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

# librefang-extensions — agent notes

> **This file is a stub.** The previous content drifted out of sync with
> the live source (it described a `shared_client()` helper that does not
> exist, a `Vault` struct that is actually `CredentialVault`, and other
> renamed APIs). See the top-level `CLAUDE.md` "Crate map" section for
> the authoritative one-line description of this crate's role; treat the
> source files in `src/` as the canonical reference for the surface API.

## Purpose

This crate is the "everything-side-of-an-agent" toolkit that does not fit
in `librefang-runtime` or `librefang-kernel`: MCP server catalog,
credential vault, OAuth2 PKCE / Dynamic Client Registration, provider
health probes, plugin installer, shared HTTP client builder, `.env`
parsing.

## Module map (verify against `src/` before relying on this)

- `catalog` — MCP catalog metadata (`~/.librefang/mcp/catalog/`).
- `credentials` — auth-source unification (`resolve` / `resolve_all`).
- `dotenv` — `.env` parsing for agent workspaces.
- `health` — provider liveness probes.
- `http_client` — shared `reqwest` client builder
  (`client_builder()` / `new_client()` — there is no `shared_client()`;

How to install

The exact contents, by fingerprint

mdr add librefang/librefang/crates/librefang-extensions/AGENTS.md@sha256:516c7d96b5e366f6

The line at the top of this page pins the label git:20260524.7e17796, 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.
