MCP Advanced Reasoning Server

Implementation Reference

• src/tools/reasoning-tools.ts:145-185 (handler)

  Handler function that implements the r1_reasoning tool logic: validates input prompt, generates simulated R1 Transformer-based reasoning output as JSON text content.

  async ({ prompt }) => {
    try {
      // Validate parameters
      if (!prompt) {
        throw new ValidationError("Prompt is required");
      }
      
      // In a real implementation, this would connect to an external R1 reasoning system
      // For now, we'll simulate the reasoning process
      
      // Simulated reasoning output
      const reasoning = `R1 Reasoning Analysis:\n\n` +
                        `For the prompt: "${prompt.slice(0, 100)}...", the analysis is:\n\n` +
                        `1. Initial problem parsing: [Simulated R1 analysis]\n` +
                        `2. Key observation: [Simulated R1 analysis]\n` +
                        `3. Proposed solution approach: [Simulated R1 analysis]\n` +
                        `4. Implementation details: [Simulated R1 analysis]\n` +
                        `5. Verification and testing: [Simulated R1 analysis]\n\n` +
                        `[This would be actual R1 Transformer-based reasoning content]`;

• src/tools/reasoning-tools.ts:142-144 (schema)

  Input schema for r1_reasoning tool using Zod: requires a 'prompt' string parameter.

  {
    prompt: z.string().describe("The problem or query to reason about")
  },

• src/tools/reasoning-tools.ts:140-186 (registration)

  Registration of the r1_reasoning tool on the MCP server within registerReasoningTools function.

  server.tool(

• src/index.ts:22-22 (registration)

  Top-level call to registerReasoningTools(server), which registers the r1_reasoning tool among others.

  registerReasoningTools(server);

• src/utils/errors.ts:19-24 (helper)

  ReasoningError class used in the r1_reasoning handler for error handling.

  export class ReasoningError extends Error {
    constructor(message: string) {
      super(message);
      this.name = "ReasoningError";
    }
  }
