MCP Think Tool Server

Instructions

Implementation Reference

• src/index.ts:58-72 (handler)

  Handler function for 'get_thoughts' tool: checks if thoughtsLog is empty, if so returns a message; otherwise formats all thoughts with timestamps and indices into a text response.

  async () => {
    if (this.thoughtsLog.length === 0) {
      return {
        content: [{ type: "text", text: "No thoughts have been recorded yet." }]
      };
    }
    
    const formattedThoughts = this.thoughtsLog.map((entry, index) => 
      `Thought #${index + 1} (${entry.timestamp}):\n${entry.thought}\n`
    );
    
    return {
      content: [{ type: "text", text: formattedThoughts.join("\n") }]
    };
  }

• src/index.ts:54-73 (registration)

  Registration of the 'get_thoughts' tool via this.server.tool(), including name, description (no input schema), and inline handler function.

  // Register the get_thoughts tool
  this.server.tool(
    "get_thoughts",
    "Retrieve all thoughts recorded in the current session to review your reasoning process.",
    async () => {
      if (this.thoughtsLog.length === 0) {
        return {
          content: [{ type: "text", text: "No thoughts have been recorded yet." }]
        };
      }
      
      const formattedThoughts = this.thoughtsLog.map((entry, index) => 
        `Thought #${index + 1} (${entry.timestamp}):\n${entry.thought}\n`
      );
      
      return {
        content: [{ type: "text", text: formattedThoughts.join("\n") }]
      };
    }
  );

• src/index.ts:8-11 (helper)

  Interface defining the structure of each thought record stored in thoughtsLog, used by the get_thoughts handler.

  interface ThoughtRecord {
    timestamp: string;
    thought: string;
  }

• src/index.ts:14-14 (helper)

  Private array storing all ThoughtRecord entries, which the get_thoughts handler reads from.

  private thoughtsLog: ThoughtRecord[] = [];
