Server has 7 tools with basic schemas and descriptions, but significant quality gaps. All tools have descriptions (10-60 chars, mostly short), and input schemas are present with Zod validation. However, descriptions are generic and lack actionable context for LLM selection. Parameter descriptions are minimal (e.g., 'Monad testnet address to check balance for' lacks format/validation hints). No output schemas documented. Error handling returns plain text without recovery guidance. Two IRREVERSIBLE tools (send-mon-transaction, deploy-mon-contract) lack confirmation/dry-run patterns. No tool annotations (readOnlyHint, destructiveHint). Tool names are verb-prefixed but lack clarity on resource type (e.g., 'send-mon-transaction' vs 'send-transaction', 'mon' is redundant given server context).

• Convert all tool responses from plain text to structured JSON. E.g., get-latest-block should return {"blockNumber": 12345, "hash": "0x...", "timestamp": 1234567890, "transactionCount": 42, "gasUsed": "1000000", "gasLimit": "2000000"} instead of concatenated strings.
• Add confirmation/dry-run pattern to send-mon-transaction and deploy-mon-contract. Implement a 'dry_run' boolean parameter or separate 'preview-transaction' tool that returns estimated gas/fees without executing.
• Enhance parameter descriptions with format constraints. E.g., 'Recipient address (0x-prefixed 40-char hex string, e.g. 0x1234...abcd)' instead of just 'Recipient address'.
• Implement error categorization and recovery guidance. Return {"error": "...", "category": "retryable|user_fixable|fatal", "suggestion": "Try calling search_blocks() with a different range"} instead of plain error text.
• Add tool annotations to schema. Mark send-mon-transaction and deploy-mon-contract with destructiveHint=true; mark read-only tools with readOnlyHint=true. This enables clients to apply safety policies.
