Use when writing a client for someone else's REST or GraphQL API: auth flow choice and token refresh, pagination to exhaustion, retry-with-jitter on transient failures only, rate-limit-aware throttling. NOT inbound callbacks (that is `webhooks`), NOT chaining services (that is `automation-flows`), NOT designing your own API (that is `api-design`).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# API connector builder — auth, pagination, retries, rate limits You are writing a client for **someone else's** HTTP API. You do not own the contract; you obey it. The deliverable is one typed connector module per vendor that authenticates, walks the whole result set, retries only transient failures with backoff, and stays under the rate limit without getting the key banned. One connector = one vendor: mixed clients tangle two auth schemes and two rate-limit budgets into something no one can reason about. Four pillars, every time: **auth, pagination, retries, rate limits.** If your connector skips any one of them it works in the demo and breaks in production — on page 2, on token expiry, on the first 429, or on a flaky network. ## Step 0 — read the contract Read the vendor docs before writing a line — invented endpoints and guessed field names 404 in prod. Extract these first; each one changes what you write, so missing one means a rewrite. | Find in their docs | Why it changes your code | | ------------------------- | --------------------------------------------------------- | …

How to install
mdr add ericrisco/rsc-harness/api-connector-builder@sha256:dd35fdbbe462b0fcThe line at the top of this page pins the label git:20260729.3ecb845, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
