Remote Memory MCP Server

Instructions

Implementation Reference

• src/index.ts:546-560 (handler)

  The MCP tool handler for 'search_nodes'. It calls memoryManager.searchNodes and returns formatted JSON response with search results.

  private async handleSearchNodes(args: any) {
    const results = this.memoryManager.searchNodes(args.query);
    
    return {
      content: [{
        type: 'text',
        text: JSON.stringify({
          success: true,
          query: args.query,
          results: results,
          count: results.length,
        }, null, 2),
      }],
    };
  }

• src/index.ts:217-223 (schema)

  Input schema defining the expected arguments for the search_nodes tool: a required 'query' string.

  inputSchema: {
    type: 'object',
    properties: {
      query: { type: 'string' },
    },
    required: ['query'],
  },

• src/index.ts:214-225 (registration)

  Registration of the search_nodes tool in the tools list returned by ListToolsRequestHandler, including name, description, and input schema.

  {
    name: 'search_nodes',
    description: '엔티티를 검색합니다',
    inputSchema: {
      type: 'object',
      properties: {
        query: { type: 'string' },
      },
      required: ['query'],
    },
  },
  {

• src/memory-graph.ts:122-139 (helper)

  Core helper method implementing the search logic: finds entities where query matches name, entityType, or any observation (case-insensitive).

  searchNodes(query: string): Entity[] {
    const searchTerm = query.toLowerCase();
    const results: Entity[] = [];
    
    this.graph.entities.forEach(entity => {
      const nameMatch = entity.name.toLowerCase().includes(searchTerm);
      const typeMatch = entity.entityType.toLowerCase().includes(searchTerm);
      const obsMatch = entity.observations.some(obs => 
        obs.toLowerCase().includes(searchTerm)
      );
      
      if (nameMatch || typeMatch || obsMatch) {
        results.push(entity);
      }
    });
    
    return results;
  }
