set_api_keys

Implementation Reference

• src/server.js:19-55 (registration)

  Registration of the 'set_api_keys' tool using McpServer.tool(). Includes input schema with Zod validation, the complete async handler function, and tool description.

  server.tool(
    "set_api_keys",
    { 
      openaiApiKey: z.string().min(1).describe("Your OpenAI API key"),
      youtubeApiKey: z.string().optional().describe("Your YouTube API key (optional)")
    },
    async ({ openaiApiKey, youtubeApiKey }) => {
      try {
        apiKeyManager.setOpenAIKey(openaiApiKey);
        if (youtubeApiKey) {
          apiKeyManager.setYouTubeKey(youtubeApiKey);
        }
        
        return {
          content: [{ 
            type: "text", 
            text: JSON.stringify({
              success: true,
              message: "API keys set successfully. You can now use the other tools."
            }, null, 2)
          }]
        };
      } catch (error) {
        return {
          content: [{ 
            type: "text", 
            text: JSON.stringify({
              success: false,
              error: error.message
            }, null, 2)
          }],
          isError: true
        };
      }
    },
    { description: "Set your API keys for OpenAI and YouTube (optional)" }
  );

• src/server.js:25-53 (handler)

  Handler function that receives API keys, calls ApiKeyManager.set* methods, and returns MCP-formatted text response with JSON payload indicating success or error.

  async ({ openaiApiKey, youtubeApiKey }) => {
    try {
      apiKeyManager.setOpenAIKey(openaiApiKey);
      if (youtubeApiKey) {
        apiKeyManager.setYouTubeKey(youtubeApiKey);
      }
      
      return {
        content: [{ 
          type: "text", 
          text: JSON.stringify({
            success: true,
            message: "API keys set successfully. You can now use the other tools."
          }, null, 2)
        }]
      };
    } catch (error) {
      return {
        content: [{ 
          type: "text", 
          text: JSON.stringify({
            success: false,
            error: error.message
          }, null, 2)
        }],
        isError: true
      };
    }
  },

• src/server.js:21-24 (schema)

  Zod-based input schema for the tool: requires OpenAI API key as non-empty string, optional YouTube API key.

  { 
    openaiApiKey: z.string().min(1).describe("Your OpenAI API key"),
    youtubeApiKey: z.string().optional().describe("Your YouTube API key (optional)")
  },

• src/modules/api-key-manager.js:23-29 (helper)

  Helper method in ApiKeyManager class to validate and store the OpenAI API key, called from the tool handler.

  setOpenAIKey(key) {
    if (!key || typeof key !== 'string' || key.trim() === '') {
      throw new Error("Invalid OpenAI API key");
    }
    this.openaiApiKey = key.trim();
    console.log("OpenAI API key set successfully");
  }

• src/modules/api-key-manager.js:35-41 (helper)

  Helper method in ApiKeyManager class to validate and store the YouTube API key (optional), called from the tool handler.

  setYouTubeKey(key) {
    if (!key || typeof key !== 'string' || key.trim() === '') {
      throw new Error("Invalid YouTube API key");
    }
    this.youtubeApiKey = key.trim();
    console.log("YouTube API key set successfully");
  }
