WireMock for MCP development

Build MCP Services Faster With API Simulation

Everyone is racing to get AI-native experiences, agents and Model Context Protocol (MCP) servers out the door – and MCP depends on APIs.

WireMock Cloud simulates production APIs, giving you production-realistic behavior that you can use when building MCP services and AI agents to iterate faster without dependency on flakey, inaccessible, expensive or not-yet-built APIs.

API Simulation Matters More Than Ever When Building MCP Services.
‍

MCP Services and AI agents rely on non-deterministic feedback from APIs…

...but those APIs may not even be built yet, or they may be difficult to access early on in development.

Simulate the API dependencies your MCP integration depends on. Decouple your MCP functionality from dependencies, and get the feedback you need to iterate quickly.

Real-world behavior will impact your agents… catch it early.

WireMock Cloud lets you simulate delays, faults and other forms of chaos that will impact the experience your customers have with your cutting-edge AI features.

Catch unexpected behaviors early to guarantee you ship the best feature possible for your users.

Using simulated APIs lets you iterate your API designs rapidly

Design your APIs based on the actual development feedback of building your MCP services.

By using simulated APIs, you can iterate rapidly and ultimately produce the API spec to build that you know is exactly what you need.

Testing the interactions between APIs and agents is a brand new challenge.

As your AI features develop, you’ll find it’s increasingly difficult to properly test under the weight of API dependencies.

Abstracting those dependencies with API simulation is the answer.
