Function list 

pub fn list(engine: &Engine) -> Result<Vec<CatalogEntry>, McpError>

Fetch every catalog row in name-sorted order. Returns an empty Vec if the catalog table doesn’t exist (callers shouldn’t need to pre-check).

Errors

• Propagates any error from table_present (connection failure during the existence probe).
• Propagates any error from Engine::execute_query_to_json.
• Propagates ErrorCode::SchemaMismatch from row_to_entry if a persisted row cannot be decoded into a CatalogEntry.
