Ambiance MCP Server

Unlock smarter coding: 60-80% fewer tokens, deeper insights, and seamless IDE integration

Tired of bloated code contexts wasting your AI tokens and slowing down your workflow? Ambiance MCP delivers intelligent, compressed code analysis that slashes token usage by 60-80% while preserving full semantic depth. Get precise context for debugging, understanding, and navigation—offline-ready, multi-language support, and extensible with AI or cloud features. Boost productivity in your IDE without the overhead.

Use as an MCP tool in your IDE or directly from the command line for flexible integration with your development workflow.

Why Ambiance?

• Save Tokens & Costs: Semantic compaction means fewer tokens for AI prompts, reducing expenses and speeding up responses.
• Deeper Insights Faster: AST parsing and embeddings uncover hidden patterns, helping you debug issues, trace logic, and grasp project architecture in seconds.
• Offline Power: Core features work without internet, keeping you productive anywhere.
• Seamless Integration: Plug into your IDE for real-time context, with optional AI enhancements for smarter analysis.
• Scalable for Any Project: Handles TypeScript, JavaScript, Python, Go, Rust—whether local or GitHub-based.

🚀 Quick Start

1. Install Globally

npm install -g @jackjackstudios/ambiance-mcp

2. Set Up Embeddings (For Best Results)

In your project directory:

cd /path/to/your/project
ambiance-mcp embeddings create

This enables semantic search—takes 2-10 minutes once, then auto-updates on changes.

3. Configure Your IDE

Add this to your IDE's MCP server settings. Set WORKSPACE_FOLDER to your project path.

Windows:

{
  "mcpServers": {
    "ambiance": {
      "command": "cmd",
      "args": ["/c", "npx", "-y", "@jackjackstudios/ambiance-mcp@latest"],
      "env": {
        "WORKSPACE_FOLDER": "C:\\DevelopmentDirectory\\YourProject",
        "USE_LOCAL_EMBEDDINGS": "true"
      }
    }
  }
}

macOS/Linux:

{
  "mcpServers": {
    "ambiance": {
      "command": "npx",
      "args": ["-y", "@jackjackstudios/ambiance-mcp@latest"],
      "env": {
        "WORKSPACE_FOLDER": "/path/to/your/project",
        "USE_LOCAL_EMBEDDINGS": "true"
      }
    }
  }
}

4. Go!

Ambiance auto-activates based on your setup. Add OPENAI_API_KEY for AI boosts or AMBIANCE_API_KEY for GitHub integration.

✨ Core Features & Benefits

• Semantic Code Compaction: Shrink contexts by 60-80% without losing meaning—ideal for efficient AI interactions and faster coding.
• Project Navigation & Hints: Instantly map your codebase structure, spotting key files and patterns to accelerate onboarding and refactoring.
• File & Debug Analysis: Extract symbols, explain code, and pinpoint errors using AST—saving hours on troubleshooting.
• Embeddings for Similarity Search: Offline semantic queries find relevant code chunks quickly, enhancing accuracy in large projects.
• Multi-Language Support: Works across TypeScript, JavaScript, Python, Go, Rust for versatile development.

🔧 Basic Configuration

Set these environment variables in your IDE config or terminal:

| Variable | Purpose | Required? | Default | |----------|---------|-----------|---------| | WORKSPACE_FOLDER | Your project path | Yes | Auto-detects if possible | | USE_LOCAL_EMBEDDINGS | Enable offline semantic search | No | false | | OPENAI_API_KEY | Unlock AI-powered insights | No | - | | AMBIANCE_API_KEY | Access GitHub repos | No | - |

For AI: Add OPENAI_BASE_MODEL=gpt-4 (or your preferred model) and set OPENAI_PROVIDER to target a specific vendor.
For embeddings: Set LOCAL_EMBEDDING_MODEL=all-MiniLM-L6-v2 for customization.

Provider Credentials

AI features now support multiple OpenAI-compatible providers. Set one of the following keys alongside OPENAI_PROVIDER (default: openai):

| Provider (OPENAI_PROVIDER) | Primary Key(s) | Notes | |-----------------------------|----------------|-------| | openai | OPENAI_API_KEY | Supports GPT‑5 responses API with caching metadata | | anthropic | ANTHROPIC_API_KEY, fallback OPENAI_API_KEY | Claude 3.5 / Claude 3 family | | openrouter | OPENROUTER_API_KEY, fallback OPENAI_API_KEY | OpenRouter aggregated models | | grok | XAI_API_KEY or GROK_API_KEY, fallback OPENAI_API_KEY | Grok (xAI) via OpenAI protocol | | groq | GROQ_API_KEY, fallback OPENAI_API_KEY | Groq hosted Llama models | | qwen | QWEN_API_KEY or DASHSCOPE_API_KEY, fallback OPENAI_API_KEY | Qwen compatible endpoints | | together | TOGETHER_API_KEY, fallback OPENAI_API_KEY | Together.ai models | | azure | AZURE_OPENAI_API_KEY, fallback OPENAI_API_KEY | Requires AZURE_OPENAI_ENDPOINT |

You can also set a default comparison list with AI_COMPARE_MODELS (comma-separated provider:model pairs) for the CLI comparison utility.

Advanced Usage

How Embeddings Supercharge Your Workflow

Embeddings generate in the background on first use (with USE_LOCAL_EMBEDDINGS=true), using AST fallback for immediate results. A file watcher auto-updates them every 3 minutes on changes—efficient and incremental.

Manual control via CLI:

• ambiance-mcp embeddings status – Check progress and stats.
• ambiance-mcp embeddings create --force – Regenerate all.

Available Tools

Use these via your IDE or CLI for targeted analysis.

Core (Offline):

• local_context: Compact code for queries like "authentication system".
• local_project_hints: Get architecture overviews.
• local_file_summary: Analyze files with symbols.
• local_debug_context: Debug from error logs.
• manage_embeddings: Control embeddings.

AI-Enhanced (Needs OPENAI_API_KEY):

• ai_get_context: Smarter context with AI.
• ai_project_hints: Deeper insights.
• ai_code_explanation: Auto-document code.

Cloud (Needs AMBIANCE_API_KEY):

• ambiance_search_github_repos: Find repos.
• ambiance_list_github_repos: List yours.
• ambiance_get_context: Pull repo context.

Command Line Interface

Run tools directly for testing or scripts—no IDE needed.

Key Commands:

• ambiance-mcp context --query "How does auth work?" --task-type understand
• ambiance-mcp hints --format json --use-ai
• ambiance-mcp summary src/index.ts --include-symbols
• ambiance-mcp debug "TypeError: undefined"
• ambiance-mcp grep "function $NAME($ARGS)" --language typescript
• ambiance-mcp compare --prompt "Summarize the new release notes" --models openai:gpt-5,anthropic:claude-3-5-sonnet-latest

Global options: --project-path, --format json, --output file.json, --verbose.

For full options, run ambiance-mcp --help.
