MCP Memory Server

Instructions

Implementation Reference

• src/memory-manager.ts:145-160 (handler)

  Core implementation of addSessionStep that loads project memory, creates a SessionStep object with step details, files modified, and optional description, appends it to current session's completedSteps, saves the memory, and logs success.

  async addSessionStep(step: string, filesModified: string[], description?: string): Promise<void> {
    const memory = await this.getProjectMemory();
    
    const sessionStep: SessionStep = {
      step,
      completed: new Date().toISOString(),
      filesModified,
      description,
      timeSpent: 0 // Could be calculated if needed
    };
  
    memory.currentSession.completedSteps.push(sessionStep);
    await this.saveProjectMemory(memory);
    
    console.log(chalk.green(`✅ Step completed: ${step}`));
  }

• src/index.ts:795-800 (handler)

  MCP server tool handler for 'add_session_step' that extracts parameters from request arguments, calls memoryManager.addSessionStep, and returns success response.

  case 'add_session_step': {
    const step = args.step as string;
    const filesModified = args.filesModified as string[];
    const description = args.description as string | undefined;
    await this.memoryManager.addSessionStep(step, filesModified, description);
    return { content: [{ type: 'text', text: 'Session step added successfully' }] };

• src/index.ts:567-578 (registration)

  Registration of the 'add_session_step' tool in the MCP server's ListTools handler, including name, description, and input schema definition.

    name: 'add_session_step',
    description: 'Record completion of a step in the current session',
    inputSchema: {
      type: 'object',
      properties: {
        step: { type: 'string', description: 'Description of the completed step' },
        filesModified: { type: 'array', items: { type: 'string' }, description: 'List of files that were modified' },
        description: { type: 'string', description: 'Optional detailed description' }
      },
      required: ['step', 'filesModified']
    }
  },

• src/index.ts:569-576 (schema)

  Input schema definition for the add_session_step tool, specifying required 'step' and 'filesModified' fields, and optional 'description'.

  inputSchema: {
    type: 'object',
    properties: {
      step: { type: 'string', description: 'Description of the completed step' },
      filesModified: { type: 'array', items: { type: 'string' }, description: 'List of files that were modified' },
      description: { type: 'string', description: 'Optional detailed description' }
    },
    required: ['step', 'filesModified']
