Serveur MCP Nitrosend

@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 <command> --help prints a command's usage and examples, and nitrosend describe <command> --json returns its input schema (every flag, its type and allowed values, and which are required), safety class and examples.

What you can do

Inspect

nitrosend whoami                # active profile + the MCP endpoint the CLI calls
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 me@example.com --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 you@example.com --subject 'Hello' --body 'First send.'
nitrosend send --to you@example.com --subject 'Hello' --body 'First send.' --dry-run

send calls nitro_send_message, which requires an idempotency key. The CLI makes one for each run; pass your own --idempotency-key to retry the same send safely, since a retry with the same 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

It opens your browser and prints the sign-in URL to stderr. With --no-browser it only prints the URL, for a remote shell or another device.

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 you@example.com --password-stdin

Signup returns verification_required and leaves your current profile untouched. Read the verification email, then supply JSON containing its token and your final password through stdin:

nitrosend signup verify --verification-stdin --profile default < verification.json

Keep that input file private and remove it after use, or stream the JSON directly from your secret store. Do not put passwords or verification tokens in command arguments. Verification creates the account, makes an API key, and saves that key as the profile. The final password replaces the password used to start signup.

If the link expires, run nitrosend signup resend --email you@example.com. If verification succeeded but activation, key creation or local profile storage was interrupted, resume without another email:

printf '%s' "$PASSWORD" | nitrosend signup resume --email you@example.com --password-stdin --profile default

Use the same --api-url and --profile throughout. Resending has a one-minute cooldown and three-per-address daily limit; global acquisition limits also apply. Respect Retry-After on HTTP 429. Existing API-key and browser OAuth login remain available.

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 },
  "presentation": { "type": "table" }
}

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

Useful flags:

Flag	Effect
--json, --ndjson, --csv	Output mode
--machine	Implies --json --non-interactive --no-color --no-pager
--explain	Print the resolved plan; don't execute
--dry-run	Preview changes without persisting (where supported)
--idempotency-key <key>	Supply a stable retry key for idempotent mutations
--yes	Skip non-destructive confirmations (typed confirmation still required for destructive ops)
--non-interactive	Fail closed when input would be required
--trace	Write a structured trace to stderr

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

Exit codes

Code	Meaning
0	Success
64	Usage error
65	Validation or data error
69	Service unavailable / network error
70	Internal error
75	Temporary, retriable failure
77	Authentication or permission error
78	Unsupported / outdated CLI

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, and there is none unless the file sets one. 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:

Variable	Purpose
NITROSEND_API_KEY	API key (highest precedence)
NITROSEND_BEARER_TOKEN	Pre-issued OAuth token
NITROSEND_API_URL	Override the default endpoint (https://api.nitrosend.com/mcp)
NITROSEND_CONFIG_DIR	Custom profile storage path

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.
