Banks with MCP Servers | Agentic Banking Directory

Track banks implementing MCP servers for AI agent access to banking services.

The Model Context Protocol (MCP) is transforming how AI agents interact with financial services. Banks are now building MCP servers that allow AI assistants like Claude and ChatGPT to securely access banking data and services—enabling a new era of agentic banking, where AI doesn’t just respond but executes: authenticating users, retrieving context, initiating workflows, and completing tasks within defined compliance guardrails.

What is the Model Context Protocol (MCP)?

MCP is an open-source standard developed by Anthropic (released November 2024) that standardizes how large language models (LLMs) interact with external tools and data sources. It uses JSON-RPC 2.0 as its communication protocol, defining "servers" that host data and resources, and "clients" (like Claude or ChatGPT) that connect with controlled access.

For banking, MCP enables AI agents to access dynamic financial data—account balances, transactions, payment capabilities—rather than relying solely on static or pre-loaded information. This opens up possibilities for AI-powered financial management, automated payments, and intelligent financial insights that were previously impossible.

AI in banking: selected stories

Beyond MCP servers, banks and vendors are deploying AI assistants, agentic platforms, and natural-language API agents. A few examples:

Agentic payments (card rails)

Visa Agentic Ready (March 2026) — Visa launched a program so banks can test payments made by AI agents on behalf of consumers in production-grade environments. Initially in Europe with 21 issuing partners including Barclays, HSBC UK, Banco Santander, Revolut, Commerzbank, Nationwide, Nexi, Raiffeisen Bank International, and DZ Bank. The program uses existing tools: tokenization (so the agent uses a digital token, not the real card number), biometric authentication to link the token to the account holder, risk scoring, and configurable spending controls. Banco Santander completed an end-to-end test—an AI agent bought a book from a merchant using a Visa credential issued in Spain—with full authorization, tokenized payment, and settlement and no manual input from the consumer. Visa plans to expand to other regions.

Agentic lending

Finastra agentic AI for mortgage (March 2026) — Finastra is launching an agentic AI tool for mortgage lenders, to be added to its loan origination system Mortgagebot by year-end. The tool assists originators across the application lifecycle—document processing, customer engagement—and uses agentic AI to help identify abnormalities that need attention. Finastra is using Microsoft Azure for the AI capabilities. Andrew Bateman, EVP for lending at Finastra, described the move as part of efforts to increase accuracy and efficiency in originations.

API for AI agents

Brighty agentic banking API (March 2026) — Brighty, a Poland-based fintech bridging digital finance and traditional banking, launched an API that lets AI agents perform banking tasks: check balances across accounts, send payments, convert currencies in real time, manage payroll, and reconcile transactions. Its AI agent can read incoming invoices and initiate international transfers (with full audit trails and compliance) over SEPA and SWIFT, and request payment approvals from accountholders. The platform supports configurable account settings, access controls, and security rules via the API, plus issuance of physical and virtual Visa-branded debit cards for fiat and crypto (e.g. bitcoin, Ether, USDC, EURC). Target users include freelancers, digital nomads, crypto enthusiasts, and startups. Co-founder and CTO Nick Denisenko: “With this API, we're extending [transparent, programmable infrastructure] to the age of intelligent agents — giving businesses a way to automate financial operations that would otherwise require a team of accountants.”

Open Banking + AI

bunq and Mastercard (2024) — bunq became the first bank in Europe to leverage AI in open banking with Mastercard. Its generative AI assistant Finn uses transaction data across linked accounts to answer natural-language questions (e.g. spending on coffee or restaurants). Launched in the Netherlands, France, and Germany; nearly 40% of surveyed users reported a significant increase in app usage within two weeks.

Agentic AI platform

Kasisto KAIgentic (2025) — Kasisto launched KAIgentic as an agentic AI platform purpose-built for banking, with compliance-by-design, hallucination detection, and audit logging. It orchestrates customer experience, compliance, knowledge, and operations agents; supports multiple LLMs including Kasisto's domain-tuned KaiGPT; and integrates with Microsoft Agent 365. In early access with select banks and credit unions across North America, Europe, and Asia.

