A command-line tool for using the Inkbox service from a terminal. Inkbox handles identities, email, phone and text messages, encrypted storage, contacts, notes, and webhooks.

It helps with mailbox imports, email and SMS workflows, contact management, encrypted vault operations, mail-client setup, signing keys, and webhook tasks.

It gives scripts and developers a consistent way to access Inkbox data and services without manually using a web interface. JSON output is available when another program needs to process the results.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00081	$0.11192
Opus 5	$0.00041	$0.05596
Sonnet 5	$0.00016	$0.02238
Haiku 4.5	$0.00008	$0.01119

Security

Grade A, and why

inkbox-cli scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 827 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Inkbox CLI

Command-line interface for the Inkbox API — identities, email, phone, text/SMS, encrypted vault, mailboxes, phone numbers, signing keys, and webhook utilities.

Auth & Runtime

Set credentials via env vars or global flags:

export INKBOX_API_KEY="ApiKey_..."
export INKBOX_VAULT_KEY="my-vault-key"   # only needed for vault decrypt/create flows

Global options:

--api-key <key>      Inkbox API key (or set INKBOX_API_KEY)
--vault-key <key>    Vault key for decrypt operations (or set INKBOX_VAULT_KEY)
--base-url <url>     Override API base URL
--json               Output as JSON instead of formatted tables

If INKBOX_API_KEY is missing and --api-key is not passed, the CLI exits with an error.

Prefer --json when the result will be parsed or fed into another tool. Use the default table/record output when the user wants a quick human-readable summary. With --json, success stays on stdout and API failures write one structured error object to stderr, retaining error.detail and error.retryAfterSeconds.

Install & Local Repo Usage

Published package:

npm install -g @inkbox/cli

Or run without a global install:

npx @inkbox/cli <command>

Requires Node.js >= 22.

Inside this repository, prefer running the local source instead of assuming a global install:

npm --prefix cli run dev -- <command>

Examples:

npm --prefix cli run dev -- --json identity list
npm --prefix cli run dev -- email list -i support-bot --limit 10

High-Risk Operations

These commands can send real traffic or mutate real resources. Confirm with the user before running them:

signup create
a2a invites create, a2a invites revoke, and a2a invites accept
email send
email drafts send
text send
phone call
identity delete
email delete
email delete-thread
email drafts delete
vault delete
identity update --mail-filter-mode ... / --phone-filter-mode ... (admin-only; flips allow/block semantics for that identity's channel)
mailbox update --filter-mode ... (DEPRECATED channel path; admin-only)
number release
number update --filter-mode ... (DEPRECATED channel path; admin-only)
phone incoming-action <action> / number update --incoming-call-action ... (changes what answers that identity's inbound calls — hosted_agent makes the platform voice agent pick up)
identity signing-key rotate <handle> (rotates that identity's webhook signing key)
signing-key create (DEPRECATED org-level path)

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
