Available today. Use it from your connected AI after setup.

No other account needed.

Then ask your AI: use the uxc view door tool from mcp-ucash

Install mcp-ucash

The server’s own address, for the clients that take one directly. Or connect ahel once and every client you use reads it from one address, with the account kept on ahel rather than in each client’s config.

Claude Code
claude mcp add --transport http --scope user mcp-ucash 'https://mcp.u.cash/'
Run it once in your project, then open /mcp to approve any sign-in the server asks for.
Claude Desktop
https://mcp.u.cash/
Add a custom connector in Settings, paste this address, and approve the sign-in.
Cursor
cursor://anysphere.cursor-deeplink/mcp/install?name=mcp-ucash&config=eyJ1cmwiOiJodHRwczovL21jcC51LmNhc2gvIn0=
Open the link and Cursor adds the server at that address.
ChatGPT
https://mcp.u.cash/
In Settings, enable Developer mode, create an MCP app, and paste this address. Your plan and workspace must allow custom apps.
Codex
codex mcp add mcp-ucash --url 'https://mcp.u.cash/'
Run it once, then sign in with codex mcp login mcp-ucash if the server asks for an account.

From the project's README

As published by udotcash/mcp-ucash in README.md.

A merchant-side MCP server for U.CASH Pay. Let Claude Desktop, Cursor, or any MCP client manage a merchant's pay.u.cash: create checkouts, verify settlement webhooks, and read settings + integration credentials.

Tools

create_checkout(amount, currency, title, external_reference) → hosted checkout URL + transaction id
verify_webhook(raw_body, signature_header) → HMAC verify an X-Webhook-Signature
get_integrations() → Discord/Telegram/BigCommerce/Ecwid/Wix credentials (from /v1/integrations)
get_settings() → safe agent settings (from /v1/settings)

Run

# one-liner: uv installs an isolated Python 3.10+ and the deps for you
uvx --from mcp-ucash python -m mcp_ucash

Or from source:

pip install "mcp[cli]"
export UXC_API_KEY=uxc_...          # agent API key, for /v1/* reads
export UCASH_CLOUD_TOKEN=st_...     # store cloud token, for create_checkout
export UCASH_WEBHOOK_SECRET=...     # for verify_webhook
python mcp_ucash.py
