Fabric MCP Server

Instructions

Implementation Reference

• src/index.ts:92-135 (handler)

  The handler logic for executing the 'recommend_tool'. It extracts the task from input, simulates a Perplexity recommendation (currently hardcoded to 'summarize'), and returns the recommended tool name.

   if (request.params.name === "recommend_tool") {
     const task = String(request.params.arguments?.input || '');
  
     // Use Perplexity to recommend a Fabric pattern
     // Call the Perplexity MCP server to search for the best Fabric pattern
     let recommendedTool = "summarize"; // default tool
     try {
       const perplexityResult = await new Promise<any>((resolve, reject) => {
    //server.accessResource({
         //  serverName: "github.com/pashpashpash/perplexity-mcp",
         //  uri: `search?query=Recommend the best Fabric pattern tool for the task: ${task}. Choose from the following patterns: ${patterns.join(', ')}&detail_level=brief`
         //}).then((result: any) => {
         //  console.error('Perplexity recommendation:', result);
         //  if (result && result.content && result.content[0] && result.content[0].text) {
         //    recommendedTool = result.content[0].text;
         //  } else {
         //    console.error("Unexpected result format from perplexity-mcp:", result);
         //  }
         //  resolve(result);
         //}).catch((error: any) => {
         //  console.error("Error calling perplexity-mcp:", error);
         //  reject(error);
         //});
         console.error("Calling perplexity-mcp to recommend a tool");
  recommendedTool = "summarize";
         resolve({content: [{text: "summarize"}]});
       });
  
       return {
         content: [{
           type: "text",
           text: `Recommended tool: ${recommendedTool}`
         }]
       };
     } catch (error) {
       console.error("Error calling perplexity-mcp:", error);
       return {
         content: [{
           type: "text",
           text: `Error calling perplexity-mcp: ${error}`
         }]
       };
     }
   }

• src/index.ts:68-82 (registration)

  Registers the 'recommend_tool' in the ListTools response by adding it to the tools array, including its description and input schema.

  // Add the recommend_tool
  tools.push({
    name: "recommend_tool",
    description: "Recommends the best Fabric pattern tool for a given task",
     inputSchema: {
       type: "object",
       properties: {
         input: {
           type: "string",
           description: "The user's task description"
         }
       },
       required: ["input"]
     }
  });
