Five tools, one connection

Install once. Your IDE gets accurate SDK docs, API schemas, and production-ready code templates — grounded in the current SDK.

Tool What it does Returns
browse APIs icon Browse APIs

List every available endpoint with HTTP methods, SDK version details, and MLE encryption support per endpoint.

 API index
API details icon Get API details

Pull complete docs for any API class — method signatures, parameters, return types, and usage examples across SDK versions.

 Method + params
model lookup icon Look up models

Retrieve request and response model schemas — property names, data types, and required versus optional fields for any model class.

 Schema + types
setup guide icon SDK setup guide

Get the complete SDK configuration guide for any language — installation, authentication setup, MLE encryption configuration, and best practices.

 Setup guide
generate code icon Generate code

Get production-ready code templates for any endpoint in Java, Python, Node.js, PHP, and Ruby — with authentication wired in and ready to run.

 Runnable code

Built for how developers actually work

Real questions get real answers from the API specs.

CHECKOUT

"How do I integrate Unified Checkout for my retail merchants?"

Gets a step-by-step integration guide with code samples in your preferred language, sourced from the Unified Checkout implementation guide.

AGENTIC WORKFLOWS

"What APIs do I need for recurring billing?"

Returns a grounded answer from the wiki listing the specific API endpoints, required parameters, and token flow — with source page citations.                                                                                                             

DEBUGGING

"I'm getting PROCESSOR_DECLINED reason code 05 — what does that mean?"

Gets the specific meaning of reason code 05, the recommended remediation steps for that decline type, and retry logic guidance from the error handling docs.

Get started in 3 steps

No install. No CLI. Just add your credentials and a single config block.

WHY IT MATTERS

Grounded answers, not hallucinations

The Developer MCP reads directly from the Visa Acceptance knowledge base — not from model training data. Every answer cites the source page. No guessing, because the agent is reading the docs.

document icon

Source-cited answers

Every response links to the specific wiki page it was drawn from, so you can verify and read further.
clock icon

Always current

The knowledge base syncs nightly. API changes, new fields, and deprecations are reflected without a model retrain.
connections icon

Works in any MCP-compatible IDE

Claude Code, Cursor, VS Code with Copilot, Windsurf — one config block, any editor.

WITHOUT MCP

"To process a payment with Visa, you'll typically need to use their payment API. The exact endpoint varies, but something like /v1/payments should work..."

Model generates a plausible sounding but potentially incorrect answer from training data.

WITH DEVELOPER MCP

"Based on the Payments API guide, the endpoint is POST /pts/v2/payments. The required fields are clientReferenceInformation, orderInformation.amountDetails, and paymentInformation.card..."

Answer sourced from: Payments API Reference — page last updated June 2026.
