mock-rest-apis skillB
mock-rest-apis is agent-read markdown (skill) from mendixlabs/mxcli: Stand up an HTTP endpoint you control instead of a live third-party API, and point the Mendix app at it — Prism from an OpenAPI contract, a constant swap, or a forward proxy. Use when building or debugging a REST integration without the real API, forcing a 404/500 through an error handler, or running offline or in CI..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Mock REST APIs Skill Use this skill when a REST integration needs an endpoint you control instead of a live third-party API — while building it, while reproducing a bug, or while verifying the app in a browser or a test run. Developing against the real API means network, rate limits, credentials, and a payload that can change under you. None of that is where Mendix integration defects live: those are in the mapping, the entity types, the error handler, and the BSON. A mock removes the variables that are not the bug. ## When to Use This Skill - Building a REST client or `REST CALL` microflow before (or without) real credentials - Reproducing a payload-shaped bug **deterministically** — a shape small enough to read, that behaves the same on every run - Exercising error paths: 404, 500, a timeout, a 401 from missing auth - Verifying the app (`test-app`) or running a suite (`test-microflows`) offline or in CI - Redirecting the outbound calls of an app whose model you must not edit ## Two separate problems Almost every wasted hour here comes from conflating them: | Problem | Answer | |---|---| …

How to install
mdr add mendixlabs/mxcli/mock-rest-apis@git:20260821.ff81a24mdr add mendixlabs/mxcli/mock-rest-apis@sha256:0977dd0c400e2a92Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
