Connect from Claude.ai and Claude Desktop#

This guide connects the ZenCreator MCP server to Claude.ai (web) and Claude Desktop. Both use the same custom-connector flow: you add one URL and log in once in your browser. There are no API keys to paste and nothing to install — the ZenCreator MCP server is hosted and remote, secured with OAuth 2.1. Your Claude client stores the token and refreshes it automatically.

New here? Start with the Quickstart or the overview.

Prerequisite#

You need a ZenCreator account. Sign up or sign in at https://app.zencreator.pro — this is the account you'll log in with during the OAuth step below. Generation spends credits; top up at https://app.zencreator.pro/billing.

The MCP endpoint you'll connect to:

https://mcp.zncr.pro/mcp

Add the connector#

The flow is the same on Claude.ai and Claude Desktop:

  1. Open Settings → Connectors.
  2. Choose Add custom connector.
  3. Paste the URL https://mcp.zncr.pro/mcp.
  4. Save.

On first use, the client runs the OAuth login in your browser.

Older Claude Desktop builds used a config-file form instead of the Connectors UI; the server URL was the same value under mcpServers. If your build has the Connectors screen, prefer it.

Log in (OAuth)#

On first use, your client discovers the server's protected-resource metadata and opens your browser to log in at ZenCreator. You'll see a consent screen requesting two scopes:

  • mcp.read — read your profile, tasks, assets, templates, and prices.
  • mcp.generate — submit generations on your behalf.

Approve the consent screen. The client stores the resulting token and refreshes it automatically, so you only do this once. There are no API keys involved. (The server is an OAuth 2.1 Resource Server conforming to the MCP 2025-06-18 spec revision with audience-bound tokens.)

The globe icon is cosmetic#

On Claude.ai, custom-URL connectors show a generic globe icon rather than a brand logo. Brand icons are only shown for directory connectors. This is purely cosmetic and does not affect the connection.

Verify it works#

Once connected, ask your agent to check your account:

Run zencreator_get_me and tell me my credit balance.

A working connection returns your profile, including your credit balance and flags like nsfw_allowed, is_trusted, and out_of_credits. If it answers, you're connected and authenticated.

Troubleshooting#

  • Connector shows disconnected, or tools fail with an auth error: reconnect / re-authenticate. Open Settings → Connectors, and reconnect the ZenCreator connector to run the browser login again.
