Welder says posting more isn’t included

Your first 3 posts are free. After that, posting needs a plan: start your 3-day free trial 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, add a header:

~/.kiro/settings/mcp.json
{
  "mcpServers": {
    "welder": {
      "url": "https://weldergtm.com/mcp",
      "headers": { "Authorization": "Bearer {key}" }
    }
  }
}
