Bootstrap and configure a Cratis Arc .NET host — choose AddCratis versus AddCratisArc or ArcApplication, activate Chronicle and storage integrations, disable controllers for trimming/NativeAOT, supply JSON metadata, and check identity/discovery and embedded viewer exposure. Use when creating a host, diagnosing missing endpoints, or preparing a trimmed publish. Do not use for command/query design, running a Chronicle server, or Kotlin/TypeScript hosting.

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.

# Host Arc for .NET

Choose the host and integrations before copying a bootstrap. Arc is standalone
CQRS; Chronicle is optional and its client connects to a separate event store.
Nothing in `AddCratis()` runs the Chronicle engine in your application.

How to install

The exact contents, by fingerprint
mdr add cratis/ai/cratis-arc-hosting@sha256:94e5428784f97a31

The line at the top of this page pins the label git:20261012.1578108, 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.
