Implementation Reference
- src/handlers/index.ts:295-319 (handler)The main handler logic for the 'list_memory_labels' tool, which queries Neo4j to retrieve all unique memory labels with their counts and returns the result as JSON.
case 'list_memory_labels': { if (!isListMemoryLabelsArgs(args)) { throw new McpError(ErrorCode.InvalidParams, 'Invalid list_memory_labels arguments'); } const query = ` MATCH (memory) WITH labels(memory) as nodeLabels UNWIND nodeLabels as label WITH label, count(*) as count ORDER BY count DESC, label RETURN collect({label: label, count: count}) as labels, sum(count) as totalMemories `; const result = await neo4j.executeQuery(query, {}); return { content: [ { type: 'text', text: JSON.stringify(result, null, 2), }, ], }; } - src/tools/definitions.ts:173-181 (registration)Tool registration in the tools array, defining name, description, and input schema.
{ name: 'list_memory_labels', description: 'List all unique memory labels currently in use with their counts (useful for getting an overview of the knowledge graph)', inputSchema: { type: 'object', properties: {}, required: [], }, }, - src/types.ts:51-53 (schema)TypeScript interface defining the expected arguments for list_memory_labels (empty object).
export interface ListMemoryLabelsArgs { // No arguments needed for this tool } - src/types.ts:115-118 (schema)Type guard function for validating list_memory_labels arguments.
export function isListMemoryLabelsArgs(args: unknown): args is ListMemoryLabelsArgs { // This tool doesn't require any arguments, so just check it's an object return typeof args === 'object' && args !== null; }
