Overview

The opentweetio/mcp-server MCP server connects AI assistants to X (Twitter) through OpenTweet's hosted or local MCP deployment. It provides tools for creating, publishing, scheduling, and managing tweets and threads, along with analytics, media generation, evergreen queues, and multiple accounts. Use it when an agent needs structured X publishing workflows without configuring an X developer account or OAuth app. Hosted access uses a Streamable HTTP endpoint and an OpenTweet API key, while local installation runs through npm.

Use cases

  • Schedule tweets and threads across a week
  • Repurpose blog content into an X thread
  • Review top posts and profile growth
  • Maintain an evergreen publishing queue
  • Manage multiple connected X accounts

Key features

  • Tweet and thread creation, editing, publishing, and scheduling
  • Batch scheduling for up to 50 posts
  • Analytics, growth, best-time, and content-gap tools
  • AI image and video generation
  • Evergreen queue management
  • Multi-account support with x_account_id

How MCP Server works

What opentweetio/mcp-server does

The opentweetio/mcp-server MCP server gives MCP-compatible AI clients tools for managing an X (Twitter) presence through OpenTweet. Its coverage includes tweet creation and editing, thread creation, publishing, deletion, scheduling, batch scheduling, and repurposing existing posts.

The toolset also includes media upload and AI image or video generation. For measurement and planning, it exposes analytics, top-post reporting, profile growth, best-time analysis, content-gap analysis, and inspiration search. Account tools support account details and account listing, while an evergreen queue can store, update, remove, and review reusable posts and their history.

MCP resources provide account status and the scheduled queue. Built-in prompts are also available. Multi-account operations can use an x_account_id value with tools that support it.

How it works

The opentweetio/mcp-server MCP server can be used as a hosted Streamable HTTP service or run locally through the npm package. The hosted endpoint is https://mcp.opentweet.io/mcp; clients authenticate with an OpenTweet API key sent as a bearer token. The key uses the ot_ prefix and is obtained from the OpenTweet developer page. An X account is connected once in the OpenTweet dashboard.

For local use, the package is launched with npx -y @opentweet/mcp-server. The MCP client sends tool calls to the configured server, and OpenTweet handles the X connection.

Setup and configuration

The hosted option requires no local installation. Add the Streamable HTTP URL to the MCP client's server configuration and include an Authorization header containing the OpenTweet key. Claude Code can add the server with its claude mcp add command.

For local npm deployment, run the interactive installer:

Terminal
npx -y @opentweet/mcp-server install

Alternatively, configure an MCP server with npx as the command and set OPENTWEET_API_KEY to the ot_ key. The README identifies standard configuration paths for Claude Desktop, Cursor, and Windsurf. A Claude Desktop extension is also available as an .mcpb download; its API key is stored in the operating system keychain.

Tools and capabilities

The opentweetio/mcp-server MCP server groups its 30 tools into these areas:

  • Tweets and threads: create, list, retrieve, update, delete, publish, schedule, batch schedule, and repurpose posts.
  • Media: upload media and generate images or videos.
  • Analytics: inspect analytics, top posts, profile growth, best posting times, content gaps, and inspiration.
  • Accounts: retrieve account details and list available accounts.
  • Evergreen queue: read settings, change settings, manage queued posts, and inspect queue history.

Batch scheduling supports up to 50 posts at once. Example workflows include turning a blog post into a scheduled thread, reviewing top posts, adding a post to the evergreen queue, and drafting content around identified gaps.

Limitations and notes

This listing documents the OpenTweet-managed connection rather than direct access to the X API. An OpenTweet API key and a connected X account are still needed for authenticated use.

The available client interfaces depend on the deployment method: hosted access uses Streamable HTTP, while the npm option uses a local process.
