CodeAlive MCP: Deepest Context Engine for your projects (especially for large codebases)

Connect your AI assistant to CodeAlive's powerful code understanding platform in seconds!

This MCP (Model Context Protocol) server enables AI clients like Claude Code, Cursor, Claude Desktop, Continue, VS Code (GitHub Copilot), Cline, Codex, OpenCode, Qwen Code, Gemini CLI, Roo Code, Goose, Kilo Code, Windsurf, Kiro, Qoder, n8n, and Amazon Q Developer to access CodeAlive's advanced semantic code search and codebase interaction features.

What is CodeAlive?

The most accurate and comprehensive Context Engine as a service, optimized for large codebases, powered by advanced GraphRAG and accessible via MCP. It enriches the context for AI agents like Cursor, Claude Code, Codex, etc., making them 35% more efficient and up to 84% faster.

It's like Context7, but for your (large) codebases.

It allows AI-Coding Agents to:

• Find relevant code faster with semantic search

• Understand the bigger picture beyond isolated files

• Provide better answers with full project context

• Reduce costs and time by removing guesswork

Related MCP server: Codebase MCP

🛠 Available Tools

Once connected, you'll have access to these powerful tools:

1. get_data_sources - List your indexed repositories and workspaces

2. codebase_search - Semantic code search across your indexed codebase (main/master branch)

3. codebase_consultant - AI consultant with full project expertise

🎯 Usage Examples

After setup, try these commands with your AI assistant:

• "Show me all available repositories" → Uses get_data_sources

• "Find authentication code in the user service" → Uses codebase_search

• "Explain how the payment flow works in this codebase" → Uses codebase_consultant

📚 Agent Skill

For an even better experience, install the CodeAlive Agent Skill alongside the MCP server. The MCP server gives your agent access to CodeAlive's tools; the skill teaches it the best workflows and query patterns to use them effectively.

For most agents (Cursor, Copilot, Gemini CLI, Codex, and 30+ others) — install the skill:

npx skills add CodeAlive-AI/codealive-skills@codealive-context-engine

For Claude Code — install the plugin (recommended), which includes the skill plus Claude-specific enhancements:

/plugin marketplace add CodeAlive-AI/codealive-skills
/plugin install codealive@codealive-marketplace

🚀 Quick Start (Remote)

The fastest way to get started - no installation required! Our remote MCP server at https://mcp.codealive.ai/api provides instant access to CodeAlive's capabilities.

Step 1: Get Your API Key

1. Sign up at https://app.codealive.ai/

2. Navigate to MCP & API

3. Click "+ Create API Key"

4. Copy your API key immediately - you won't see it again!

Step 2: Choose Your AI Client

Select your preferred AI client below for instant setup:

🚀 Quick Start (Agentic Installation)

You may ask your AI agent to install the CodeAlive MCP server for you.

1. Copy-Paste the following prompt into your AI agent (remember to insert your API key):

Here is CodeAlive API key: PASTE_YOUR_API_KEY_HERE

Add the CodeAlive MCP server by following the installation guide from the README at https://raw.githubusercontent.com/CodeAlive-AI/codealive-mcp/main/README.md

Find the section "AI Client Integrations" and locate your client (Claude Code, Cursor, Gemini CLI, etc.). Each client has specific setup instructions:
- For Gemini CLI: Use the one-command setup with `gemini mcp add`
- For Claude Code: Use `claude mcp add` with the --transport http flag
- For other clients: Follow the configuration snippets provided

Prefer the Remote HTTP option when available. If API key is not provided above, help me issue a CodeAlive API key first.

Then allow execution.

2. Restart your AI agent.

      "headers": {
        "Authorization": "Bearer YOUR_API_KEY_HERE"
      }
    }
  }
}

Qwen Code supports MCP via mcpServers in its settings.json and multiple transports (stdio/SSE/streamable-http). Use streamable-http when available; otherwise use Docker (stdio).

