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.

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.

Cursor's Agent mode turns Modulr into an in-editor superpower. Ask Cursor to generate code using live data from Modulr and it fetches, processes, and writes — all in a single agentic loop. 7 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.

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 Cursor in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Why Use Cursor with the Modulr MCP Server

Cursor AI Code Editor provides unique advantages when paired with Modulr through the Model Context Protocol.

Agent mode turns Cursor into an autonomous coding assistant that can read files, run commands, and call MCP tools without switching context

Cursor's Composer feature can generate entire files using real-time data fetched through MCP — no copy-pasting from external dashboards

MCP tools appear alongside built-in tools like file reading and terminal access, creating a unified agentic environment

VS Code extension compatibility means your existing workflow, keybindings, and extensions all work alongside MCP tools

Modulr + Cursor Use Cases

Practical scenarios where Cursor combined with the Modulr MCP Server delivers measurable value.

Code generation with live data: ask Cursor to generate a security report module using live DNS and subdomain data fetched through MCP

Automated documentation: have Cursor query your API's tool schemas and generate TypeScript interfaces or OpenAPI specs automatically

Infrastructure-as-code: Cursor can fetch domain configurations and generate corresponding Terraform or CloudFormation templates

Test scaffolding: ask Cursor to pull real API responses via MCP and generate unit test fixtures from actual data

Modulr + Cursor FAQ

Common questions about integrating Modulr MCP Server with Cursor.

What is Agent mode and why does it matter for MCP?

Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.

Where does Cursor store MCP configuration?

Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.

Can Cursor use MCP tools in inline edits?

No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design — tool calls require user visibility and approval.

How do I verify MCP tools are loaded?

Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
