update_article

Instructions

Implementation Reference

• src/index.ts:679-725 (handler)

  The handler function for the 'update_article' tool. It destructures the arguments (id, title, body, description, state, author_id, translated_content), validates the required 'id' field, builds a payload with only the provided fields, ensures at least one field is provided, calls the Intercom API via PUT /articles/{id}, and returns the updated article JSON.

  if (name === 'update_article') {
    const { id, title, body, description, state, author_id, translated_content } = args as {
      id: string;
      title?: string;
      body?: string;
      description?: string;
      state?: 'draft' | 'published';
      author_id?: number;
      translated_content?: {
        [locale: string]: {
          title?: string;
          body?: string;
          description?: string;
          state?: 'draft' | 'published';
        }
      }
    };
  
    // 驗證必填欄位
    if (!id) {
      throw new Error('Article ID is required');
    }
  
    // 建構 update payload（只包含提供的欄位）
    const payload: any = {};
  
    if (title) payload.title = title;
    if (body) payload.body = body;
    if (description) payload.description = description;
    if (state) payload.state = state;
    if (author_id) payload.author_id = author_id;
    if (translated_content) payload.translated_content = translated_content;
  
    // 確保至少有一個欄位要更新
    if (Object.keys(payload).length === 0) {
      throw new Error('At least one field must be provided for update');
    }
  
    const article = await callIntercomAPI(`/articles/${id}`, 'PUT', payload);
  
    return {
      content: [{
        type: 'text',
        text: JSON.stringify(article, null, 2)
      }]
    };
  }

• src/index.ts:270-328 (schema)

  name: 'update_article',

              description: 'Updated translated title'
            },
            body: {

              description: 'Updated translated content in HTML'
            },
            description: {
              type: 'string',

• src/index.ts:269-270 (registration)

  The tool registration entry in the tools array returned by ListToolsRequestSchema. The 'update_article' tool is listed with its name, description, and inputSchema, making it available to MCP clients.

  {
    name: 'update_article',

• src/index.ts:113-145 (helper)

  The callIntercomAPI helper function used by the handler to make the HTTP PUT request to Intercom's API at /articles/{id}.

  async function callIntercomAPI(
    endpoint: string,
    method: 'GET' | 'POST' | 'PUT' | 'DELETE' = 'GET',
    body?: any
  ): Promise<any> {
    const options: RequestInit = {
      method,
      headers: {
        'Authorization': `Bearer ${INTERCOM_TOKEN}`,
        'Accept': 'application/json',
        'Content-Type': 'application/json',
        'Intercom-Version': '2.14'
      }
    };
  
    if (body && (method === 'POST' || method === 'PUT')) {
      options.body = JSON.stringify(body);
    }
  
    const response = await fetch(`${INTERCOM_API_BASE}${endpoint}`, options);
  
    if (!response.ok) {
      const error = await response.text();
      throw new Error(`Intercom API error: ${response.status} - ${error}`);
    }
  
    // Handle 204 No Content response
    if (response.status === 204) {
      return { success: true };
    }
  
    return response.json();
  }
