概览

AI 生成的概览

让助手用你保存的语气起草、排期并发布 X 和 LinkedIn 帖子，并研究高表现的 X 帖子。

功能
Postel 是一个托管的 MCP 服务器，用于撰写和排期社交帖子。工具覆盖帖子生命周期：list-posts、get-post、create-post、update-post、delete-post、schedule-post 和 publish-post。写作工具 generate-post 和 refine-post 按你保存的语气起草 X 帖子、X 长帖或 LinkedIn 帖子，search-viral-tweets 则从 Postel 的索引库中按主题查找高表现的 X 帖子。上下文工具提供品牌、语气档案、每周发布时段和用量限制。
适用场景
如果你以个人身份在 X 或 LinkedIn 发帖，并希望助手研究钩子、起草帖子和长帖，并在你批准后排期或发布，这个服务器适合你。它面向已经使用 Postel 做排期的创始人、顾问和创作者。它不用于读取时间线、提及或私信，也不做互动操作。
运行要求
远程 Streamable HTTP 端点，本地无需运行任何东西。研究功能无需账号。其他功能需要 Postel 账号，并连接 X 账号、LinkedIn 个人资料或两者。认证方式为 OAuth 2.1 加动态客户端注册，或以 Authorization bearer token 形式发送 API 密钥。排期和发布需要付费方案或试用。
安装前请注意
该服务器可以向你的真实 X 账号和个人 LinkedIn 资料发布内容，并删除帖子及其排期，因此批准前请检查草稿。它需要账号访问权限，以及 OAuth 登录或 Authorization 头中的 API 密钥；密钥按工作区限定，且限制为每分钟 60 次请求。AI 生成会消耗每月配额。LinkedIn 帖子仅发到个人资料，图片、视频和首条评论需在 Postel 编辑器中添加。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Postel，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

README

Postel MCP server for X (Twitter) and LinkedIn

Draft, schedule and publish X (Twitter) and LinkedIn posts from Claude, Cursor and other MCP clients.

Postel is a writing and scheduling tool for people who post as themselves: founders, consultants and creators. Its hosted MCP server lets an AI assistant research high-performing X posts, draft posts and threads in your saved voice, and schedule or publish them to your X account and your personal LinkedIn profile once you approve.

This repository holds the public metadata for that server: the Claude plugin, the MCP Registry entry and setup instructions. The server itself is hosted by Postel; there is nothing to run locally.

Server URLhttps://www.postel.app/api/mcp
TransportStreamable HTTP
AuthenticationOAuth 2.1 with dynamic client registration, or an API key as a bearer token
Registry nameapp.postel/postel

Setup

Post research (search-viral-tweets) works without an account. For everything else you need a Postel account; connect your X account, your LinkedIn profile or both under Settings > Channels.

Claude Code plugin

/plugin marketplace add robinfaraj/postel-mcp/plugin install postel@postel

Then run /mcp and sign in to Postel. The plugin adds the server and a postel-writing skill that teaches Claude the drafting and scheduling workflow.

Claude Code without the plugin

bash
claude mcp add --transport http postel https://www.postel.app/api/mcp

Run /mcp to sign in. To use an API key instead:

bash
claude mcp add --transport http postel https://www.postel.app/api/mcp --header "Authorization: Bearer pstl_YOUR_API_KEY"

Claude (web and desktop)

Open Customize > Connectors, click +, choose Add custom connector, enter https://www.postel.app/api/mcp and sign in to Postel when asked.

Cursor

Add this to your MCP settings (~/.cursor/mcp.json or .cursor/mcp.json in a project):

json
{  "mcpServers": {    "postel": {      "url": "https://www.postel.app/api/mcp",      "headers": {        "Authorization": "Bearer pstl_YOUR_API_KEY"      }    }  }}

Create the key in Postel under Settings > API Keys. Keys start with pstl_ and are scoped to one workspace.

Other clients

Any client that supports remote MCP servers over Streamable HTTP works. Point it at the server URL above and either let it run the OAuth sign-in or send Authorization: Bearer pstl_YOUR_API_KEY.

Example prompts

  • "Find viral posts about bootstrapping a SaaS and tell me what the best hooks have in common."
  • "Draft a LinkedIn post about the pricing change we shipped this week."
  • "Write a thread about what we learned from our last launch."
  • "Show me what is scheduled for next week."
  • "Schedule that post for Tuesday at 9am Berlin time."

What it does not do

  • It does not read your X timeline, mentions or DMs, or your LinkedIn feed or messages.
  • It does not like, reply, follow, comment or send connection requests.
  • LinkedIn posts go to personal profiles only, not company pages.
  • Images, video, documents and LinkedIn first comments are added in the Postel editor, not through MCP.
  • Research searches Postel's indexed library of X posts, not live X.

Plans and limits

  • Research needs no account. Drafting and reading posts work on any plan, and AI generation counts against your monthly quota.
  • Scheduling and publishing need a paid plan or trial. See pricing.
  • API keys are limited to 60 requests per minute.
