Buffer MCP Server
# buffer-mcp — Buffer 社媒发布 MCP 服务器
[](https://mcpservers.org/servers/wjjnew123/buffer-mcp)
通过 Buffer 统一发布/排期到 **Facebook、Instagram、YouTube** 等渠道,内置 **Cloudinary** 媒体上传与校验,共 **24 个工具**。帮助运营与办公场景实现 **AI 自动化**(内容排期、批量发布、媒体处理与数据分析)。
- 远程端点:`https://mcpweb.wjjnew.cn/buffer-mcp/mcp`(Streamable HTTP)
- 鉴权:`Authorization: Bearer mcp_sk_xxx`(在 https://mcpweb.wjjnew.cn/ 注册获取)
- 使用文档:https://mcpweb.wjjnew.cn/buffer-mcp-guide.html
- 产品介绍:https://mcpweb.wjjnew.cn/buffer-mcp
## 特性
- **一条上传链路**:`cloudinary_upload` 把本地文件变成公网 HTTPS 地址;密钥只留在进程内,不回显。
- **发布前校验**:文本长度、各平台必填元数据、媒体类型、YouTube Shorts 方向规则在调用前检查。
- **发布前探测**:`media_probe` 检查 HTTPS / HEAD / Range / Content-Type / 大小,避免 Buffer 拒收媒体。
- **写操作安全**:写工具需 `confirm` 令牌;修改/删除还需 `allowDestructive=true`;HTTP 写入需 `allowWrites=true`。
- **无 ffmpeg**:MP4 宽高/时长直接解析 `moov` box。
- **双传输**:stdio 与 Streamable HTTP 共用同一套工具注册。
## 客户端配置(远程托管,推荐)
```json
{
"mcpServers": {
"buffer-mcp": {
"type": "http",
"url": "https://mcpweb.wjjnew.cn/buffer-mcp/mcp",
"headers": { "Authorization": "Bearer <你的 mcp_sk_xxx>" }
}
}
}
```
## 工具清单(24)
| 分组 | 工具 |
|---|---|
| 配置(3) | `buffer_get_config` `buffer_set_config` `buffer_reset_config` |
| 渠道(3) | `buffer_list_organizations` `buffer_list_channels` `buffer_get_channel` |
| 帖子(5) | `buffer_list_posts` `buffer_get_post` `buffer_create_post` `buffer_update_post` `buffer_delete_post` |
| 媒体(8) | `cloudinary_upload` `cloudinary_upload_batch` `cloudinary_link` `cloudinary_variants` `cloudinary_list_assets` `cloudinary_delete` `media_probe` `media_preflight` |
| 分析(5) | `buffer_list_daily_limits` `buffer_get_analytics` `buffer_list_ideas` `buffer_list_idea_groups` `buffer_create_idea` |
> `cloudinary_list_assets` 支持 `resourceType`、`type`(默认 `upload`)、`maxResults`、`nextCursor`、`prefix`、`tags`、`direction`。
### 写操作确认
| 工具 | `confirm` | 额外要求 |
|---|---|---|
| `buffer_create_post` | `"create"` | 允许写入 |
| `buffer_update_post` / `buffer_delete_post` | 帖子 id | 允许修改/删除 |
| `cloudinary_upload` / `cloudinary_upload_batch` | `"upload"` | 已配置 Cloudinary |
| `cloudinary_delete` | `public_id` | 允许修改/删除 |
## 会话与稳定性(HTTP)
- SaaS 托管默认 `MCP_HTTP_STATELESS=true`:不依赖 `Mcp-Session-Id`,服务端重启/会话过期不会出现 `Session not found`;客户端携带旧 session id 会被直接忽略。
- 本地需要**有状态会话**时保持默认(不设置该变量)即可;此时服务端重启后客户端应重新 `initialize`。
## 本地运行
```bash
npm ci
npm run build
# stdio(默认)
BUFFER_API_KEY=你的Key node dist/index.js
# Streamable HTTP
BUFFER_API_KEY=你的Key MCP_TRANSPORT=http MCP_HTTP_PORT=8787 node dist/index.js
```
客户端(stdio):
```json
{
"mcpServers": {
"buffer-mcp": {
"command": "node",
"args": ["/path/buffer-mcp/dist/index.js"],
"env": { "BUFFER_API_KEY": "你的Key" }
}
}
}
```
## 配置
- 环境变量示例:`.env.example`
- 完整配置说明:`CONFIG.md`
- 配置示例:`buffer-mcp.config.example.json`
**Cloudinary 需自备**(`CLOUDINARY_CLOUD_NAME` / `CLOUDINARY_API_KEY` / `CLOUDINARY_API_SECRET`,或 `CLOUDINARY_URL`);未配置时不启用上传,可改用公网媒体 URL 发布。代码中的默认值为空,不会回退到任何第三方账号。
## 要求
- Node.js >= 20
- Buffer 个人 API Key(Buffer 后台 → Developers / API)
- 可选:Cloudinary 账号(仅本地上传需要)

Scored across 23 tools
Most tools are clearly distinct by resource and action (buffer_get_channel vs buffer_list_channels, buffer_get_post vs buffer_create_post). Minor overlap exists between media_probe and media_preflight (both validate media) and between cloudinary_upload and cloudinary_upload_batch, but descriptions clarify the single-vs-batch and URL-vs-channel-rule distinctions. An agent can reliably select the right tool.
Predictable verb_noun pattern with consistent domain prefixes (buffer_, cloudinary_, media_). Verbs (get/set/list/create/update/delete/upload) are used consistently. Minor deviations: cloudinary_link and cloudinary_variants omit a trailing noun, and buffer_get_analytics/buffer_list_daily_limits slightly break the resource_verb pattern, but overall readable and consistent.
23 tools is on the heavy side, spanning config, posts, media, analytics, and ideas domains. Each tool earns its place within its sub-domain, but the surface is large enough that it borders on overwhelming for a single server. Reasonable but at the upper edge of comfortable scoping.
Posts have full CRUD, config is fully manageable, and media/Cloudinary lifecycle is covered. Gaps: ideas only support list/list-groups/create with no update or delete, analytics is read-only, and channel management is read-only. These are minor gaps agents can work around for core Buffer workflows.
