About 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.
The Vercel AI SDK gives every Modulr tool full TypeScript type inference, IDE autocomplete, and compile-time error checking. Connect 7 tools through Vinkius and stream results progressively to React, Svelte, or Vue components. works on Edge Functions, Cloudflare Workers, and any Node.js runtime.
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.
Use Cases
- Lending Startups — Direct integration validating funds exactly when needed.
- Payment Reconciliations — Have the Agent review your physical transactional ledger.
The Modulr MCP Server exposes 7 tools through the Vinkius. Connect it to Vercel AI SDK in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
