Agent Maestro

Turn VS Code into your compliant AI playground! With Agent Maestro, spin up Cline or Roo on demand and plug Claude Code, Codex, or Gemini CLI straight in through an OpenAI/Anthropic/Gemini-compatible API.

Key Features

Turn VS Code into your compliant AI playground with powerful API compatibility and one-click setup:

• Universal API Compatibility: Anthropic (/messages), OpenAI (/chat/completions), and Gemini compatible endpoints - use Claude Code, Codex, Gemini CLI or any LLM client seamlessly
• One-Click Setup: Automated configuration commands for instant Claude Code, Codex, and Gemini CLI integration
• Headless AI Agent Control: Create and manage tasks through REST APIs for Roo Code and Cline extensions
  • Comprehensive APIs: Complete task lifecycle management with OpenAPI documentation at /openapi.json
  • Parallel Execution: Run up to 20 concurrent RooCode (and its variants like Kilo Code) tasks with built-in MCP server integration
  • Real-time Streaming: Server-Sent Events (SSE) for live task monitoring and message updates
  • Flexible Configuration: Workspace-level settings, environment variables, and extension auto-discovery

Quick Start

Prerequisites

Agent Maestro assumes you already installed one of the supported AI coding extensions:

• Roo Code or its variants for comprehensive API control
• Claude Code for personal development routines
• Codex for personal development routines
• Gemini CLI for personal development routines

Installation

Install the Agent Maestro extension from the VS Code Marketplace. Once activated, Agent Maestro automatically starts its API server on startup.

One-Click Setup for Claude Code

Configure Claude Code to use VS Code's language models with a single command Agent Maestro: Configure Claude Code Settings via Command Palette.

This automatically creates or updates .claude/settings.json with Agent Maestro endpoint and fills in available LLM models from VS Code.

That's it! You can now use Claude Code with VS Code's built-in language models.

One-Click Setup for Codex

Configure Codex to use VS Code's language models with a single command Agent Maestro: Configure Codex Settings via Command Palette.

This automatically creates or updates ~/.codex/config.toml with Agent Maestro endpoint and sets up GPT-5-Codex as the recommended model.

One-Click Setup for Gemini CLI

Configure Gemini CLI to use VS Code's language models with a single command Agent Maestro: Configure Gemini CLI Settings via Command Palette.

You can choose between:

• User Settings (~/.env): Personal global settings for all projects
• Project Settings (.env in workspace): Team-shared project settings in source control

This automatically creates or updates the .env file with:

• GOOGLE_GEMINI_BASE_URL: Agent Maestro Gemini endpoint
• GEMINI_API_KEY: Default authentication token (preserved if already set)
• GEMINI_MODEL: Your selected model from available VS Code language models
• GEMINI_TELEMETRY_ENABLED: Disable telemetry by default

Additionally, it creates or updates settings.json in the same folder to skip the authentication method selection on first launch:

{
  "security": {
    "auth": {
      "selectedType": "gemini-api-key"
    }
  }
}

GitHub Copilot Chat Model Enhancement

Enable additional models in GitHub Copilot Chat with the Agent Maestro: Fix GitHub Copilot Chat - Model is not supported error command. (ref)

This feature:

• Automatically locates your GitHub Copilot Chat extension
• Creates a timestamped backup before making changes
• Removes the x-onbehalf-extension-id header restriction
• Verifies the fix was applied successfully
• Prompts you to reload VS Code for changes to take effect

Note: This modification may be overwritten when the Copilot Chat extension updates. Simply run the command again after updates if needed.

Configuration

Environment Variables

You can customize Agent Maestro's server ports using environment variables:

Variable	Description	Default
AGENT_MAESTRO_PROXY_PORT	Proxy server port	23333
AGENT_MAESTRO_MCP_PORT	MCP server port	23334

Usage:

# Set custom ports
export AGENT_MAESTRO_PROXY_PORT=8080
export AGENT_MAESTRO_MCP_PORT=8081

# Launch VS Code
code .

Note: Environment variables take precedence over extension settings.

Workspace-Level Configuration

You can configure Agent Maestro settings per workspace by adding them to your project's .vscode/settings.json file:

{
  "agent-maestro.defaultRooIdentifier": "roo-cline",
  "agent-maestro.proxyServerPort": 23333,
  "agent-maestro.mcpServerPort": 23334
}

Available Settings:

Setting	Description	Default
agent-maestro.defaultRooIdentifier	Default Roo extension to use	"roo-cline"
agent-maestro.proxyServerPort	Proxy server port	23333
agent-maestro.mcpServerPort	MCP server port	23334

This allows different projects to use different configurations without affecting your global VS Code settings.

Error Diagnostics

Agent Maestro automatically logs detailed error diagnostics when API requests fail. Each extension launch creates a timestamped log file in your workspace root: {YYYY}-{MM}-{DD}_{HH}-{MM}-{SS}-{mmm}-debug.log. All errors during that session are appended to the same file.

What's logged: Request payload, transformed VSCode LM messages, error details, extension metadata, model ID, endpoint, and timestamp.

Supported endpoints:

• /api/anthropic/v1/messages (content sanitized)
• /api/openai/chat/completions (TODO: sanitization)
• /api/gemini/v1beta/models/{model}:generateContent|streamGenerateContent (TODO: sanitization)

Privacy protection:

• Anthropic only: User content is automatically redacted (text, images, documents, tool I/O, search results → [REDACTED])
• OpenAI/Gemini: Not yet sanitized - review carefully before sharing logs

Error responses include the log file path for easy troubleshooting:

{
  "error": {
    "message": "...",
    "log_file": "/path/to/workspace/2025-12-28_14-30-45-123-debug.log"
  }
}

Tip: Add *-debug.log to .gitignore to prevent committing diagnostic files.

Migration from v1.x

⚠️ Important changes when upgrading from v1.x:

1. Roo Task SSE Events Renamed

   • Events now follow RooCodeEventName enum
   • The message event remains unchanged (most commonly used)
   • Removed events: stream_closed, task_completed, task_aborted, tool_failed, task_created, error, task_resumed

2. OpenAPI Path Change

   • Old: /api/v1/openapi.json
   • New: /openapi.json

Roadmap

Our development roadmap includes several exciting enhancements:
