Server has 4 tools with clear verb-noun naming (list_*, execute_*, describe_*). All tools have descriptions and input schemas with types. However, descriptions lack depth on WHEN to use each tool and dependencies between them. Parameter descriptions are minimal (e.g., 'Name of the database connection' repeated 3 times). Output schemas are documented via Pydantic models but not explicitly described in tool docstrings. Error handling returns structured ErrorResponse but lacks recovery guidance. Security concern: execute_query accepts raw SQL with only a user-confirmation pattern for large updates, no SQL injection prevention visible in tool definition.

• Add explicit output schema documentation to each tool docstring. Example: 'Returns: {success: true, data: {columns: [string], rows: [[any]], row_count: int}}'
• Enhance parameter descriptions with context and dependencies. Example: 'connection_name: Name of the database connection (see list_connections to discover available connections)'
• Implement parameterized query support or add SQL validation/sanitization guidance in execute_query description and error messages.
• Enrich error responses with available alternatives. When connection_name is invalid, return list of valid connection names. When table_name is invalid, return list of available tables.
• Migrate from ctx.elicit() to MCP 2026-07-28 Multi Round-Trip Requests pattern for update confirmation (return result with 'input_required' action instead of awaiting elicit).

Inferred effective spec: 2026-07-28+.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
