Monobank MCP-Server (Node.js/TypeScript)

Node.js/TypeScript-Implementierung des Monobank MCP-Servers, der ursprünglich in Python geschrieben wurde.

Der Monobank MCP-Server stellt Ihr persönliches Monobank-Konto (sowie öffentliche Wechselkurse) als Model Context Protocol (MCP)-Tools bereit.

Über diese Version

Dies ist eine Node.js/TypeScript-Portierung der ursprünglichen Python-Implementierung von @nklymok.

  • Originale Python-Version: https://github.com/nklymok/Monobank-MCP

  • Diese TypeScript-Version: Behält die gleichen Kern-Tools für persönliche Konten bei, bietet die Vorteile des Node.js/TypeScript-Ökosystems und enthält zusätzlich ein Tool für öffentliche Wechselkurse, das kein Token benötigt.

Funktionen

  • TypeScript/Node.js MCP-Server unter Verwendung des offiziellen @modelcontextprotocol/sdk

  • MCP-Tools:

    • get_client_info – Kundenidentität, Konten und Jars (erfordert MONOBANK_API_TOKEN).

    • get_statement – Kontoauszug für einen Zeitraum (erfordert Token). Validiert den Zeitraum vor dem API-Aufruf; Antworten verwenden Beträge in Haupteinheiten und ISO 8601 UTC-Zeiten für Transaktionen.

    • get_currency_rates – öffentliche Währungswechselkurse von Monobank (GET /bank/currency). Kein API-Token erforderlich.

Verwendung (veröffentlichtes Paket)

Der einfachste Weg, diesen MCP-Server zu nutzen, ist über das veröffentlichte npm-Paket:

  1. Registrieren Sie den Server in Ihrer MCP-Konfiguration

    {
      "mcpServers": {
        "monobank-mcp": {
          "command": "npx",
          "args": ["-y", "@alerix/monobank-mcp"],
          "env": {
            "MONOBANK_API_TOKEN": "your_token_here"
          }
        }
      }
    }

    Setzen Sie MONOBANK_API_TOKEN nur, wenn Sie get_client_info oder get_statement verwenden. get_currency_rates funktioniert auch ohne.

  2. Starten Sie Ihren MCP-Client – die Tools stehen entsprechend Ihrer Konfiguration zur Verfügung.

Entwicklung

Wenn Sie zur Entwicklung beitragen oder den Server modifizieren möchten:

  1. Klonen und Abhängigkeiten installieren

    git clone https://github.com/aler1x/monobank-mcp.git
    cd monobank-mcp
    npm install
  2. Starten Sie den Server nach der Installation (prepare führt npm run build aus). Für persönliche Tools setzen Sie MONOBANK_API_TOKEN.

    Windows (PowerShell):

    $env:MONOBANK_API_TOKEN="your_token_here"
    node dist/index.js

    Windows (Eingabeaufforderung):

    set MONOBANK_API_TOKEN=your_token_here
    node dist\index.js

    macOS/Linux:

    export MONOBANK_API_TOKEN=your_token_here
    node dist/index.js

    Oder in einer Zeile:

    MONOBANK_API_TOKEN=your_token_here node dist/index.js
  3. Entwicklung mit Hot-Reload (verwendet tsx --watch):

    MONOBANK_API_TOKEN=your_token_here npm run dev
  4. Build (TypeScript → dist/):

    npm run build

TDQS

A3.5/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions the authentication requirement (API token with permissions) which is valuable context, but doesn't describe what information is returned, whether there are rate limits, error conditions, or other behavioral traits. It adequately covers the basic operation but lacks detail about the tool's behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is appropriately concise with two sentences that each add value. The first sentence states the purpose, and the second adds important context about authentication requirements. There's no wasted text, though it could be slightly more structured.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given that this is a read operation with no parameters and no output schema, the description provides adequate but minimal information. It covers the purpose and authentication requirements, but doesn't describe what specific information is returned or the format of the response. For a tool that retrieves client information, more detail about the return data would be helpful.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has 0 parameters with 100% schema description coverage, so the schema already fully documents the parameter situation. The description doesn't need to add parameter information, and it appropriately doesn't discuss parameters. The baseline for 0 parameters with full schema coverage is 4.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: 'Get client information from Monobank API' with specific resources mentioned (client, accounts, jars). It distinguishes from the sibling tool 'get_statement' by focusing on client metadata rather than transaction data. However, it doesn't explicitly contrast with the sibling, so it's not a perfect 5.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides some usage context by mentioning the required API token and permissions, but doesn't explicitly state when to use this tool versus alternatives. It implies usage for retrieving client metadata but doesn't provide guidance about when not to use it or what the sibling tool 'get_statement' is for.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

get_statementA

Get account statement for a given period. Rate limit: 1 request per 60 seconds. Max period: 31 days + 1 hour. Rules: 1. Fetch from default account (account_id = '0') unless another account is specified. 2. Amounts are converted from the smallest currency unit (e.g., kopiyka, cent) to the main unit and returned as decimals. 3. Transaction timestamps ('time') are converted from Unix timestamps to ISO 8601 datetime strings (UTC). 4. Fields 'id', 'invoiceId', 'counterEdrpou', and 'counterIban' are omitted from the returned results.

NameRequiredDescriptionDefault
account_idYesAccount identifier from the list of accounts, or '0' for default
from_timestampYesStart of the statement period (Unix timestamp)
to_timestampYesEnd of the statement period (Unix timestamp)

TDQS

A4.2/5.0
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively describes rate limits ('1 request per 60 seconds'), constraints ('Max period: 31 days + 1 hour'), data transformation rules (currency conversion, timestamp formatting), and output filtering (omitted fields), providing comprehensive behavioral context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is efficiently structured with a clear purpose statement followed by rate limits, constraints, and specific rules in a numbered list format. Every sentence adds value without redundancy, making it easy to parse and understand.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a tool with no annotations and no output schema, the description does an excellent job covering behavioral aspects, constraints, and data transformations. However, it doesn't explicitly describe the return format or structure of the statement data, which would be helpful given the lack of output schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema description coverage is 100%, so the schema already documents all three parameters thoroughly. The description adds some context about default account behavior ('account_id = '0' unless another is specified') and timestamp usage, but doesn't provide significant additional parameter meaning beyond what the schema offers.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the specific action ('Get account statement') and resource ('for a given period'), distinguishing it from the sibling tool 'get_client_info' which presumably retrieves different information. It provides concrete details about what the tool does beyond just the name.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage by specifying a period requirement and default account behavior, but it doesn't explicitly state when to use this tool versus alternatives or provide any exclusion criteria. It offers some context but lacks explicit guidance on tool selection.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Disambiguation5/5

The two tools have clearly distinct purposes: get_client_info retrieves client metadata, accounts, and jars, while get_statement fetches transaction data for a specific period. There is no overlap or ambiguity between these functions.

Naming Consistency5/5

Both tools follow a consistent verb_noun naming pattern (get_client_info, get_statement) with identical verb style and snake_case formatting, making them predictable and easy to understand.

Tool Count2/5

With only two tools, the server feels severely under-scoped for a banking API. Key operations like creating transactions, managing accounts, or updating client details are missing, limiting its utility for comprehensive financial tasks.

Completeness2/5

The toolset is highly incomplete for a banking domain. It only supports read operations (get_client_info, get_statement) with no ability to perform writes (e.g., transfers, payments), updates, or deletions, leaving significant gaps in typical banking workflows.
