Connect an AI client over MCP

Connect claude.ai, Claude Code, Cursor, or ChatGPT to WEXTL over the Model Context Protocol so an assistant can create, run, and inspect your workflows.

AI-assisted documentation

This documentation is compiled from our own product source code and internal specs, the platform's public API specification, and anonymized requests logs we collect from our support team[2].

Updates every sample URL on this page to your organization's regional host. Match the shard in your API key (wextl_<shard>_…).

You need an active WEXTL account and a way to authenticate the connection — a Personal Access Token for Claude Code or Cursor, or an OAuth sign-in for claude.ai and ChatGPT. See Authentication & scopes for the full model.[1]

Every organization gets a single regional MCP endpoint, scoped to its data-plane region. Pick your region with the control at the top of this page — samples update to match. Pattern: https://<shard>.wextl.com/api/mcp. Requests are authenticated the same way as the REST API — see Authentication & scopes.

This endpoint implements the Model Context Protocol — the same open specification every MCP-aware client understands, not a proprietary variant.[3]

Two ways to authenticate an MCP connection:

  • Personal Access Token (PAT) — fastest to set up; paste a token into a client that supports bearer-token MCP connections (Claude Code, Cursor).
  • OAuth 2.1 — required for the hosted claude.ai and ChatGPT custom connectors, which drive an interactive consent flow (org + scope picker) rather than accepting a pasted token.

Add WEXTL as a custom connector from claude.ai's connector settings using the MCP endpoint above. You'll be redirected through the OAuth consent screen to pick an organization and approve the scopes the connector requests.

Register the MCP endpoint with a Personal Access Token as a bearer credential in your Claude Code MCP configuration.

bash
claude mcp add --transport http wextl https://eu1.wextl.com/api/mcp --header "Authorization: Bearer wextl_..."

Add the same endpoint + bearer token to Cursor's MCP settings (mcp.json) as a remote server entry.

json
{
  "mcpServers": {
    "wextl": {
      "url": "https://eu1.wextl.com/api/mcp",
      "headers": { "Authorization": "Bearer wextl_..." }
    }
  }
}

Add WEXTL from ChatGPT's connector settings using the MCP endpoint. Like claude.ai, this drives the OAuth consent flow — no pasted token.

A key or OAuth grant is scoped to exactly one organization and one regional endpoint. If you work across multiple organizations, add one connection per organization — each shows up as a separate MCP server entry in your client.
