Prism in one click.
Prism is an openapi spec mock and validation proxy you can run on your own machine. Launch it in Even Stacks in one click, serve it over trusted HTTPS, and let your AI agents operate it.
What is Prism?
Prism is an open-source HTTP mock server and validation proxy driven by OpenAPI specifications. It generates realistic mock responses from API descriptions and validates live request and response payloads.
Run Prism in Even
Even Stacks launches Prism as a managed container on your own machine. No compose files, no manual setup.
- Open the Even Stacks panel in Even. The container engine starts on demand.
- Find Prism in the one-click services and click Launch.
- Even pulls the image, starts it on port 4010, and serves it over trusted HTTPS at
https://prism.localhost.
Drive Prism with your AI agents
Even ships an MCP, so any agent you run inside Even (Claude Code, Codex, and more) can operate Prism directly, at both the UI level and the container level.
Through the Even MCP an agent can run commands inside the container, build against the service, and read its logs to debug. It runs commands inside the container, reads its logs, and for web apps opens and clicks through the interface in Even's own browser pane. Ask once, for example "set up Prism and get it ready", and the agent handles it end to end.