~/.qwen/settings.json

{
  "mcpServers": {
    "codealive": {
      "type": "streamable-http",
      "url": "https://mcp.codealive.ai/api",
      "requestOptions": {
        "headers": {
          "Authorization": "Bearer YOUR_API_KEY_HERE"
        }
      }
    }
  }
}

Fallback: Docker (stdio)

{
  "mcpServers": {
    "codealive": {
      "type": "stdio",
      "command": "docker",
      "args": ["run", "--rm", "-i",
               "-e", "CODEALIVE_API_KEY=YOUR_API_KEY_HERE",
               "ghcr.io/codealive-ai/codealive-mcp:v0.3.0"]
    }
  }
}

Roo Code reads a JSON settings file similar to Cline.

Global config: mcp_settings.json (Roo) or cline_mcp_settings.json (Cline-style)

Option A — Remote HTTP

{
  "mcpServers": {
    "codealive": {
      "type": "streamable-http",
      "url": "https://mcp.codealive.ai/api",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY_HERE"
      }
    }
  }
}

Option B — Docker (STDIO)

{
  "mcpServers": {
    "codealive": {
      "type": "stdio",
      "command": "docker",
      "args": [
        "run", "--rm", "-i",
        "-e", "CODEALIVE_API_KEY=YOUR_API_KEY_HERE",
        "ghcr.io/codealive-ai/codealive-mcp:v0.3.0"
      ]
    }
  }
}

Tip: If your Roo build doesn't honor HTTP headers, use the Docker/STDIO option.

Using AI Agent Node with MCP Tools

1. Add an AI Agent node to your workflow

2. Configure the agent with MCP tools:

   Server URL: https://mcp.codealive.ai/api
   Authorization Header: Bearer YOUR_API_KEY_HERE

3. The server automatically handles n8n's extra parameters (sessionId, action, chatInput, toolCallId)

4. Use the three available tools:

   • get_data_sources - List available repositories

   • codebase_search - Search code semantically

   • codebase_consultant - Ask questions about code

Example Workflow:

Trigger → AI Agent (with CodeAlive MCP tools) → Process Response

Note: n8n middleware is built-in, so no special configuration is needed. The server will automatically strip n8n's extra parameters before processing tool calls.

🔧 Advanced: Local Development

For developers who want to customize or contribute to the MCP server.

Prerequisites

• Python 3.11+

• uv (recommended) or pip

Installation

# Clone the repository
git clone https://github.com/CodeAlive-AI/codealive-mcp.git
cd codealive-mcp

# Setup with uv (recommended)
uv venv
source .venv/bin/activate  # Windows: .venv\Scripts\activate
uv pip install -e .

# Or setup with pip
python -m venv .venv
source .venv/bin/activate  # Windows: .venv\Scripts\activate  
pip install -e .

Local Server Configuration

Once installed locally, configure your AI client to use the local server:

Claude Code (Local)

claude mcp add codealive-local /path/to/codealive-mcp/.venv/bin/python /path/to/codealive-mcp/src/codealive_mcp_server.py --env CODEALIVE_API_KEY=YOUR_API_KEY_HERE

Other Clients (Local)

Replace the Docker command and args with:

{
  "command": "/path/to/codealive-mcp/.venv/bin/python",
  "args": ["/path/to/codealive-mcp/src/codealive_mcp_server.py"],
  "env": {
    "CODEALIVE_API_KEY": "YOUR_API_KEY_HERE"
  }
}

Running HTTP Server Locally

# Start local HTTP server
export CODEALIVE_API_KEY="your_api_key_here"
python src/codealive_mcp_server.py --transport http --host localhost --port 8000

# Test health endpoint
curl http://localhost:8000/health

Testing Your Local Installation

After making changes, quickly verify everything works:

# Quick smoke test (recommended)
make smoke-test

# Or run directly
python smoke_test.py

# With your API key for full testing
CODEALIVE_API_KEY=your_key python smoke_test.py

# Run unit tests
make unit-test

# Run all tests
make test

The smoke test verifies:

• Server starts and connects correctly

• All tools are registered

• Each tool responds appropriately

• Parameter validation works

• Runs in ~5 seconds

Smithery Installation

Auto-install for Claude Desktop via Smithery:

npx -y @smithery/cli install @CodeAlive-AI/codealive-mcp --client claude

🌐 Community Plugins

Gemini CLI — CodeAlive Extension

Repo: https://github.com/akolotov/gemini-cli-codealive-extension

Gemini CLI extension that wires CodeAlive into your terminal with prebuilt slash commands and MCP config. It includes:

• GEMINI.md guidance so Gemini knows how to use CodeAlive tools effectively

• Slash commands: /codealive:chat, /codealive:find, /codealive:search

• Easy setup via Gemini CLI's extension system

Install

gemini extensions install https://github.com/akolotov/gemini-cli-codealive-extension

Configure

# Option 1: .env next to where you run `gemini`
CODEALIVE_API_KEY="your_codealive_api_key_here"

# Option 2: environment variable
export CODEALIVE_API_KEY="your_codealive_api_key_here"
gemini

🚢 HTTP Deployment (Self-Hosted & Cloud)

Deploy the MCP server as an HTTP service for team-wide access or integration with self-hosted CodeAlive instances.

Deployment Options

The CodeAlive MCP server can be deployed as an HTTP service using Docker. This allows multiple AI clients to connect to a single shared instance, and enables integration with self-hosted CodeAlive deployments.

Docker Compose (Recommended)

Create a docker-compose.yml file based on our example:

# Download the example
curl -O https://raw.githubusercontent.com/CodeAlive-AI/codealive-mcp/main/docker-compose.example.yml
mv docker-compose.example.yml docker-compose.yml

# Edit configuration (see below)
nano docker-compose.yml

# Start the service
docker compose up -d

# Check health
curl http://localhost:8000/health

Configuration Options:

1. For CodeAlive Cloud (default):

   • Remove CODEALIVE_BASE_URL environment variable (uses default https://app.codealive.ai)

   • Clients must provide their API key via Authorization: Bearer YOUR_KEY header

2. For Self-Hosted CodeAlive:

   • Set CODEALIVE_BASE_URL to your CodeAlive instance URL (e.g., https://codealive.yourcompany.com)

   • Clients must provide their API key via Authorization: Bearer YOUR_KEY header

See docker-compose.example.yml for the complete configuration template.

Connecting AI Clients to Your Deployed Instance

Once deployed, configure your AI clients to use your HTTP endpoint:

Claude Code:

claude mcp add --transport http codealive http://your-server:8000/api --header "Authorization: Bearer YOUR_API_KEY_HERE"

VS Code:

code --add-mcp "{\"name\":\"codealive\",\"type\":\"http\",\"url\":\"http://your-server:8000/api\",\"headers\":{\"Authorization\":\"Bearer YOUR_API_KEY_HERE\"}}"

Cursor / Other Clients:

{
  "mcpServers": {
    "codealive": {
      "url": "http://your-server:8000/api",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY_HERE"
      }
    }
  }
}

Replace your-server:8000 with your actual deployment URL and port.

🐞 Troubleshooting

Quick Diagnostics

1. Test the hosted service:

   curl https://mcp.codealive.ai/health

2. Check your API key:

   curl -H "Authorization: Bearer YOUR_API_KEY" https://app.codealive.ai/api/v1/data_sources

3. Enable debug logging: Add --debug to local server args

Common Issues

• "Connection refused" → Check internet connection

• "401 Unauthorized" → Verify your API key

• "No repositories found" → Check API key permissions in CodeAlive dashboard

• Client-specific logs → See your AI client's documentation for MCP logs
