概覽

AI 產生的概覽

讓助理用你儲存的語氣草擬、排程並發布 X 和 LinkedIn 貼文，並研究高成效的 X 貼文。

功能
Postel 是一個託管的 MCP 伺服器，用於撰寫和排程社群貼文。工具涵蓋貼文生命週期：list-posts、get-post、create-post、update-post、delete-post、schedule-post 和 publish-post。寫作工具 generate-post 和 refine-post 會依你儲存的語氣草擬 X 貼文、X 長串文或 LinkedIn 貼文，search-viral-tweets 則從 Postel 的索引資料庫中依主題尋找高成效的 X 貼文。情境工具提供品牌、語氣設定檔、每週發布時段和用量限制。
適用情境
如果你以個人身分在 X 或 LinkedIn 發文，並希望助理研究開頭鉤子、草擬貼文和長串文，並在你核准後排程或發布，這個伺服器適合你。它面向已使用 Postel 排程的創辦人、顧問和創作者。它不用於讀取時間軸、提及或私訊，也不做互動操作。
執行需求
遠端 Streamable HTTP 端點，本機不需執行任何東西。研究功能不需要帳號。其他功能需要 Postel 帳號，並連接 X 帳號、LinkedIn 個人檔案或兩者。驗證方式為 OAuth 2.1 加動態用戶端註冊，或以 Authorization bearer token 形式傳送 API 金鑰。排程和發布需要付費方案或試用。
安裝前請注意
此伺服器可以發布到你真實的 X 帳號和個人 LinkedIn 個人檔案，並刪除貼文及其排程，因此核准前請檢查草稿。它需要帳號存取權，以及 OAuth 登入或 Authorization 標頭中的 API 金鑰；金鑰以工作區為範圍，且限制為每分鐘 60 次請求。AI 生成會消耗每月配額。LinkedIn 貼文僅發布到個人檔案，圖片、影片和第一則留言需在 Postel 編輯器中加入。

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.
