What you can do with this MCP connector

You're connecting your AI client directly to the Mambu Cloud Banking Platform using this server. It gives you operational access to core banking data—everything from client records and loan balances to transaction history and pending tasks.

To fetch specific client details, you call get_client, which retrieves a full record for one specified Mambu client. If you need basic identification info across multiple users, you can use list_clients to get a paginated list of all clients.

Retrieving account balances is straightforward. You'll check the current balance and status for a single deposit account using get_deposit_account. For loans, get_loan_account retrieves key data points from one specific loan account. When you need to manage client resources at scale, list_deposit_accounts lists all associated deposit accounts belonging to an entity, while list_loan_accounts shows multiple loan accounts and their outstanding balances for that entity.

For financial movements, you have two ways to go deep. You generate a detailed, paginated report of transactions within a given time frame by using list_transactions. Alternatively, if you just need a general view of what's happening across the board, you can use list_activities to get a list of overall banking events.

Auditing operational work items and communications is another major function. You check communication records via list_communications, which provides a full history of messages related to client accounts. If you need to track compliance actions or approvals, the server lets you list pending tasks with list_tasks or fetch details for one specific task using get_task.

This setup lets your agent build workflows that manage banking operations by calling these tools directly in a conversation. You can process data in batches by listing client resources; for example, running list_deposit_accounts against a group of clients lets you gather all necessary balance information before making a decision.

The server handles core financial record management through specialized tool calls. To get a comprehensive view of an entity's accounts, you can first run list_clients to identify the user, then call list_deposit_accounts and list_loan_accounts for that client ID. You'll use get_client if you need every detail on one person.

When tracking history or compliance, your agent uses dedicated tools. For instance, checking a full service interaction means calling list_communications. If the user needs to know what approvals are pending, they call list_tasks, which returns all open items requiring follow-up action in the system.

How Mambu MCP Works

  1. 1 Your AI client identifies the need (e.g., 'I need to know Acme Corp's total outstanding debt').
  2. 2 The MCP Server intercepts this request and maps it to the correct tool, calling get_client followed by list_loan_accounts.
  3. 3 Mambu returns the structured data payload, which your AI client reads and synthesizes into a human-readable report.

The bottom line is: Instead of writing complex API calls, you tell your agent what financial question you have, and it handles all the necessary tool execution.

Who Is Mambu MCP For?

This is for the Operations Engineer who needs to write automation that touches live banking data without building a full backend microservice. It's also for Compliance Officers tracking required actions, or Financial Analysts running ad-hoc reporting on client portfolios.

Financial Analyst

Runs daily reconciliation reports by calling list_transactions and cross-referencing balances with specific account lists.

Operations Engineer

Builds automated workflows that check for overdue items by using list_tasks and then fetching client details via get_client.

Compliance Officer

Audits client relationships by calling list_communications to track necessary disclosures or follow-ups.

What Changes When You Connect

  • Avoid jumping through five different dashboards. You can combine the results of get_client, list_loan_accounts, and list_deposit_accounts into one single, coherent response from your agent.
  • When compliance needs an audit trail, you don't just get a list; your agent calls list_communications to pull every message exchange related to the account opening.
  • Stop manual data pulls. Need to reconcile end-of-day figures? Use list_transactions to grab all movements and then use get_loan_account for the final balance check.
  • Managing multiple clients is simple. You can first run list_clients to get IDs, and then loop through those IDs calling get_task on each one to find pending reviews.
  • The server handles all the complexity of the Mambu v2 API calls behind the scenes. Your agent just asks for the data, and you get clean JSON output ready to use.

Real-World Use Cases

01

Client Onboarding Review

A new client file is flagged for review. The analyst tells their agent: 'Check Acme Corp.' The agent runs get_client to validate status, then calls list_loan_accounts and list_deposit_accounts to confirm all necessary accounts are active. Finally, it uses get_task to see if the required KYC review is pending.

02

Suspicious Activity Report

A client's account shows unusual activity. The compliance officer asks their agent to 'Investigate recent spending for Client 12345.' The agent executes list_transactions for the last 30 days, and then uses get_client to cross-reference the name against known high-risk profiles.

03

Loan Portfolio Health Check

The portfolio manager needs a snapshot of all loans. The agent first runs list_loan_accounts for every entity, then uses that list to call get_loan_account on each one individually to calculate the total outstanding principal across the entire book.

04

Audit Trail Generation

The team needs proof of all client interactions. They ask their agent to 'Get the full history for TechVentures.' The agent runs list_communications and combines that data with any pending tasks found by calling list_tasks, providing a complete audit record.

