Alternatives

• Homebrew: brew install neo4j-labs/tap/neo4j-cli (stable releases only; prereleases ship via npm/PyPI).
• npm: npm i -g @neo4j-labs/cli (also works with pnpm add -g / yarn global add). Prereleases: @alpha, @beta, @rc, @next. Platform matrix: distribution/npm/cli/README.md.
• PyPI: pip install neo4j-cli, pipx install neo4j-cli, or uv tool install neo4j-cli. One-shot: uvx -i neo4j-cli <commands>. Pin a prerelease with ==, e.g. pipx install neo4j-cli==0.1.0a6.
• Prebuilt archive: grab your OS/arch from releases.

Self-update

neo4j-cli update swaps the running binary with the latest GitHub release. By default only stable semver tags are considered.

neo4j-cli update                         # update to latest stable
neo4j-cli update check                   # report availability, exit 1 if newer; never downloads
neo4j-cli update --pre-releases          # opt into alpha/beta/rc tags
neo4j-cli update --version v0.1.0        # pin to a named tag (also the only way to downgrade)

If the binary was installed via Homebrew / npm / pipx / uv, update prints the channel-correct upgrade command instead of overwriting; pass --force to swap in place anyway. See neo4j-cli update --help.

Installed agent skill bundles are refreshed automatically after a successful swap; if none are installed, update suggests running neo4j-cli skill install.

Agent skills

neo4j-cli ships an embedded skill bundle (SKILL.md + per-subcommand references) that teaches AI coding agents how to drive the CLI. skill install drops it into each detected agent's skill directory; pass an agent name to target one.

Supported agents: Claude Code, Cursor, Windsurf, Copilot, Gemini CLI, Cline, Codex, Pi, OpenCode, Junie.

neo4j-cli skill install                  # all detected agents
neo4j-cli skill install claude-code      # one agent
neo4j-cli skill list                     # per-agent install state
neo4j-cli skill check                    # version drift vs running binary
neo4j-cli skill remove [agent]           # idempotent

Credentials

neo4j-cli stores three kinds of credentials in credentials.json under your OS config directory. All three trees share the same add / list / use / remove shape; use sets the default consumed by downstream commands.

credential aura-client — Aura Console API credentials (client ID + secret). Required for any aura ... subcommand that calls the Console API.

neo4j-cli credential aura-client add --name "my-org" --client-id <id> --client-secret <secret>
neo4j-cli credential aura-client list
neo4j-cli credential aura-client use my-org
neo4j-cli credential aura-client remove my-org

credential dbms — Neo4j Bolt connection profiles (URI, username, password, database, optional embed-credential link). When a default profile exists, neo4j-cli query connects without any connection flags or env vars.

neo4j-cli credential dbms add --name prod --uri neo4j+s://example.databases.neo4j.io --username neo4j --password '<pw>'
neo4j-cli credential dbms list
neo4j-cli credential dbms use prod
neo4j-cli credential dbms set-embed prod openai-shared    # link an embed credential
neo4j-cli credential dbms set-embed prod                  # clear the link
neo4j-cli credential dbms remove prod

credential embed — Embedding-provider credentials (provider, model, base URL, dimensions, optional API key). Consumed by query --param NAME:embed=... and query :embed. Supported providers: openai, ollama, huggingface.

neo4j-cli credential embed add --name openai-shared --provider openai --model text-embedding-3-small --api-key '<key>'
neo4j-cli credential embed list                           # api-key is never printed
neo4j-cli credential embed use openai-shared
neo4j-cli credential embed remove openai-shared

Aura

Manage Neo4j Aura instances from the terminal. Requires an aura-client credential — create one in your Aura Account Settings and add it via Credentials above.

List your instances

neo4j-cli aura instance list --format table

Create an instance

# Free-db — no cloud provider, region, or memory required
neo4j-cli aura instance create --name my-free-db --type free-db --tenant-id <tenant-id> --rw

# Professional-db on AWS, awaiting readiness
neo4j-cli aura instance create --name my-pro-db --type professional-db --cloud-provider aws \
  --region us-east-1 --memory 4GB --tenant-id <tenant-id> --await --rw

aura tenant list shows tenant IDs. Initial DB credentials returned by instance create are auto-stored as a dbms credential (named <instance-id>-default), so neo4j-cli query can connect immediately. Use --no-credential-storage to skip that.

