A²D - Agentic Asset Designer - Design secure, compliant MCP Server specifications and Agent Cards with built-in mocking, validation, and seamless publishing to Anypoint Exchange
MCP Design, Mock & Test — design, mock, and test MCP servers and Agent Cards.
Design-First Approach for Agentic Assets
Empower AI Engineers and Integration / API Developers through no-code design tools with built-in security, testing, and compliance checking to ensure quality and consistency across your organization.
Overview
Dashboard & Analytics
Get an at-a-glance view of your MCP Servers and Agent Cards. Summary metrics cover total assets, publishing (A²L, Exchange), mocking services and scenarios, and testing (tests, runs, passed/failed). Expandable Summary, Assets, and Testing sections show runs per day, pass/fail/skip distribution, and results by MCP Servers and Agent Cards.
A²D Features
The A²D Features enables organization to build future-proof agentic assets to accelerate reliable and high quality implementation in the landscape transformation. Democratize agentic asset design to every user and drive innovations faster by shifting left in the asset delivery.
- • Import from HTTP-Streamable endpoints
- • Convert OpenAPI specs to MCP
- • Design MCP Servers from scratch
- • Download specifications as JSON
- • Create new by uploading JSON specs

AI-Native Workflow
Drive A²D straight from your AI coding agent. The Platform MCP exposes every design, mock, test, and publish action as MCP tools, and A²D Skills teach your agent the conventions to shape assets correctly — so you can go from prompt to published agentic asset without leaving your editor.
- • One MCP endpoint, scoped to your organization with a Platform API key
- • Design MCP Servers, Agent Cards & REST APIs — then mock, test, and publish
- • Every A²D authoring primitive available as an MCP tool
- • Covers lifecycle, mock scenarios, security, testing & publishing
- • Self-served from a public, versioned skills manifest
- • Works with any MCP-capable AI agent

Frequently Asked Questions
MCP mocking, API mocking, agent mocking, and the design-first approach — explained.
MCP mocking is the practice of standing up a realistic mock of a Model Context Protocol (MCP) server — its tools, resources, and prompts — so agents and clients can be built and tested before the real server exists. A²D lets you design an MCP server spec and instantly serve a secure mocking endpoint with configurable scenarios per tool.
API mocking in A²D means designing a REST API or MCP server spec first, then serving live mock responses from that spec. Because the mock is generated from the design, it stays in sync with the contract and supports multiple scenarios, authentication types, and environments (Mock, Pre-prod, Prod).
Yes. A²D lets you design A2A agent cards with reusable skills and mock their behavior end to end. You can invoke tools, resources, and prompts against mock scenarios in the built-in playground, and run automated test suites against agent cards across environments.
Design-first means you define the MCP server or agent card specification up front — before any implementation — and validate it against organization design rules. A²D turns that design into a runnable mock and test harness, so teams shift quality left and agree on the contract before writing backend code.
No. A²D is not a commercial product and will remain free forever for MCP, Agents and REST API Design-First implementations.
