Implementation Reference

• src/tools/handlers.ts:104-120 (handler)

  MCP tool handler for 'get_session_summary' that extracts optional sessionId from args, calls thinkingManager.getSessionSummary, and returns JSON-formatted summary or throws if session not found.

  case 'get_session_summary': {
    const { sessionId } = args as { sessionId?: string };
    const summary = thinkingManager.getSessionSummary(sessionId);
  
    if (!summary) {
      throw new Error('Session not found');
    }
  
    return {
      content: [
        {
          type: 'text',
          text: JSON.stringify(summary, null, 2),
        },
      ],
    };
  }

• src/tools/definitions.ts:97-109 (schema)

  Tool schema definition for 'get_session_summary' including name, description, and inputSchema allowing optional sessionId.

  export const GET_SESSION_SUMMARY_TOOL: Tool = {
    name: 'get_session_summary',
    description: 'Gets a summary of the current or specified thinking session',
    inputSchema: {
      type: 'object',
      properties: {
        sessionId: {
          type: 'string',
          description: 'Optional session ID (defaults to current session)',
        },
      },
    },
  };

• src/lib.ts:190-211 (helper)

  Core helper method in SequentialThinkingManager that computes and returns session summary statistics (thoughtCount, branchCount, timestamps) for given or current sessionId.

  public getSessionSummary(sessionId?: string): {
    sessionId: string;
    thoughtCount: number;
    branchCount: number;
    createdAt: number;
    updatedAt: number;
  } | null {
    const sid = sessionId || this.currentSessionId;
    const session = this.sessions.get(sid);
  
    if (!session) {
      return null;
    }
  
    return {
      sessionId: session.sessionId,
      thoughtCount: session.thoughts.length,
      branchCount: session.branches.size,
      createdAt: session.createdAt,
      updatedAt: session.updatedAt,
    };
  }
