Sequential Thinking MVP Server

Instructions

Implementation Reference

• src/tools/handlers.ts:84-102 (handler)

  Switch case handling the reset_thinking_session tool: calls resetSession on the thinking manager and returns confirmation with new session ID.

  case 'reset_thinking_session': {
    const newSessionId = thinkingManager.resetSession();
  
    return {
      content: [
        {
          type: 'text',
          text: JSON.stringify(
            {
              message: 'New thinking session started',
              sessionId: newSessionId,
            },
            null,
            2
          ),
        },
      ],
    };
  }

• src/tools/definitions.ts:88-95 (schema)

  Tool schema definition for reset_thinking_session with name, description, and empty input schema (no parameters required).

  export const RESET_SESSION_TOOL: Tool = {
    name: 'reset_thinking_session',
    description: 'Starts a new thinking session, clearing the current thought sequence',
    inputSchema: {
      type: 'object',
      properties: {},
    },
  };

• src/lib.ts:180-184 (helper)

  Core implementation of session reset in SequentialThinkingManager: generates new secure session ID and initializes empty session.

  public resetSession(): string {
    this.currentSessionId = generateSecureSessionId();
    this.initializeSession(this.currentSessionId);
    return this.currentSessionId;
  }

• src/index.ts:31-39 (registration)

  MCP server registration: lists tools via ALL_TOOLS (includes reset_thinking_session schema) and dispatches calls to shared handleToolCall function.

  // Handle tool listing
  server.setRequestHandler(ListToolsRequestSchema, async () => {
    return { tools: ALL_TOOLS };
  });
  
  // Handle tool calls
  server.setRequestHandler(CallToolRequestSchema, async (request) => {
    return handleToolCall(request.params, thinkingManager);
  });