Querying Neo4j

neo4j-cli query runs Cypher against any Neo4j database via the Bolt protocol. Cypher comes from the positional argument or piped stdin.

neo4j-cli query 'RETURN 1 AS n'
echo 'MATCH (n) RETURN count(n)' | neo4j-cli query

Preferred: add a dbms credential (see Credentials) and query connects with no further config. aura instance create auto-stores one for new instances.

Flags, env vars, and .env files are optional overrides — useful for one-offs or CI without persisting a credential. When a stored credential exists, an override must supply all four of URI/username/password/database (any partial set is rejected). Without a stored credential, resolution is flag → env var → .env file (auto-discovered walking up from cwd) → built-in default.

.env discovery walks up from cwd and stops at the first .git ancestor or your $HOME boundary (whichever comes first), so a .env outside your repo or above your home directory is never loaded. When the loaded .env lives strictly above cwd, an info: loading .env from <path> line is printed to stderr so the overlay is never silent.

Setting	Flag	Env var	Default
URI	--uri	NEO4J_URI	neo4j://localhost:7687
Username	--username	NEO4J_USERNAME	neo4j
Password	--password	NEO4J_PASSWORD	prompted on TTY
Database	--database	NEO4J_DATABASE	neo4j

http:// and https:// URIs are auto-rewritten to neo4j://<host>:7687 and neo4j+s://<host>:7687 respectively (path/query stripped). For self-signed certs use neo4j+ssc://.

Pass parameters with --param key=value (repeatable). Values that parse as JSON are typed; everything else is a string:

neo4j-cli query 'MATCH (p:Person {name:$name}) RETURN p' --param name=Alice
neo4j-cli query 'RETURN $ids' --param 'ids=[1,2,3]'
echo 'MATCH (p:Person {name:$name}) RETURN p' | neo4j-cli query --param name=Alice

Output is a table by default; pass --format json for a stable envelope (columns, rows, truncated, arrays_truncated). When stdout is not a terminal (piped or redirected), --format defaults to json. Applies to both query and :schema. Large results are capped at 100 rows and arrays inside cells at 100 items — tune with --max-rows / --truncate-arrays-over (0 = unlimited).

Schema introspection:

neo4j-cli query :schema

Embedding parameters

Bind a vector parameter inline by passing --param NAME:embed=<text> — the text is sent to the configured embedding provider and the resulting []float32 is bound to $NAME for both the EXPLAIN preflight and the real run. The sibling query :embed [text] leaf computes a vector standalone without opening a Bolt connection.

neo4j-cli query --param q:embed='sci-fi movies' --param k=5 \
  "CALL db.index.vector.queryNodes('idx', \$k, \$q) YIELD node, score RETURN node, score"

neo4j-cli query :embed "hello world" --format json
echo "hello world" | neo4j-cli query :embed --format toon

Embedding settings resolve with this precedence (highest first): flag → env var → .env file → stored embed credential → provider built-in default.

Setting	Flag	Env var
Credential	--embed-credential	—
Provider	--embed-provider	NEO4J_EMBED_PROVIDER
Model	--embed-model	NEO4J_EMBED_MODEL
Base URL	--embed-base-url	NEO4J_EMBED_BASE_URL
Dimensions	--embed-dimensions	NEO4J_EMBED_DIMENSIONS
API key	(none — see below)	NEO4J_EMBED_API_KEY, OPENAI_API_KEY, HF_TOKEN

API-key precedence (highest first): per-provider OS env (OPENAI_API_KEY / HF_TOKEN) → generic OS env (NEO4J_EMBED_API_KEY) → per-provider .env value → generic .env value → stored credential api-key. Ollama needs no API key.

--embed-credential <name> selects a stored embed credential explicitly; without it the resolver falls back to the embed credential linked from the resolved dbms credential (via credential dbms add --embed-credential or credential dbms set-embed), then to credential embed's default. So one --credential <name> can drive both DB connection and embedding when the dbms credential carries an embed link.

Provider defaults: OpenAI base URL https://api.openai.com/v1, Ollama http://localhost:11434, HuggingFace https://router.huggingface.co/hf-inference/models (serverless mode). Setting --embed-base-url switches HuggingFace to dedicated-endpoint mode.

Write operations

Write commands require --rw. neo4j-cli query runs EXPLAIN first when --rw is absent and blocks mutating Cypher before execution.

neo4j-cli aura instance delete <id> --rw
neo4j-cli config set telemetry false --rw
neo4j-cli query 'CREATE (:Person {name:"Alice"})' --rw
