About ClearBank MCP Server
The ClearBank MCP Server wraps incredibly defensive digital signatures (RSA-SHA256 PEM) 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.
Mastra's agent abstraction provides a clean separation between LLM logic and ClearBank tool infrastructure. Connect 8 tools through the Vinkius and use Mastra's built-in workflow engine to chain tool calls with conditional logic, retries, and parallel execution — deployable to any Node.js host in one command.
Core Functionality
- Virtual Account Provisioning — Manage deeply nested multi-layered B2B structures. Automatically provision Sort-Code ledgers via
clearbank_create_account. - Payment Initiation (FPS & CHAPS) — Run automated payroll or contractor compensation using direct clearing paths via
clearbank_create_faster_payment. - Algorithmic Tracing — Check real-time payment states organically utilizing
clearbank_get_payment_status.
Use Cases
- Baas Platforms — Direct integration validating funds exactly when needed under FPS limits.
- Treasury Automation — Have the Agent review your high-volume clearing state.
The ClearBank MCP Server exposes 8 tools through the Vinkius. Connect it to Mastra AI in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
