Deliver CLI

English | 简体中文

Deliver CLI is a senior-grade, state-aware Model Context Protocol (MCP) server that transforms your AI agent into a spec-driven product engineer. Version 3.0 (Agent-Optimized) is redesigned for high-density, low-token communication.

Why Deliver CLI v3?

The traditional approach to AI coding often leads to scope creep and forgotten requirements. deliver-cli (v3) is optimized for senior AI agents:

• TOON Status Output (Context Efficiency): sc_status now returns a compact, YAML-like format instead of verbose Markdown. This reduces token usage per turn by ~70%, keeping your context window lean.

• State-Aware Autopilot: The tool knows exactly what stage the project is in. The AI doesn't have to track whether it's doing "Requirements" or "Design"—it just calls mcpx with server="spec" tool="sc_plan" and instruction="Use PostgreSQL" and the tool handles the transition automatically.

• Zero-Overhead Execution: Subprocesses have been eliminated; the MCP server invokes the CLI logic directly for maximum speed and reliable error handling.

• Minimalist Syntax: Feature names and project identifiers are now optional. The tool defaults to the last-used project, reducing payload size for every subsequent tool call.

• One-Shot vs. Step-Through Modes: Users can toggle between Step-Through (the default "Draft -> Approve -> Confirm" cycle) and One-Shot mode. In One-Shot mode, the AI progresses through all phases—including archiving the project—without stopping for human approval.

• Lifecycle Directory Management: Automatically organizes work into projects/active/ and projects/completed/.

• Persistent Task-Epoch Memory: A "short-term memory" system (.epoch-context.md) that tracks active focus, pending intentions, and hypotheses via mcpx with server="spec" tool="sc_epoch" and focus="implement auth".

• The "GPS Breadcrumb" System: At the end of every tool call, deliver-cli outputs an explicit "Next Step" directive.

TOON Format (New in v3)

Instead of verbose Markdown, mcpx with server="spec" and tool="sc_status" returns a compact block:

spec_status:
  feature: code-analytics
  phase: requirements
  status: drafting
  next_step: write Requirements.md
  blockers: [template_tags_present]
  mode: one-shot

MCP Semantic Tools

Spec CLI provides a suite of surgical MCP tools to guide the AI agent through the workflow.

Command Line Interface

While primarily used via MCP, Spec CLI also provides a powerful standalone interface.

Installation & Setup

Prerequisites

• Node.js: Version 18.0.0 or higher.

• Package Manager: npm, yarn, or pnpm.

Installation Options

Option 1: Quick Start (npx)

Run it without installing globally:

npx -y @epoch-ai/deliver-cli

Option 2: Global Installation

For frequent use as a standalone CLI:

npm install -g @epoch-ai/deliver-cli

Option 3: MCP Client Configuration

To use this with AI assistants, add it to your configuration file:

Claude Desktop Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "deliver-cli": {
      "command": "npx",
      "args": ["-y", "@epoch-ai/deliver-cli"]
    }
  }
}

Gemini CLI Configure deliver-cli globally in ~/.gemini/settings.json or locally in .gemini/settings.json:

{
  "mcpServers": {
    "deliver-cli": {
      "command": "npx",
      "args": ["-y", "@epoch-ai/deliver-cli"]
    }
  }
}
