Comprehensive Python client and Model Context Protocol server for Robokassa — the Russian payment gateway.

Covers the full API surface: checkout, XML status interfaces, refunds, holding (pre-auth), recurring subscriptions, 54-ФЗ fiscal receipts, Partner API, and auxiliary endpoints.

Install (once published)

# As an MCP server for Claude Desktop / Claude Code / Cursor / Windsurf
uvx robokassa-mcp

# As a Python library
pip install robokassa-mcp

Use as a Python library

import asyncio
from decimal import Decimal
from robokassa import create_invoice, RobokassaClient

# Build a signed checkout URL (no HTTP — just URL construction).
invoice = create_invoice(
    merchant_login="my-shop",
    out_sum=Decimal("599.00"),
    inv_id=12345,
    password1="...",
    description="Premium subscription",
    email="[email protected]",
)
print(invoice.url)  # https://auth.robokassa.ru/Merchant/Index.aspx?...

# Check the state of a payment (hits the OpStateExt XML endpoint).
async def check() -> None:
    async with RobokassaClient("my-shop", password2="...") as client:
        state = await client.check_payment(inv_id=12345)
        print(state.is_paid, state.info.op_key)

asyncio.run(check())

Full refund flow

from robokassa import RobokassaClient

async def refund_flow(inv_id: int) -> None:
    async with RobokassaClient("my-shop", password2="p2", password3="p3") as client:
        # 1. Fetch the payment state to get its OpKey.
        state = await client.check_payment(inv_id)
        assert state.info.op_key, "payment not complete yet"

        # 2. Initiate a refund.
        created = await client.refund_create(state.info.op_key)
        print("refund requestId:", created.request_id)

        # 3. Poll status until finished / canceled.
        while True:
            status = await client.refund_status(created.request_id)
            if status.is_terminal:
                print("final:", status.state)
                break

Webhook signature verification (FastAPI example)

from fastapi import FastAPI, Request, HTTPException, PlainTextResponse
from robokassa import verify_result_signature, build_ok_response

app = FastAPI()

@app.post("/robokassa/result")
async def result_url(req: Request) -> PlainTextResponse:
    form = dict(await req.form())
    if not verify_result_signature(form, password2="..."):
        raise HTTPException(status_code=403, detail="Bad signature")
    # ... persist the notification, mark invoice paid ...
    return PlainTextResponse(build_ok_response(form["InvId"]))

MCP tools exposed to agents

All 18 tools are wrapped as @mcp.tool() and available to any MCP-capable agent (Claude Desktop, Claude Code, Cursor, Windsurf, etc.).

Tool	Purpose	Auth
create_invoice	Build a signed checkout URL (optional 54-ФЗ receipt).	Password#1
check_payment	Get current state of a payment by InvId (via OpStateExt).	Password#2
list_currencies	List payment methods available to the shop.	—
calc_out_sum	Compute amount credited to shop for a given payment.	Password#1
refund_create	Initiate a refund (requires Refund API access).	Password#3 JWT
refund_status	Poll refund progress by requestId.	—
verify_result_signature	Validate a ResultURL webhook.	Password#2
verify_success_signature	Validate a SuccessURL redirect.	Password#1
hold_init / hold_confirm / hold_cancel	Two-step card pre-authorization.	Password#1
init_recurring_parent / recurring_charge	Subscription auto-charges.	Password#1
build_split_invoice	Marketplace multi-recipient checkout.	—
send_sms	Paid SMS service.	Password#1
second_receipt_create / second_receipt_status	54-ФЗ final receipt after advance.	Password#1
partner_refund	Alternative refund path for partner integrators.	Partner JWT

Low-level signature helpers are available from Python only: compute_signature, op_state_signature, build_checkout_signature, build_refund_jwt, build_sms_signature, compute_result_signature, compute_success_signature, encode_fiscal_body.

API coverage

Mapped against the 8 public Robokassa API groups:

Group	Coverage	Module
Merchant Checkout	✅ create_invoice (+ 54-ФЗ)	robokassa.checkout
XML Interfaces	✅ check_payment, list_currencies, calc_out_sum	robokassa.xml_interface
Refund API	✅ refund_create, refund_status	robokassa.refund
Holding / Pre-auth	✅ init / confirm / cancel	robokassa.holding
Recurring	✅ parent + child	robokassa.recurring
Fiscal 54-ФЗ	✅ second receipt create / status	robokassa.fiscal
Partner API	🟡 partner_refund only — see coverage notes	robokassa.partner
Auxiliary	✅ send_sms, webhook signatures, split payments	robokassa.sms, robokassa.webhooks, robokassa.split

Environment variables

Most high-level entry points fall back to these env vars when credentials aren't passed explicitly:

Variable	Required for
ROBOKASSA_LOGIN	All operations
ROBOKASSA_PASSWORD1	Checkout, webhook SuccessURL verification, CalcOutSumm, fiscal, SMS
ROBOKASSA_PASSWORD2	check_payment (OpStateExt), webhook ResultURL verification
ROBOKASSA_PASSWORD3	refund_create

Signature algorithms

All signature-producing helpers accept algorithm= with "md5" / "sha256" / "sha384" / "sha512" — match whatever is configured in your Robokassa cabinet.
