@nitrosend/cli

The Nitrosend command-line interface. Draft campaigns, send tests, run flows, query contacts, and inspect account state — from your terminal or a CI pipeline.

All plans, including free plans, have full access to Nitrosend MCP/API/CLI. The CLI is not a paid-plan feature; plan limits apply to usage volume and paid add-ons.

npm install -g @nitrosend/cli
nitrosend login
nitrosend

Requires Node.js 18+.

Quick start

nitrosend login            # browser-based OAuth (recommended)
nitrosend                  # dashboard: account state, blockers, next actions
nitrosend status           # account health, onboarding, billing
nitrosend flows list       # your flows
nitrosend campaigns list   # your campaigns

Add --json to any command for a machine-readable envelope. nitrosend describe <command> returns the full input/output schema for any command.

What you can do

Inspect

nitrosend whoami                # active profile + endpoint
nitrosend status                # live account, billing, preflight checks
nitrosend flows list            # --status --search --page --per
nitrosend campaigns list
nitrosend contacts list         # --query --list-id
nitrosend lists list
nitrosend templates list

Agent Inbox

Agent Inbox commands are thin adapters over the existing nitro_inbox and
nitro_inbox_action tools. They require Agent Inbox access for the active
account and brand.

nitrosend inbox list --query billing       # search mailbox conversations
nitrosend inbox queue                      # prioritized items needing attention
nitrosend inbox get 123                    # bounded, sanitized thread context
nitrosend inbox item 456                   # one queue item and its thread context

nitrosend inbox reply 123 --body 'Thanks, we are on it.' --dry-run
nitrosend inbox reply 123 --body 'Thanks, we are on it.' --confirm 123
nitrosend inbox reply 123 --body 'Draft reply' --test-to [email protected] --confirm 123

nitrosend inbox action 456 mark-handled
nitrosend inbox action 456 request-human
nitrosend inbox action 456 release-to-agent
nitrosend inbox action 456 mark-quarantine

Reply and action commands receive an automatic idempotency key. Pass
--idempotency-key <key> when a caller needs to retry the same operation with a
stable key. Real replies and test sends require typed conversation confirmation;
--dry-run validates a reply without sending.

Send and automate

Send one email (or SMS with --channel sms) from your account's sender:

nitrosend send --to [email protected] --subject 'Hello' --body 'First send.'
nitrosend send --to [email protected] --subject 'Hello' --body 'First send.' --dry-run

send calls nitro_send_message with an idempotency key, so a retry with the same --idempotency-key never sends twice.

The CLI exposes the full Nitrosend MCP surface — every tool an AI agent can call, you can call too:

nitrosend mcp tools list
nitrosend mcp tools call nitro_compose_campaign --args '{...}'
nitrosend mcp tools call nitro_send_test_message --args '{...}'
nitrosend mcp tools call nitro_get_status --args '{"include":["account"]}'

Resources and prompts work the same way:

nitrosend mcp resources list
nitrosend mcp resources read nitro://account
nitrosend mcp prompts list
nitrosend mcp prompts get build-email --args '{"goal":"welcome series"}'

Inspect, plan, and replay

nitrosend describe campaigns list   # schema + examples + safety class
nitrosend recent                    # redacted history
nitrosend redo 1                    # re-run a previous command
nitrosend redo 1 --explain          # show the resolved plan, don't execute
nitrosend <any-command> --dry-run   # preview without persisting (where supported)

Authentication

OAuth (browser-based) is the default:

nitrosend login

For CI or headless environments, use an API key — either as an environment variable (nothing written to disk):

export NITROSEND_API_KEY=nskey_live_...
nitrosend status

…or stored in a local profile:

nitrosend login --api-key nskey_live_...

No account yet? Create one without a browser. The password is read from stdin, never from a flag:

printf '%s' "$PASSWORD" | nitrosend signup --email [email protected] --password-stdin

It creates the account, makes an API key for it, and stores that key as your profile.

NITROSEND_BEARER_TOKEN and NITROSEND_API_KEY always take precedence over stored profiles. nitrosend logout removes the active profile.

Pass --profile <name> to login, signup or any command to keep several accounts side by side. A project's .nitrosend.yml can name one with profile: <name>, and its commands use that profile unless a flag says otherwise.

Profiles live under your platform config directory (or NITROSEND_CONFIG_DIR if set), with directory permissions locked to your user. On shared machines, prefer the env-var form.

Output and scripting

Every command returns the same envelope under --json:

{
  "schema_version": 1,
  "ok": true,
  "command": "flows list",
  "data": { "rows": [ ... ] },
  "meta": { "duration_ms": 142, "environment": "production" },
  "presentation": { "type": "table" }
}

Errors return ok: false with a structured error object (code, message, retriable).

Useful flags:

JSON stdout is sacred: no spinners, prompts, or upgrade notices ever land there. Anything advisory goes to stderr.

Exit codes

See docs/ux-contract.md for the full UX contract.

Configuration

Project-level defaults can live in .nitrosend.yml:

profile: default
environment: production
output: json

environment is a local label: production, staging, sandbox, or development (the default). The CLI shows it on command results and in meta.environment, and production makes every destructive command ask for a typed confirmation. It is not a sandbox. It does not change the endpoint, account, or brand, and commands send real mail under every label, sandbox included.

Environment variables:

Shell completion

nitrosend completion bash >> ~/.bashrc
nitrosend completion zsh > "${fpath[1]}/_nitrosend"
nitrosend completion fish > ~/.config/fish/completions/nitrosend.fish

Upgrades

nitrosend update                       # show guidance for the installed CLI
npm install -g @nitrosend/cli@latest   # upgrade

When the API signals a newer version is available, the CLI prints a one-line stderr notice. When the installed version is below the supported minimum, authenticated commands exit non-zero before running. The CLI does not poll the npm registry.

Related packages

@nitrosend/cli is the user-facing CLI. If you're integrating Nitrosend into an MCP-aware AI host (Claude Desktop, Cursor, etc.), use @nitrosend/mcp — a stdio bridge that proxies MCP traffic from the host to the Nitrosend HTTP endpoint.
