11 tools with complete input schemas and descriptions. Naming follows verb_noun pattern (list_, sql_, backups_, secrets_, connection_, status). Descriptions are concise (20-150 chars) and action-oriented. All parameters have type and description. However, output schemas are not documented in the visible code, only inferred from handler return types. Error handling is present (write-gate refusals tested) but recovery guidance is minimal. Tool composition is clean: each tool has one responsibility. No secrets exposed as parameters (password handling is server-side). Read-only hints and write-gate authorization patterns are well-implemented.

• Document output schemas explicitly in tool registration. For each tool, declare the return type with field names, types, and descriptions. Example: list_environments returns {environments: [{name: string, project: string, protected: boolean, profiles: [{name: string}]}]}.
• Add recovery guidance to error messages. Instead of 'authorize=true required', return 'Non-prod writes require authorize=true. Call this tool again with authorize=true, or use list_environments to see which environments are protected.'
• Add limit and offset parameters to list tools (sql_databases, sql_users, backups_list, secrets_list) with defaults (limit=50) and return a total_count field so agents can paginate large result sets.
• Sanitize the 'grep' parameter in logs tool. Validate it as a literal substring (no regex or shell metacharacters) or use a safe grep library. Document: 'grep is treated as a literal substring, not a regex.'
• For connection_string, never return the password in the response, even when include_password=true. Instead, return a flag (password_included: true) and have the agent retrieve the password via a separate secure channel or environment variable injection.
