Server has 6 tools with complete input schemas and basic descriptions. Naming follows verb_noun convention (get_, search_, latest_). However, descriptions are inconsistent in depth and lack actionable context for LLM selection. Parameter descriptions are minimal or absent (e.g., 'chain_id' lacks format guidance). No output schemas documented. Error handling is basic (404, 429, generic errors) with no recovery guidance. Missing parameter constraints (enums for chain values, limits for result counts). No tool annotations (readOnlyHint present via Risk field but not in MCP schema). Composition is sound, each tool has one responsibility. Overall: functional but below production baseline for agent-facing tools.

• Document output schemas for all 6 tools. Example for get_pair: {type: 'object', properties: {pair: {type: 'object', properties: {chainId: {type: 'string'}, pairAddress: {type: 'string'}, priceUsd: {type: 'string'}, liquidity: {type: 'object'}, volume24h: {type: 'object'}, txns: {type: 'object'}}}, schemaVersion: {type: 'string'}}}
• Convert 'chain' parameter to enum: {type: 'string', enum: ['ethereum', 'solana', 'bsc', 'polygon', 'arbitrum', 'base', 'avalanche', 'fantom', 'optimism', 'celo', 'gnosis', 'linea', 'scroll', 'zksync', 'zkfair', 'pulsechain', 'core', 'sei', 'blast', 'mode', 'mantle', 'manta', 'merlin', 'berachain', 'sonic', 'ink', 'abstract', 'movement', 'monad', 'story', 'worldchain', 'superseed', 'apechain', 'unichain', 'degen', 'mint', 'shape', 'fraxtal', 'bob', 'lorenzo', 'sonictest', 'taiko', 'immutable', 'arbitrumNova', 'arbitrumSepolia', 'baseSepolia', 'ethereumSepolia', 'polygonMumbai', 'polygonAmoy', 'solanaMainnet', 'solanaDevnet', 'solanaTestnet']}. Add description: 'Blockchain network identifier. Must be one of the supported chains listed.'
• Enhance error messages with recovery guidance. Example: if (res.status === 404) throw new Error('DEX Screener: pair not found. Try search_pairs() to find the correct pair address, or verify the chain and pair_address parameters.'); if (res.status === 429) throw new Error('DEX Screener: rate limit exceeded (HTTP 429). Wait 60 seconds before retrying. Consider batching requests.');
• Expand descriptions for latest_token_profiles and latest_boosted_tokens to 100-150 chars. Example: 'Fetch the newest token profiles created across all supported chains. Use this to discover recently launched tokens. Returns up to 50 profiles with name, symbol, chain, and profile metadata. Call this before search_pairs if you want trending tokens.'
