Xpost

Registry nameto.xpost/xpost

Overview

Description from the maker (original English)

Post all your social media with your AI agent — 9 networks, from Claude, ChatGPT or Cursor.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Marketing & social media

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Works in Claude on the web, desktop and mobile:

  1. Open Settings → Connectors
  2. Press Add custom connector
  3. Paste the address below and press Add
  4. If it asks you to sign in, sign in with the maker
SettingsConnectors1+ Add2https://…3
https://xpost.to/api/mcp

Run this in your terminal

claude mcp add --transport http xpost https://xpost.to/api/mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "xpost": {
      "url": "https://xpost.to/api/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "xpost": {
      "type": "http",
      "url": "https://xpost.to/api/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker
SettingsConnectors1+ Create2https://…3
https://xpost.to/api/mcp

Menu names can differ slightly by plan and over time.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Compared with others in Marketing & social mediai

  • More stars than 0% of the other 2984 servers in this category
  • Published to the registry more recently than 56% of the other 2984 servers in this category
  • Basic checks equal to or better than 100% of the other 2984 servers in this category

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.

Common questions

Is Xpost safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.1) reached the registry 24 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

xpost for your assistant

Post all your social media with your AI agent: X, Instagram, LinkedIn, Facebook, TikTok, YouTube, Threads, Bluesky and Pinterest, from Claude, ChatGPT, Cursor, Gemini CLI or any MCP client. Want a say first? Switch on approvals and nothing goes out until a person says yes.

This repo is the open-source skill (the workflow an agent should follow) plus the plugin manifests that install it together with the hosted MCP server at https://xpost.to/api/mcp. You sign in once in a browser window; nothing to paste.

You need an xpost account — the first post is free, no card: https://xpost.to/signup

Install

Any agent — as a skill
npx skills add xpost-to/xpost-agent

This installs the skill only. Add the MCP server in your client as below, or let the skill's REST fallback use XPOST_API_KEY.

Claude Code — plugin (skill + MCP server)
/plugin marketplace add xpost-to/xpost-agent

/plugin install xpost@xpost-agent

Nothing prompts you to sign in: type /mcp, choose xpost, then Authenticate — your browser opens on the sign-in page. Or without the plugin:

claude mcp add --transport http xpost https://xpost.to/api/mcp
Gemini CLI — extension (skill + MCP server)
gemini extensions install https://github.com/xpost-to/xpost-agent

Gemini opens a browser to sign in to xpost on first use; /mcp auth xpost signs in again.

Cursor

One click: Add xpost to Cursor

Or add it by hand in Settings → Tools & Integrations → New MCP Server:

{ "mcpServers": { "xpost": { "type": "http", "url": "https://xpost.to/api/mcp" } } }

Then npx skills add xpost-to/xpost-agent for the skill. The repo also carries a Cursor plugin manifest (.cursor-plugin/plugin.json).

Grok Build

The repo carries a Grok Build plugin manifest (.grok-plugin/plugin.json, skill + hosted MCP server) and its own marketplace catalog (.grok-plugin/marketplace.json). Inside Grok Build, /marketplace browses the catalog; from a shell, grok plugin install xpost --trust once the source is known to it. Not yet in the official xAI index.

Muse Code (Meta)

Add the hosted server to ~/.config/muse/settings.json; Muse Code asks you to sign in on the first tool call:

{

"schema_version": 1, "mcp_servers": { "xpost": { "transport": "streamable_http", "url": "https://xpost.to/api/mcp" } } }

Grok, Muse and other chat assistants with no MCP settings

Paste this into the chat. The assistant sets itself up and asks you for an API key (Project → AI agent → Keys on xpost):

Set up xpost so you can post to my social accounts. The REST API is

https://xpost.to/api/v1 (spec at https://xpost.to/api/v1/openapi.json),

authenticated with an Authorization: Bearer YOUR_KEY header. If you can run

commands, npx xpost wraps it and npx skills add xpost-to/xpost-agent

installs the workflow. Ask me for my xpost API key and set it as

XPOST_API_KEY before doing anything. Start with the accounts list. Creating

a post sends it, unless my project holds posts for approval — never say a

post is published until the receipt says so.

ChatGPT, Claude.ai, Claude Desktop

ChatGPT: xpost is in the plugin directory — find it, add it, sign in. Claude with the xpost plugin installed: Customize → Connectors, find xpost, press Connect, sign in — the plugin brings the connector, signed out. Without the plugin: Customize → Connectors → Add → custom connector, paste https://xpost.to/api/mcp, sign in.

No MCP client at all — the CLI
npx xpost login

npx xpost posts create -c "Shipped it." -a x:yourhandle

The xpost package on npm is the CLI, the local MCP server (npx xpost mcp) and the skill's fallback in one. Docs: https://xpost.to/docs/cli

What the skill teaches

  • Accounts first: list_accounts names every destination and what it can carry.
  • get_posting_rules is the option catalog per account; a key that is not there cannot be used.
  • Creating a post sends it; a project in copilot mode holds it (pending_approval) instead. Either is a normal outcome — say which, print the link.
  • A guardrail refusal names the rule. Rewrite once. Never evade.
  • list_posts before assuming a post is still waiting — the person may have rejected it with a reason.
  • Receipts are per account: "delivered to X, failed on Instagram: reason".

Self-hosting a client against your own instance

Replace https://xpost.to with your instance in the MCP address. For the REST fallback set XPOST_URL and XPOST_API_KEY.
