# mcp-ucash

<!-- mcp-name: io.github.UdotCASH/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:

```bash
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
```
