Implementation Reference

• src/server.js:58-71 (registration)

  Registration of the 'check_api_keys' MCP tool. Includes empty input schema, inline handler function that retrieves API key status via apiKeyManager.getStatus() and returns it as JSON text content, and tool description.

  server.tool(
    "check_api_keys",
    {},
    async () => {
      const status = apiKeyManager.getStatus();
      return {
        content: [{ 
          type: "text", 
          text: JSON.stringify(status, null, 2)
        }]
      };
    },
    { description: "Check the status of your API keys" }
  );

• src/modules/api-key-manager.js:79-90 (helper)

  ApiKeyManager.getStatus() method called by the tool handler. Returns a status object with masked API keys for OpenAI and YouTube, indicating if set and partial key for verification.

  getStatus() {
    return {
      openai: {
        set: this.hasOpenAIKey(),
        key: this.hasOpenAIKey() ? "********" + this.openaiApiKey.slice(-4) : null
      },
      youtube: {
        set: this.hasYouTubeKey(),
        key: this.hasYouTubeKey() ? "********" + this.youtubeApiKey.slice(-4) : null
      }
    };
  }