The Tradeoffs

Over-fetching all data at once

A developer tries to write one massive API call hoping it returns client details, loan balances, and transaction history simultaneously. This fails because the data is siloed across multiple Mambu endpoints.

Break it down into a sequence of calls. First, use get_client for identifying info; then, use list_loan_accounts to get all related loans; finally, call list_transactions using the client ID and date range.

Forgetting task context

The team gets a list of clients but forgets whether there are outstanding actions. They only check account balances, missing critical operational blockers.

Always run list_tasks after listing clients or accounts. This ensures you surface all necessary administrative follow-ups that might block a workflow.

Ignoring different account types

The system only queries deposit balances but misses the actual loan debt outstanding, leading to an inaccurate picture of client financial health.

Don't just check one type. Always run list_deposit_accounts AND list_loan_accounts when assessing a full client profile.

When It Fits, When It Doesn't

Use this Mambu MCP Server if your workflow requires access to live, transactional data from the core banking platform—specifically when you need to know who has what accounts, how much money they have right now, or what transactions happened yesterday. It's built for complex state management and auditing.

Don't use this if: 1) You only need static reference data (like a list of available product codes); those belong in a dedicated internal database lookup tool. 2) Your task is to write the accounting ledger itself; you can read it, but you don't create it here. If your process involves complex financial modeling or aggregation across multiple external systems (e.g., Mambu + payroll + CRM), use this as one data source within a larger agent framework, not as a standalone solution.

Works with Claude, ChatGPT, Cursor, and more

The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.

This server provides 11 capabilities that interface natively with Claude, ChatGPT, Cursor, and any MCP client. No middleware. No custom integration required.

Available Capabilities

get_client get_deposit_account get_loan_account get_task list_activities list_clients list_communications list_deposit_accounts list_loan_accounts list_tasks list_transactions

Manually checking client status is a multi-step headache.

Today, to get a full picture of a client's standing—their active accounts, their outstanding loans, and any pending tasks—you have to open the CRM dashboard, run one report for transactions, and then check three separate tabs just to find if they owe money or need an approval. It's clicking through six different screens and manually copying IDs.

With this MCP server, you ask your agent: 'What is the current status of Acme Corp?' The agent runs `get_client`, grabs details from `list_loan_accounts`, checks for pending work using `list_tasks`, and sends you one complete answer. It’s all in one prompt.

Mambu MCP Server: Get a full audit trail with list_communications.

Before, tracking down why two months ago the loan terms changed required searching through email archives, checking internal memos, and hoping someone saved an important chat record. There was no single source of truth for client discussions.

Now, your agent calls `list_communications` and pulls every message logged against that account ID—emails, notes, and system messages—putting the entire history directly into your workflow output. It's immediate, verifiable context.

Common Questions About Mambu MCP

How do I find out a client’s current total balance using get_client? +

You can’t get the full balance from just get_client. You must follow up by calling list_deposit_accounts and list_loan_accounts to aggregate all balances into one summary.

Can list_transactions handle multiple date ranges? +

The API handles filtering, so you specify the start and end dates in your prompt. It retrieves a paginated list of every transaction within that exact window.

Is get_task for client or account related tasks? +

get_task fetches general operational tasks assigned to users, such as required approvals or compliance reviews. These tasks apply to the internal process, not a specific client's balance.

How do I get all loan details for a client? +

You first use list_loan_accounts with the client ID to see all related loans. If you need deep details on one, call get_loan_account using that specific loan ID.

Does list_clients give me account balances? +

No, list_clients only provides basic identifying info (name, ID). To get any balance data, you must run a separate tool like list_deposit_accounts.

How does the Mambu MCP Server ensure data security when I use get_client? +

The server handles your tokens securely by encrypting them at rest. The credentials are injected into your AI client only at runtime, meaning they never sit in plain text within the system.

What happens if I try to use get_deposit_account with a non-existent account ID? +

The API returns an immediate error code (typically 404). Your agent needs to check the HTTP response status before expecting data, which is standard practice for reliable operations.

Does list_activities provide a unified view of all banking events? +

Yes, list_activities pulls together records from various system sources. This allows your agent to track everything—from deposits and transfers to internal tasks—in one place for auditing.

How do I find my Mambu API Key? +

Log in to your Mambu administration panel, go to Administration > Access > API Keys. There you can generate or copy your existing API key.

What is the subdomain? +

The subdomain is the first part of your Mambu URL. For example, if your URL is 'vinkius.mambu.com', your subdomain is 'vinkius'.

Is my data secure? +

Yes, your API key is encrypted at rest and injected securely at runtime for all operations.
