Welder for Gemini CLI
Paste one message and Gemini CLI sets Welder up by itself, or follow the steps below.
Paste one message into Gemini CLI
Get your personal setup prompt and send it to Gemini CLI. It adds Welder and checks the connection by itself.
- Get your prompt. We sign you in first if needed.
- Paste it into Gemini CLI 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
One command adds Welder over HTTP. Sign in when Gemini asks.

Didn’t work?
The usual fixes. If none helps, write to hello@weldergtm.com.
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.
No browser window opened to sign in
Sign in at weldergtm.com in your default browser first, then try again. If your app can’t open a browser (on a remote machine, for example), use a key instead.
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.
With a key, use ~/.gemini/settings.json:
{
"mcpServers": {
"welder": {
"httpUrl": "https://weldergtm.com/mcp",
"headers": { "Authorization": "Bearer {key}" }
}
}
}
