MCP Goose Subagents Server

An MCP (Model Context Protocol) server that enables AI clients to delegate tasks to autonomous developer teams using Goose CLI subagents.

Features

• Delegate to Subagents: Create specialized AI agents for different development roles
• Parallel & Sequential Execution: Run agents simultaneously or in sequence
• Recipe System: Create reusable agent configurations
• Session Management: Track and retrieve results from active subagent sessions
• Pure Goose CLI Integration: Uses only Goose CLI for subagent delegation

Prerequisites

1. Goose CLI installed and configured
2. Node.js (v18 or higher)
3. Alpha features enabled for Goose subagents

Installation

npm install

Usage

1. Add to MCP Configuration

Add this server to your MCP client configuration (e.g., mcp_config.json):

{
  "mcpServers": {
    "goose-subagents": {
      "command": "node",
      "args": ["path/to/mcp-goose-subagents/src/index.js"],
      "env": {
        "ALPHA_FEATURES": "true"
      }
    }
  }
}

2. Enable Goose Alpha Features

export ALPHA_FEATURES=true

Available Tools

      "instructions": "Review authentication implementation for security issues"
    }
  ],
  "execution_mode": "parallel"
}

Create reusable Goose recipes for specialized subagents.

Parameters:

• recipe_name (string): Name of the recipe
• role (string): Agent role
• instructions (string): Detailed instructions
• extensions (array, optional): Goose extensions to enable
• parameters (object, optional): Recipe parameters

list_active_subagents

List currently active subagent sessions and their status.

get_subagent_results

Retrieve results from completed subagent sessions.

Parameters:

• session_id (string): Session ID to get results for

Example Workflows

Autonomous Full-Stack Development

// Delegate a complete web app development task
{
  "task": "Create a todo app with React frontend and Node.js backend",
  "agents": [
    {
      "role": "project_architect",
      "instructions": "Design overall architecture and create project structure"
    },
    {
      "role": "backend_developer", 
      "instructions": "Build REST API with CRUD operations for todos"
    },
    {
      "role": "frontend_developer",
      "instructions": "Create React components and integrate with API"
    },
    {
      "role": "qa_engineer",
      "instructions": "Write tests and ensure quality standards"
    }
  ],
  "execution_mode": "sequential"
}

Parallel Code Review

{
  "task": "Review authentication module for security and performance",
  "agents": [
    {
      "role": "security_auditor",
      "instructions": "Analyze for security vulnerabilities and best practices"
    },
    {
      "role": "performance_reviewer",
      "instructions": "Identify performance bottlenecks and optimization opportunities"  
    },
    {
      "role": "code_quality_reviewer",
      "instructions": "Check code style, maintainability, and documentation"
    }
  ],
  "execution_mode": "parallel"
}

Agent Roles Examples

• backend_developer - API development, server-side logic
• frontend_developer - UI/UX implementation, client-side code
• database_engineer - Schema design, query optimization
• devops_engineer - Deployment, CI/CD, infrastructure
• qa_engineer - Testing, quality assurance
• security_auditor - Security review, vulnerability assessment
• code_reviewer - Code quality, best practices
• documentation_writer - Technical documentation, API docs
• project_architect - System design, architecture planning

Environment Variables

• ALPHA_FEATURES=true - Required for Goose subagents
• GOOSE_RECIPE_PATH - Path to custom recipe directory

Troubleshooting

1. Subagents not working: Ensure ALPHA_FEATURES=true is set
2. Goose not found: Verify Goose CLI is installed and in PATH
3. Recipe not found: Check GOOSE_RECIPE_PATH or place recipes in working directory
