Azure Blob Storage browser

mnml-fs-azure-blob is a terminal browser for Azure Blob Storage. Storage accounts → containers → blobs → prefixes, download to cache, yank https URIs and SAS URLs, open the Azure Portal. Runs standalone in any terminal. Shells out to az — no SDK dep. Sibling of mnml-fs-s3: same TUI shape, different cloud.

Install

cargo install --git https://github.com/chris-mclennan/mnml-fs-azure-blob mnml-fs-azure-blob
mnml-fs-azure-blob --install

You’ll also need the Azure CLI on $PATH, signed in (az login) before launching the viewer.

Setup

az login                        # interactive browser login
az account show                 # confirm subscription
mnml-fs-azure-blob              # first-run scaffolds ~/.config/mnml-fs-azure-blob.toml
mnml-fs-azure-blob --check      # verify config + CLI state

Config

refresh_interval_secs = 0       # blob listings don't churn; press `r` to refresh

[[tabs]]
name = "all accounts"
kind = "accounts"

[[tabs]]
name = "logs"
kind = "blobs"
account = "mystorageacct"       # bare account name, not the URL
container = "logs"
# prefix = "2026/"              # optional starting prefix

[[tabs]]
name = "exports"
kind = "containers"
account = "mystorageacct"

kind is one of accounts · containers (needs account) · blobs (needs account + container).

Auth shape

Every op shells out to az storage. The Azure CLI’s own credential chain handles auth:

• az login sessions work with no extra config
• Service-principal env vars (AZURE_CLIENT_ID, AZURE_TENANT_ID, AZURE_CLIENT_SECRET) flow through
• Multi-subscription: az account set --subscription <name> before launching
• --auth-mode login on every blob op means AAD RBAC applies: Storage Blob Data Reader to list; Contributor to download / delete

Keys

Chord	Action
1-9 / Tab	Switch tabs
↑ / k, ↓ / j, PgUp / PgDn, g / G	Navigate
Enter	Drill: account → containers → blobs → prefix; blob → download to ~/.cache/mnml-fs-azure-blob/<account>/<container>/<blob>
Backspace / h	Up one level
y	Yank https://<account>.blob.core.windows.net/… URL
Y	Yank SAS-signed read-only URL (5-min TTL)
o	Open Azure Portal URL for the focused row
d	Delete focused blob (y to confirm)
r	Refresh active tab
q / Esc / Ctrl+C	Quit

Two run modes

Standalone

mnml-fs-azure-blob

Hosted as a mnml Pty pane

:term mnml-fs-azure-blob

Or <leader>iA after mnml-fs-azure-blob --install.

File-open handoff — v0.1 vs v0.2

v0.1 (today): Enter on a blob downloads to ~/.cache/mnml-fs-azure-blob/<account>/<container>/<blob>. Status shows the local path. Open however you like or y-yank for later.

v0.2 (planned): Hosted-pane mode emits an OpenFile event after download so mnml can open the file in an editor pane automatically.

v0.3 (later): Save-back — remember (account, container, blob) → local path, hook mnml’s save event to push changes with az storage blob upload.
