What is the Modulr MCP Server?
The Modulr MCP Server wraps incredibly defensive digital signatures (HMAC SHA-256) autonomously underneath a native Language Model Chat interface. Meaning, your AI has programmatic limits to fire secure European and British payment rails on command natively.
Core Functionality
- Create Modulr Customers/Accounts — Manage deeply nested multi-layered B2B structures. Automatically provision Sort-Code ledgers via
modulr_create_account. - Payment Initiation — Run automated payroll or contractor compensation logic utilizing direct clearing paths mapping via
modulr_create_payment. - Algorithmic Tracing — Check real-time payment states checking failures or settlements organically utilizing
modulr_list_payments.
How it works
- From your Modulr Finance administrative interface, spawn your API Key Profile and the underlying API Secret Hash.
- Vinkius natively utilizes the
MODULR_API_SECRETnot as a password, but natively applying a Cryptographic Hash generating Nonces and Date Timestamps implicitly on every Chat-driven Tool call to authenticate accurately with European servers.
Use Cases
- Lending Startups — Direct integration validating funds exactly when needed.
- Payment Reconciliations — Have the Agent review your physical transactional ledger.

Frequently asked questions
Modulr requires complex timestamped HMAC API Signatures, how does the prompt handle that?
We handle that completely in the background Engine! The Vinkius runtime grabs your static API Secret from configurations once. Then, every time the Language Model triggers a payment, our Node.js runtime creates random cryptographic hex Nonces, aligns current UTC Date limits, hashes the combination uniquely via SHA-256 and packs it into the underlying header dynamically natively.
Can the Agent generate new SEPA/UK Accounts?
Yes, using modulr_create_account, you can spawn multiple isolated UK GBP ledgers natively linked to customers.
Are cross-border Faster Payments supported natively?
Absolutely. You can inject external sorts codes inside the modulr_create_payment orchestrations delivering funds transparently via clearing houses.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Modulr MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
