This MCP server exhibits significant quality gaps across naming, descriptions, parameter documentation, and error handling. While 16 tools are declared, the source code provides limited visibility into actual implementation details, schemas, and error handling. Tool descriptions are present but often generic (10-50 chars), parameter schemas are minimally documented, and no evidence of structured error recovery guidance. The server appears to be a hybrid tool management + Solana blockchain interaction system, but tools like 'register' and 'execute_capability' rely on opaque 'object' type parameters without field-level schema definition. No toolAnnotations (readOnlyHint/destructiveHint/idempotentHint) are evident despite the risk classifications provided. High-risk operations (transfer_sol, deploy_contract, delete_tool) lack explicit confirmation/dry-run patterns.

• Expand 'manifest' and 'implementation' schemas in register(): define required fields (name, description, input_schema, output_schema), types, and validation rules. Use a JSON Schema definition, not bare 'object'.
• Document output schema for every tool. For list(): return { tools: [{ id, name, description, category, tags, risk_level }], total_count, next_cursor }. For transfer_sol(): return { transaction_id, status, timestamp, confirmations }.
• Add 'readOnlyHint': true to tools that only query state (get_*, list, describe). Add 'destructiveHint': true to tools that delete or transfer. Add 'idempotentHint': true to tools that are safe to retry.
• Enhance parameter descriptions with format, range, and enum constraints. Example: 'amount (in SOL, 0.001 - 1000000, must include decimal point, e.g. 1.5)'.
• Add pagination to list(): include optional 'limit' (default 20, max 100) and 'offset' (default 0) parameters. Return total_count so the agent knows how many results exist.
• Add error recovery hints to descriptions. Example for transfer_sol: 'On failure, returns error_code (insufficient_balance | invalid_address | network_error) and recovery hint (Verify address format | Check account balance | Retry in 30s).'
• Implement confirmation pattern for destructive operations: add optional 'dry_run': true parameter to delete_tool, transfer_sol, deploy_contract. When true, return a preview without committing. LLM can review and call again with dry_run=false.
• Define valid enum values for 'category' and 'tag' filters in list(), or document the discovery process (e.g. 'Call get_tool(tool_id) for available categories').
