Api Mock Server
Stand up mock API behavior from your agent so frontend and integrations can progress before the real backend exists.
Overview
api-mock-server is a MCP server for the Validate phase that exposes mock API endpoints and controls to your agent via Cloudflare Workers.
What is this MCP server?
- Remote MCP mock-server on Cloudflare Workers (streamable HTTP)
- Lets agents configure or drive mock API scenarios during build spikes
- Avoids local mock stack setup for quick indie experiments
- Version 1.0.0; source in api-mock-server-api repository
- Works alongside api-flow-analyzer and api-payload-auditor in Lazy Mac family
- Published as MCP server version 1.0.0
- Remote endpoint: api.lazy-mac.com/api-mock-server/mcp (streamable-http)
- GitHub: lazymac2x/api-mock-server-api
What problem does it solve?
Your UI or agent integration is blocked because the backend API does not exist yet and local mock setup eats a day.
Who is it for?
Indie devs prototyping SaaS or agent features who need quick HTTP mocks without maintaining a separate mock container.
Skip if: Enterprises requiring durable mock fleets, strict OpenAPI sync, or air-gapped MCP with no public remote URL.
What do I get? / Deliverables
You connect remote MCP mock tools so development and demos proceed against stand-in APIs while contracts stabilize.
- Callable mock API behavior reachable from agent-driven workflows
- Unblocked frontend or agent clients during API design lag
- Shorter prototype cycles before swapping to real backends

How it compares
Remote MCP mock API host, not Postman collections alone or a production API gateway.
Common Questions / FAQ
Who is api-mock-server for?
Builders using MCP agents who need temporary API responses for prototypes, demos, or parallel frontend work.
When should I use api-mock-server?
Use it during validate/prototype (and early build) when the real API is unfinished but clients or agents need callable endpoints.
How do I add api-mock-server to my agent?
Add https://api.lazy-mac.com/api-mock-server/mcp as a streamable-HTTP MCP remote in your agent configuration.
