BMAD (Business-Minded Agile Development)

BMAD-MCP

Business-Minded Agile Development workflow orchestrator as an MCP (Model Context Protocol) server.

Complete agile development workflow: PO → Architect → SM → Dev → Review → QA

Interactive Requirements Gathering - Asks clarifying questions to ensure complete requirements Dynamic Engine Selection - Uses Claude by default, dual-engine when needed Content Reference System - Efficient token usage via file references Human-Readable Task Names - Organizes by task name, not UUID

🎯 What is BMAD-MCP?

BMAD-MCP is a lightweight workflow orchestrator that manages the complete agile development process. It:

• Manages workflow state (which stage you're in, what's needed next)
• Dispatches role prompts (provides detailed prompts for each role)
• Saves artifacts (PRD, architecture, code, reports)
• Does NOT call LLMs (that's Claude Code's job)

🏗️ Architecture

User → Claude Code → bmad-mcp tool
                       ↓
            Returns: {
              stage: "po",
              role_prompt: "<complete PO prompt>",
              engines: ["claude", "codex"],
              context: {...}
            }
                       ↓
Claude Code executes:
  - Calls Claude (with role_prompt)
  - Calls Codex MCP (with role_prompt)
                       ↓
Claude Code submits results → bmad-mcp
                       ↓
bmad-mcp: merges, scores, saves, advances to next stage

📋 Workflow Stages

Stage	Role	Engines	Description
PO	Product Owner	Claude + Codex	Requirements analysis (merge both)
Architect	System Architect	Claude + Codex	Technical design (merge both)
SM	Scrum Master	Claude	Sprint planning
Dev	Developer	Codex	Code implementation
Review	Code Reviewer	Codex	Code review
QA	QA Engineer	Codex	Testing and quality assurance

🚀 Quick Start

Installation (3 Steps)

# Step 1: Install globally from npm
npm install -g bmad-mcp

# Step 2: Add to Claude Code
claude mcp add-json --scope user bmad '{"type":"stdio","command":"bmad-mcp"}'

# Step 3: Verify installation
bmad-mcp
# Expected output: "BMAD MCP Server running on stdio"

That's it! Restart Claude Code and you're ready to use BMAD workflow.

Usage Example

Simply tell Claude Code to use BMAD:

User: Use bmad-task to create a user authentication system

Claude Code will:
1. Start BMAD workflow (PO stage)
2. Generate Product Requirements Document (with interactive Q&A)
3. Generate System Architecture (with interactive Q&A)
4. Create Sprint Plan
5. Implement code (using Codex)
6. Perform code review
7. Run quality assurance tests

All artifacts saved to: .claude/specs/user-authentication-system/

Configuration Location

MCP configuration is automatically added to ~/.claude/config.json:

{
  "mcpServers": {
    "bmad": {
      "type": "stdio",
      "command": "bmad-mcp"
    }
  }
}

🔧 Advanced Installation

Option 1: NPM Install (Recommended)

npm install -g bmad-mcp
claude mcp add-json --scope user bmad '{"type":"stdio","command":"bmad-mcp"}'

Option 2: Build from Source

git clone https://github.com/cexll/bmad-mcp-server
cd bmad-mcp-server
npm install
npm run build
npm link  # Makes bmad-mcp globally available

# Add to Claude Code
claude mcp add-json --scope user bmad '{"type":"stdio","command":"bmad-mcp"}'

Verify Installation

# Check if binary is available
which bmad-mcp
# Output: /usr/local/bin/bmad-mcp (or similar)

# Test the server directly
bmad-mcp
# Expected output: "BMAD MCP Server running on stdio"
# Press Ctrl+C to exit

# Restart Claude Code to load the configuration

Uninstall

# Remove from Claude Code
claude mcp remove bmad

# Uninstall npm package
npm uninstall -g bmad-mcp

📖 Usage

Basic Workflow

// 1. Start workflow
const startResult = await callTool("bmad-task", {
  action: "start",
  cwd: "/path/to/your/project",
  objective: "Implement user login system"
});

const { session_id, task_name, role_prompt, engines } = JSON.parse(startResult.content[0].text);

// 2. Execute with engines
if (engines.includes("claude")) {
  const claudeResult = await callClaude(role_prompt);
}
if (engines.includes("codex")) {
  const codexResult = await callCodexMCP(role_prompt);
}

// 3. Submit results
await callTool("bmad-task", {
  action: "submit",
  session_id: session_id,
  stage: "po",
  claude_result: claudeResult,
  codex_result: codexResult
});

// 4. Confirm and proceed (unified: saves + advances to next stage)
await callTool("bmad-task", {
  action: "confirm",
  session_id: session_id,
  confirmed: true
});

  "role_prompt": "<dev prompt>",
  "engines": ["codex"],
  "pending_user_actions": ["specify_sprint_scope_then_generate"]

Important - Dev Stage Behavior:

• After approving Sprint Plan, workflow enters Dev stage but does NOT auto-start development
• User must explicitly specify development scope:
  • "开始开发" / "start development" → Implements ALL sprints (default)
  • "开发 Sprint 1" / "implement sprint 1" → Implements only Sprint 1
• This ensures users have full control over what gets implemented and when

status - Query workflow status

{
  "action": "status",
  "session_id": "uuid"
}

Returns:

{
  "session_id": "uuid",
  "current_stage": "dev",
  "current_state": "generating",
  "stages": {...},
  "artifacts": [...]
}
