mcp-ucash

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

bash

# 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:

Terminal

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
