Claude.ai (the web app, separate from Claude Desktop) supports MCP via Custom Connectors. Adding one requires a paid plan and a remote MCP URL. Important: Claude.ai web only accepts HTTPS remote MCP endpoints, not local stdio. The Kataven MCP server runs locally over stdio, so you need a tunnel — follow the tunnel recipe before continuing here. If you’re using Claude Desktop (the local app), it speaks stdio directly — see Claude Desktop setup. No tunnel needed.Documentation Index

Plan required: Claude Pro / Max / Team / Enterprise. Free Claude can use directory connectors (Gmail, Slack, etc.) but not custom MCP connectors.
1. Run the tunnel
Follow Tunneling end-to-end. You should end up with a public HTTPS URL likehttps://abc123.ngrok.app/sse.
2. Add the custom connector
- Open claude.ai/settings/connectors (or Claude.ai → your profile → Settings → Connectors).
- Scroll to the bottom of the Connectors page → Add custom connector.
- Fill in:
- Name:
Kataven - MCP Server URL: the public HTTPS URL from step 1 (e.g.
https://abc123.ngrok.app/sse).
- Name:
- Save.
3. Use it
Start a new chat (no restart needed). Ask:List all my Kataven agents.Claude calls
kataven_list_agents through the connector. You’ll see a tools-used summary in Claude’s response.
4. Verify in the dashboard
| What changed | Open in Hub UI |
|---|---|
| Agents | hub.kataven.ai/agents |
| Phone numbers | hub.kataven.ai/phone-numbers |
| Live or recent calls | hub.kataven.ai/conversations |
| Campaigns | hub.kataven.ai/campaigns |
Operational notes
- Free ngrok URLs change between sessions and idle out. Pin a paid ngrok subdomain or use Cloudflare Tunnel — see Tunneling § Stable URLs.
- Custom connectors don’t sync across plan upgrades. If you downgrade from Pro to Free temporarily, custom connectors get hidden until you re-upgrade.
