  description: Official hosted Weld MCP server. Lets AI assistants (Claude Desktop, claude.ai, Claude
    Code, Cursor, GitHub Copilot, Windsurf, and other MCP clients) interact directly with a Weld workspace
    — listing syncs, inspecting connections, debugging failures, creating transforms, and orchestrating
    pipelines via natural language.
authentication:
  methods:
  - type: oauth
    recommended: true
    notes: MCP OAuth flow; supported by Claude Desktop, claude.ai, and Claude Code. No API key required
      — browser login authorizes the connection and scopes it to your Weld account/workspace.
  - type: api_key
    header: x-api-key
    notes: For clients without OAuth or programmatic/headless use. Workspace-scoped key created under
      Settings -> API keys in the Weld app.
