Welder for Claude Code
Paste one message and Claude Code sets Welder up by itself, or follow the steps below.
Paste one message into Claude Code
Get your personal setup prompt and send it to Claude Code. It adds Welder and checks the connection by itself.
- Get your prompt. We sign you in first if needed.
- Paste it into Claude Code and send it.
- Say yes if it asks for permission, and restart it if it asks.
Connect Welder to yourself so you can post to my social media.MCP server: https://weldergtm.com/mcp (Streamable HTTP)Header: Authorization: Bearer your personal key
- Before you run anything or change any settings, ask me one short yes/no question, like "Connect Welder so I can post for you?", and wait for my yes. I'm not technical, so keep your replies short and simple.
- Then add this server as "welder" the way your app does it, for all my projects (not just this folder). Steps for each app and a connection check: https://weldergtm.com/setup.md
- Check that it works right away: call Welder's get_context tool, or, if new tools only load after a restart, run the connection check from that page.
- Tell me Welder is connected, which of my social accounts you can post to, and whether I need to restart you.
Only if you are a chat app that cannot run any commands (for example ChatGPT or the Claude app): don't use the key, and tell me how to add https://weldergtm.com/mcp as a custom connector in your own settings instead.
Keep this key private and never show it back to me.
Or set it up yourself

AskWhich accounts can you post to with Welder?Claude Codelatte-shopWhich accounts can you post to with Welder?
Welder is connected. You can post to these accounts:
TikTok Instagram
Or install the Welder plugin
Same connection, plus five ready-made workflows: getting started, publishing, scheduling, reviewing results and replying to your audience. Type these inside Claude Code, not in a terminal.
- Public package
- github.com/smvls/welder-plugins
- Name
- Welder: TikTok, Instagram & YouTube Autoposting
Directory listings. The Claude and ChatGPT plugin directories each review and approve a plugin before listing it. Meanwhile, install from the public repository or connect Welder directly.

Add the Welder marketplace, then install the plugin.
In Claude Code, one line at a time/plugin marketplace add smvls/welder-plugins /plugin install welder-social-manager@welder-plugins - 2

The usual fixes. If none helps, write to hello@weldergtm.com.
Claude Code says Welder needs you to sign in
Run /mcp inside Claude Code, pick welder and choose Authenticate. A browser tab opens; sign in and allow access.
Your app doesn’t see Welder
Quit the app completely and open it again after adding Welder; most apps only read their settings when they start. Then ask it which accounts it can post to.
I added it in the wrong scope
claude mcp remove welder, then add it again. Add --scope user to make Welder available in every project.
Welder says publishing is unavailable
Your Welder account can’t post right now. Check Billing in the Welder app at weldergtm.com, then ask again. Connecting accounts, uploading and checking a post work either way.
Prefer to use a key instead?For a machine without a browser. Create one under Advanced → Keys in the app; it is shown once.
Add Welder with your key as a header:
claude mcp add --transport http welder https://weldergtm.com/mcp --header "Authorization: Bearer {key}"
