Overview

AI-generated overview

CrossPoster lets an assistant draft, preview, schedule and publish social posts to X, LinkedIn, Bluesky and five more networks.

What you can do
  • Draft social media posts for multiple networks
  • Preview posts before they go out
  • Schedule posts for later publishing
  • Publish posts to X, LinkedIn, Bluesky and five other social networks
When to use it
Useful when you want an assistant to help compose, queue and publish social media content across several networks from one place, rather than writing and posting each one by hand.
Requirements
A remote MCP endpoint at mcp.crossposter.tech, reached over streamable HTTP. OAuth authentication is required, so a CrossPoster account and an OAuth sign-in flow are needed. No environment variables or headers are declared.
Before you install
The server can publish and schedule posts on connected social accounts, so content may go public without further review. OAuth access grants it rights over those accounts; check which networks are connected and revoke access if no longer needed.

Installation

In SourceWeft

  1. Open CrossPoster in the dashboard and add it to a workspace.
  2. Connect the required credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/tech.crossposter%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

  "mcpServers": {
    "crossposter": {

      "url": "https://mcp.crossposter.tech/mcp"

Tools

0
This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
