eoa first to discover wallet addresses?'
• Add tool annotations to all read-only tools. Modify tool registration to include {readOnlyHint: true} in each tool's metadata. This enables LLMs to confidently retry operations without side-effect concern.
• Enhance get-tvl and get-volume descriptions with context. Example: 'Get aggregate total value locked (TVL) across all Zyfai smart wallets across all supported chains (Base, Arbitrum, Plasma) and strategies. Returns current TVL snapshot. Call this first to understand platform scale before analyzing individual wallets.'
• Formalize pagination for list-like tools. Document that limit defaults to 20, max 100. Include total_count and next_cursor (if applicable) in response schemas. Add explicit: 'For large result sets, use limit=50 and pagination. Responses are capped at 100 items per page.'
• Standardize date parameter descriptions. Use consistent phrasing: 'ISO 8601 date (YYYY-MM-DD format, e.g. 2024-01-15)' for startDate/endDate. Use enum constraints in schema: days: z.enum(['7D', '14D', '30D']) with matching description.
• Add parameter interdependency notes. For get-daily-earnings, clarify: 'If both startDate and endDate are omitted, returns all available history. If only startDate is provided, returns data from startDate to present.'

• Relies on Stateful initialize / Mcp-Session-Id (removed; protocol is stateless) - make each request self-contained
