Implementation Reference
- MCP handler function that executes the list_ansible_collections tool: calls DB helper, applies filters, formats output as text content.async def handle_list_ansible_collections( db: Any, arguments: Dict[str, Any], operation_id: str ) -> list[types.TextContent | types.ImageContent | types.EmbeddedResource]: """Handle list_ansible_collections tool.""" try: logger.info("Listing Ansible collections", extra={"operation_id": operation_id}) # Get all collections collections = list_ansible_collections(db) # Apply any filters from criteria filter_criteria = arguments.get("filter_criteria", {}) if filter_criteria and "name_pattern" in filter_criteria: pattern = re.compile(filter_criteria["name_pattern"]) collections = [c for c in collections if pattern.match(c["name"])] # Format output if not collections: return [TextContent(type="text", text="No collections found")] output = ["Available Ansible Collections:"] for c in collections: output.append( f"\n- {c['name']} v{c['version']}" f"\n Modules: {c['module_count']}" f"\n Updated: {c['updated_at']}" f"\n Latest Module Update: {c.get('latest_module_update', 'N/A')}" f"\n Docs: {c['doc_url']}" ) return [TextContent(type="text", text="\n".join(output))] except Exception as e: error_msg = f"Failed to list collections: {str(e)}" logger.error(error_msg, extra={"operation_id": operation_id}) raise McpError( types.ErrorData( code=types.INTERNAL_ERROR, message=error_msg, data={ "tool": "list_ansible_collections", "operation_id": operation_id, }, ) )