Elastic MCP Server for Digital Banking

by amir-gorji

Digital banking tribes sit on massive telemetry: payment rails (SWIFT gpi, SEPA), customer session data, APM traces, and microservice logs. Querying this data today requires mastering Elasticsearch DSL or relying on pre-built dashboards that may not answer ad-hoc questions. This stdio MCP server for Elasticsearch (with multi-stage PII redaction) gives Business Managers, Architects, and Developers conversational access to that operational data—without writing KQL or Elasticsearch DSL. Suitable for financial institutions or regulated environments.

The Rise of Agentic Banking

We are witnessing the early days of a massive technological platform shift. As AI capabilities advance, people are delegating more tasks to AI agents—and financial services are no exception. The question is no longer whether AI will interact with banking systems, but how it will do so safely and effectively. As Financial IT notes, agentic banking is where AI doesn’t just respond—it executes: autonomous agents can authenticate users, retrieve context, initiate workflows, orchestrate decisions across systems, and complete tasks within defined compliance guardrails. A major trust gap still holds many organisations back from scaling agentic AI beyond pilots—which is why governance, transparent decisioning, and the banker remaining steward of the client relationship are seen as the real differentiators.

Why MCP Matters for Banking

Traditional approaches to AI-banking integration involved giving AI access to passwords or having it scrape websites—approaches that are insecure and often violate terms of service. MCP provides a standardized, secure protocol for AI agents to access banking services with proper authentication, authorization, and audit trails.

  • Standardization — MCP is an open protocol, reducing integration friction across different AI models and banking platforms
  • Security — Proper authentication, granular permissions, and revocable access replace insecure workarounds
  • Interoperability — Same MCP server can work with Claude, ChatGPT, and other compatible AI models
  • Auditability — All AI interactions can be logged and monitored for compliance

Griffin: The Agentic Bank

Griffin, a UK-based Banking-as-a-Service platform regulated by the PRA and FCA (FRN 970920), is pioneering full read-write MCP capabilities. Their MCP server enables AI agents to:

  • Open bank accounts programmatically
  • Initiate payments and transfers
  • Analyze transaction history and patterns
  • Build complete fintech application prototypes

Currently in beta with sandbox access, Griffin is actively working with customers who want to deploy agentic banking capabilities in production settings.

Grasshopper Bank: First US Bank with MCP

Grasshopper Bank, partnering with digital banking technology provider Narmi, launched the first MCP server by a US bank in August 2025. Their implementation focuses on read-only access for business banking clients, enabling:

  • Natural language queries for account balances and transaction data
  • AI-powered expense categorization and vendor analysis
  • Cash flow forecasting and predictive insights
  • Budget guidance for small businesses and startups

The read-only constraint is intentional—it provides valuable insights without the risk of AI initiating unintended transactions. General availability is expected in Q4 2025.

Coinbase Payments MCP: On-Chain Payments for AI

Coinbase launched Payments MCP in September 2025, enabling AI agents to conduct autonomous on-chain financial transactions using stablecoins. Unlike traditional banking MCP implementations focused on account access, Coinbase's approach enables agents to actually spend money autonomously.

  • Embedded wallet creation with email/OTP authentication
  • USDC onramp integration for wallet funding
  • Stablecoin payments via the x402 protocol
  • Compatible with Claude Desktop, Gemini, and other LLMs

The x402 protocol leverages HTTP's "402 Payment Required" status code to enable instant stablecoin payments directly over HTTP. This allows APIs, apps, and agents to transact seamlessly without subscriptions or manual checkout processes. Install via npx @coinbase/payments-mcp.

The Future of Agentic Banking

Success depends as much on institutional readiness as on technology. The infrastructure gap between current banking systems and the requirements of agentic finance is substantial, and it won’t close overnight—so adoption will unfold over 2026 and beyond as more institutions modernize and deploy governed, auditable agentic workflows.

As MCP adoption grows, we can expect:

  • More banks launching MCP servers — Both established banks and neobanks
  • Expanded capabilities — From read-only to read-write in more jurisdictions
  • Regulatory frameworks — Specific guidance for AI access to banking services
  • New fintech applications — Built natively on agentic banking capabilities
  • Integration with Open Banking — MCP complementing existing Open Banking APIs
