Tochka Bank Mcp

@theyahia/tochka-bank-mcp

MCP server for the real Tochka Bank business API (https://enter.tochka.com/uapi). It lets an MCP client (Claude Desktop, Cursor, etc.) read your business accounts, balances and statements, look up your company details, and prepare outgoing ruble payments for you to sign.

> ⚠️ This server can prepare real payments. create_payment builds a payment > via Tochka's for-sign flow: it never sends money on its own — a human signs > each payment in Tochka internet-bank (SMS). It also requires confirm: true > (otherwise it returns a dry-run preview) and respects an amount limit. Run the > server without auto-approve for tools and keep TOCHKA_MAX_PAYMENT_RUB set > to a sane value.

Features

• Accounts, balances, and (asynchronous) statements
• Company/customer info
• Outgoing payments via the for-sign flow, with dry-run preview, a required

confirm flag, an amount limit, and an optional recipient allowlist

• OAuth 2.0 hybrid auth with a one-time auth command and automatic token refresh
• PII/secret redaction, request timeouts, rate-limit handling, structured output

Install

npx -y @theyahia/tochka-bank-mcp

Requires Node.js ≥ 18.

Authentication

Tochka's account and payment APIs require the OAuth 2.0 hybrid flow — a bare client_credentials token is not enough. Setup is a one-time step:

1. In Tochka internet-bank, open Интеграции и API, create an application, and

copy its client id and client secret.

1. Register a redirect URI for the app. For local setup use

http://localhost:8765/callback (or set TOCHKA_REDIRECT_URI to match what you registered — the host must be a loopback address).

1. Run the one-time authorization (opens your browser, you approve the requested

permissions, tokens are saved locally):

``bash TOCHKA_CLIENT_ID=... TOCHKA_CLIENT_SECRET=... npx -y @theyahia/tochka-bank-mcp auth ``

Run npx -y @theyahia/tochka-bank-mcp auth --help for details.

After that, the server refreshes tokens automatically (access token ~24h, refresh token ~30d). For headless deployments you can instead provide the refresh token via TOCHKA_REFRESH_TOKEN.

> Single-tenant alternative: Tochka also supports a JWT generated directly in the > developer cabinet. This server currently implements the OAuth flow; JWT support > can be added by setting TOCHKA_REFRESH_TOKEN-style config in a future release.

Configuration

| Variable | Required | Description | |----------|----------|-------------| | TOCHKA_CLIENT_ID | Yes | OAuth client id from the Tochka developer cabinet | | TOCHKA_CLIENT_SECRET | Yes | OAuth client secret | | TOCHKA_REDIRECT_URI | No | OAuth redirect URI (default http://localhost:8765/callback); must match the one registered for your app | | TOCHKA_BASE_URL | No | API base (default https://enter.tochka.com/uapi; sandbox https://enter.tochka.com/sandbox/v2) | | TOCHKA_TOKEN_STORE | No | Token file path (default ~/.config/tochka-bank-mcp/tokens.json, mode 0600) | | TOCHKA_REFRESH_TOKEN | No | Pre-issued refresh token (headless; skips the auth step) | | TOCHKA_MAX_PAYMENT_RUB | No | Max payment amount allowed by create_payment (default 100000) | | TOCHKA_ALLOWED_RECIPIENTS | No | Comma-separated recipient account allowlist for create_payment | | TOCHKA_STATEMENT_TIMEOUT_MS | No | Max wait for an async statement to become Ready (default 25000) |

Claude Desktop setup

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "tochka-bank": {
      "command": "npx",
      "args": ["-y", "@theyahia/tochka-bank-mcp"],
      "env": {
        "TOCHKA_CLIENT_ID": "your-client-id",
        "TOCHKA_CLIENT_SECRET": "your-client-secret"
      }
    }
  }
}

Run the auth step (above) once before starting the client so the tokens exist.

Tools

| Tool | Kind | Description | |------|------|-------------| | list_accounts | read | List business accounts (accountId, currency, type, status) | | get_account_balance | read | Balances for an account (one row per balance type) | | get_statement | read | Transactions for a date range (async: init + poll) | | list_customers | read | Your Tochka customer codes (legal entities) | | get_company_info | read | Company details for a customer code (auto-selected if only one) | | create_payment | write / destructive | Prepare an outgoing RUB payment for signing (rubles, dry-run unless confirm:true) | | get_payment_status | read | Payment status by request_id |

External counterparties are not a Tochka resource; derive them from get_statement transactions.

Demo prompts

1. "Show me all my Tochka Bank accounts and their balances."
2. "Prepare a payment of 75000.50 RUB to OOO Romashka, account 40702810000000005678,

BIK 044525225, for web development services — show me a preview first."

1. "Get my company registration info from Tochka Bank."

Security

• create_payment is annotated destructiveHint, requires confirm: true,

supports dry_run, enforces TOCHKA_MAX_PAYMENT_RUB, and an optional recipient allowlist. Funds never move without a human signing in internet-bank.

• API error bodies can contain INNs, account numbers, and balances; all error

messages and logs are redacted (identifiers keep only the last 4 characters).

• Tokens are stored locally (mode 0600). Do not commit the token store.
