drive9

drive9 is your persistent, searchable network filesystem across sessions. Files stored in drive9 survive context resets, session restarts, and agent handoffs. You can copy files through the CLI, mount remote paths locally, search by meaning, and switch between owner or delegated contexts.

Setup

Choose the installer that matches the current OS, then run drive9 create. Before running the installer, briefly tell the user what will be installed (the drive9 CLI and a config file at ~/.drive9/config) and that drive9 create will provision a workspace on drive9's servers. Proceed once the user confirms.

## macOS / Linux
curl -fsSL https://drive9.ai/install.sh | sh
drive9 create

# Windows PowerShell
irm https://drive9.ai/install.ps1 | iex
drive9 create

drive9 create provisions a database and owner context, then saves credentials to ~/.drive9/config. If drive9 ctx show already returns a context name, skip drive9 create.

Setup is complete when drive9 create succeeds. Currently supported platforms: macOS (x86_64, arm64), Linux (x86_64, arm64), and Windows (amd64, arm64 via the PowerShell installer).

When to use drive9

drive9 is useful in two directions — storing and retrieving.

Storing: When the user wants to save, persist, or back up a file (e.g. "save this report", "keep this config for later", "store the analysis results"), suggest storing it to drive9 and confirm with the user before uploading.

Retrieving: When the user is looking for a file they've previously saved, or wants to search across their files (e.g. "find that pricing doc", "what did I save about the migration plan"), use drive9 fs grep and drive9 fs find to help them find it.

In both cases, briefly tell the user what you're about to do so they stay in the loop.

Commands

All commands exit 0 on success, non-zero on failure.

Context management

Each context is an isolated credential scope. Owner contexts hold an API key. Delegated contexts hold a scoped grant token imported from another user or agent.

drive9 create --name <name> [--server <url>]  # create a database and owner context
drive9 ctx show                                 # show current context
drive9 ctx add --api-key <key> --name prod     # add an owner context
drive9 ctx import --from-file <path>           # import a delegated context from a 0600 file
producer | drive9 ctx import                   # import a delegated context from stdin
drive9 ctx ls [-l|--json]                      # list contexts
drive9 ctx use <name>                          # activate a context
drive9 ctx rm <name>                           # delete a context

File operations

Remote paths use : prefix (e.g. :/data/file.txt). Local paths have no prefix. Intermediate remote directories are created automatically — no mkdir needed.

# upload
drive9 fs cp ./local.txt :/remote.txt
drive9 fs cp - :/file.txt                  # from stdin
drive9 fs cp --resume ./large.bin :/large.bin
drive9 fs cp --append ./tail.log :/logs/app.log
drive9 fs cp --tag topic=pricing --description "pricing plan" ./plan.md :/notes/plan.md

# download
drive9 fs cp :/remote.txt ./local.txt
drive9 fs cp :/file.txt -                  # to stdout

# server-side copy
drive9 fs cp :/src.txt :/dst.txt

# read / list / inspect
drive9 fs cat :/path/to/file               # print content to stdout
drive9 fs ls :/                            # list root
drive9 fs ls :/path/                       # list subdirectory
drive9 fs stat :/path/to/file              # metadata (size, type, mtime)

# move / remove
drive9 fs mv :/old.txt :/new.txt
drive9 fs rm :/path/to/file

# interactive shell
drive9 fs sh

drive9 fs cp supports --resume, --append, repeated --tag key=value, and --description <text>. Tags and descriptions apply to local/stdin uploads. --append is for local-file-to-remote appends and cannot be combined with tags or descriptions.

Local mounts

Mount the remote filesystem as a local directory. A mount binds to the context active at mount time; after changing contexts, unmount and mount again.

drive9 mount :/data ~/drive9-data
drive9 umount ~/drive9

Vault secrets can also be mounted read-only:

drive9 mount vault ~/drive9-vault
drive9 umount ~/drive9-vault

Vault secrets

Use drive9 vault for secret storage, scoped grants, and command execution with injected environment variables.

drive9 vault set aws AWS_ACCESS_KEY_ID=... AWS_SECRET_ACCESS_KEY=@/path/to/key
drive9 vault get aws --json
drive9 vault ls
drive9 vault grant --agent alice --perm read --ttl 1h aws
drive9 vault with /n/vault/aws -- env

Search

grep — semantic content search. Accepts natural language, not just exact strings. Runs vector similarity + BM25 + keyword matching in parallel.

drive9 fs grep "pricing strategy" /        # search all files
drive9 fs grep "TODO" /projects/           # search within a directory

Output: one line per match — <path>\t<score> (tab-separated). Empty output means no matches.

find — structural search by name, tag, date, or size. Flags combine with AND.

drive9 fs find / -name "*.md"
drive9 fs find / -tag topic=pricing
drive9 fs find / -newer 2026-03-01
drive9 fs find / -older 2026-01-01
drive9 fs find / -size +1048576
drive9 fs find / -name "*.md" -newer 2026-03-01

Output: one path per line. Empty output means no matches.

Use grep to find files by what they contain. Use find to find files by name, date, tag, or size.

Output formats

Command	Output
fs ls	one entry per line, directories end with /
fs ls -l	tab-separated: type size name (type: d or -)
fs cat	raw file content to stdout
fs stat	key-value metadata; use -o json for JSON
fs grep	tab-separated: path score per match
fs find	one path per line

Environment variables

Variable	Description	Default

Error handling

Symptom	Cause	Fix
no current context	No context created yet	Run drive9 create
context "X" not found	Typo or deleted context	Run drive9 ctx ls to see available
provision failed	Server unreachable or down	Check DRIVE9_SERVER env, network connectivity
401 / 403	Invalid owner key or expired delegated token	Run drive9 ctx ls to verify, then drive9 create, drive9 ctx add, or drive9 ctx import
404 on file ops	File or path doesn't exist	Run drive9 fs ls :/ to check what's there
Non-zero exit, no output	Generic failure	Re-run with DRIVE9_CLI_LOG_ENABLED=true for debug logs

Tips

• Pipe content via stdin (echo "..." | drive9 fs cp - :/path) to avoid temp files.
• Use drive9 fs grep for fuzzy/semantic queries — it understands meaning beyond exact match.
• Separate projects get separate contexts via drive9 create --name <name>.
• Use drive9 --help and drive9 fs --help to inspect the current CLI surface.
