Instantly CLI

Instantly.ai in your terminal. Run cold email campaigns, manage leads, monitor deliverability, and automate every outbound motion — from a single command line.

156 commands across 31 API groups. Full coverage of the Instantly.ai V2 API. Built for humans, scripts, CI/CD pipelines, and AI agents.

npm install -g instantly-cli

What is Instantly?

Instantly.ai is the leading cold email and outbound sales platform. It handles everything needed to run high-volume outbound at scale:

• Email infrastructure — connect unlimited sending accounts (Google Workspace, Microsoft 365, SMTP/IMAP), auto-rotate senders, manage warmup
• Campaign management — multi-step email sequences with A/B testing, scheduling, and conditional logic
• Lead management — import, enrich, deduplicate, and track prospects across campaigns
• Deliverability — inbox placement testing, sender reputation monitoring, blocklist management, and warmup analytics
• Unified inbox — read, reply, and forward across all sending accounts from one place
• AI features — AI-powered lead labeling, interest classification, and response handling

What This CLI Enables

The Instantly CLI gives you programmatic access to the entire platform. Every action you can take in the Instantly dashboard, you can do from your terminal:

Campaign operations — create campaigns, add leads, launch sequences, pause/resume, duplicate, and monitor sending status without opening a browser.

Lead lifecycle — import leads in bulk, move them between campaigns, update interest status, merge duplicates, assign to subsequences, and manage labels — all scriptable.

Account management — connect sending accounts, enable/disable warmup, test DNS/SMTP/IMAP health, pause underperforming senders, and monitor CTD (click-to-deliver) status.

Deliverability monitoring — run inbox placement tests, analyze where emails land (inbox vs. spam vs. promotions), track ESP-level performance, and get actionable insights.

Analytics & reporting — pull campaign stats, daily breakdowns, per-step sequence analytics, warmup performance, and account-level sending volumes into any reporting tool.

Team & workspace admin — manage workspace members, API keys, billing info, audit logs, and whitelabel domains.

AI agent integration — every command works as both a CLI subcommand and an MCP tool, so AI assistants (Claude, Cursor, Windsurf) can manage your outbound directly.

MCP Server

The CLI doubles as an MCP (Model Context Protocol) server, giving AI assistants direct access to all 156 Instantly tools as native function calls.

instantly mcp

What this means

When you configure instantly mcp as an MCP server in Claude, Cursor, VS Code, or Windsurf, your AI assistant can:

• Create and launch campaigns mid-conversation
• Look up lead data and analytics on demand
• Reply to emails, manage accounts, and run enrichment
• Automate multi-step outbound workflows end-to-end

Every CommandDefinition in the codebase powers both a CLI subcommand and an MCP tool — one source of truth, two interfaces.

Configuration

Add to your MCP settings (Claude Desktop, Cursor, VS Code, Windsurf):

{
  "mcpServers": {
    "instantly": {
      "command": "npx",
      "args": ["instantly-cli", "mcp"],
      "env": {
        "INSTANTLY_API_KEY": "your-api-key"
      }
    }
  }
}

This registers 156 tools across 31 groups:

Architecture

The CLI uses a CommandDefinition pattern where every API endpoint is defined as a single object that powers both the CLI subcommand and the MCP tool:

src/
├── core/
│   ├── client.ts      # HTTP client with retry, rate limiting, pagination
│   ├── auth.ts        # API key resolution (flag → env → config)
│   ├── output.ts      # JSON output formatting
│   └── types.ts       # CommandDefinition interface
├── commands/
│   ├── campaigns/     # 11 commands
│   ├── leads/         # 12 commands
│   ├── accounts/      # 12 commands
│   └── ...            # 28 more groups
└── mcp/
    └── server.ts      # MCP server (auto-registers all commands as tools)

Adding a new API endpoint = creating one file. The command is automatically available in both CLI and MCP.

HTTP Client Features

• Auto-retry with exponential backoff on 429 (rate limit) and 5xx errors
• Rate limit awareness — respects Retry-After headers
• Cursor-based pagination — handles both UUID and datetime cursors
• 30-second timeout with configurable retries (default: 3)
• Typed errors — AuthError, NotFoundError, RateLimitError, ValidationError, ServerError

Development

git clone https://github.com/bcharleson/instantly-cli.git
cd instantly-cli
npm install

npm run dev -- campaigns list    # Run in dev mode (tsx)
npm run build                    # Build with tsup
npm test                         # Run tests (138 tests, vitest)
npm run typecheck                # Type-check (tsc --noEmit)

Tech Stack

• TypeScript (ESM, Node 20+)
• Commander.js — CLI framework
• Zod — schema validation (shared between CLI and MCP)
• @modelcontextprotocol/sdk — MCP server
• tsup — bundler
• vitest — test runner
