Welder for Claude
Add Welder as a custom connector, then connect it. Works on every Claude plan (Free allows one custom connector).
Steps
Why the settings, not a message?
Claude can’t add tools from inside a chat, so you add Welder once in its settings and sign in. There’s no key to copy. If you pasted a Welder setup prompt, Claude walks you through these same steps.
- 1
In Claude, open Customize → Connectors.
- 2
Click + and choose Add custom connector. Paste the Welder link and click Add.

The usual fixes. If none helps, write to hello@weldergtm.com.
I cannot find custom connectors
Open Customize in the left sidebar, then Connectors. On a Team or Enterprise plan, an owner adds Welder once under Organization settings → Connectors, then you click Connect.
Claude does not use Welder
Open the + menu in the chat, choose Connectors and switch Welder on for that conversation.
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.
