Implementation Reference
- src/index.ts:475-488 (handler)The main handler for the 'check_api_key' tool. It attempts to retrieve the API key via authManager.getAccessToken(), masks it for display if successful, or returns a message indicating no key is configured.
case 'check_api_key': { try { const token = await this.authManager.getAccessToken(); // 只显示部分API key作为安全措施 const maskedToken = token.substring(0, 5) + '...' + token.substring(token.length - 5); return { content: [{ type: 'text', text: `API key is configured (${maskedToken})` }], }; } catch (error) { return { content: [{ type: 'text', text: 'No API key is configured. Please use set_api_key to configure one.' }], }; } } - src/index.ts:105-112 (schema)Tool schema definition for 'check_api_key', specifying name, description, and empty input schema (no arguments required).
{ name: 'check_api_key', description: 'Check if a Figma API key is already configured', inputSchema: { type: 'object', properties: {}, required: [] }, - src/utils/auth.ts:32-54 (helper)Core logic for retrieving the configured Figma API key from AuthManager. Loads from config if needed and throws an error if no key is available.

Use the set_api_key tool first.' ); } // 返回API key作为令牌 return this.apiKey; } - src/utils/auth.ts:10-18 (helper)AuthManager constructor initializes by loading any saved API key from config.
