Omega Tools MCP 🌌

A production-grade, highly modular Model Context Protocol (MCP) server that acts as a centralized microservice toolkit for LLM agents (Cline, Cursor, Custom Agents, etc.).

Omega is architected to decouple business logic, external clients, configuration parsing, and semantic AI tool abstractions, allowing you to seamlessly integrate new tools without restructuring your core application footprint. It supports both standard local stdio streams and scalable, production-grade SSE (Server-Sent Events) network deployment.

🏗️ Architectural Overview

The project uses a clean infrastructure layer separation pattern:

src/omega_mcp/
├── core/         # Unified system configurations, log pipelines, and constants
├── clients/      # Infrastructure connectors (Pure APIs, Databases, Web Scrapers)
├── tools/        # Semantic AI-facing interfaces decorated with @mcp.tool()
└── server.py     # Central service orchestrator and protocol router

🛠️ Current Tool Registry

  • omega_web_search: Live internet search functionality powered by optimized, lightweight web parsers.

🧱 System Architecture & Data Flow (Production SSE Mode)

In a production environment, Omega runs inside an isolated Docker container communicating via Server-Sent Events (SSE) over HTTP. This decouples it from your IDE and transforms it into a global tool mesh accessible by local editors and remote agents simultaneously.

🐳 Production Deployment via Docker

1. Build the Docker Image Locally

Run this command inside the omega-tools-mcp project directory to lock down your dependencies and build the isolated engine image:

docker build -t omega-mcp .

2. Integrate with Your Multi-Container Stack (docker-compose.yml)

To add this tool hub to your primary agent project stack (alongside ChromaDB, Neo4j, etc.), map it into your orchestration layout using port 8080 to avoid port collisions with your vector databases:

services:
  omega-mcp:
    image: omega-mcp
    container_name: nexus-tools-mcp
    ports:
      - "8080:8000" # Maps host Mac port 8080 to container internal port 8000
    environment:
      - OMEGA_ENV=production
      - OMEGA_SEARCH_MAX_RESULTS=5
    restart: unless-stopped
    depends_on:
      - redis

Boot the entire ecosystem container grid together:

docker compose up -d

🔌 Connecting to AI Clients

1. IDE Client Setup (Cline / VS Code Extension)

Once the Docker stack is active on port 8080, your IDE does not need to manage local Python runtime subprocesses. Simply swap your configuration profile inside cline_mcp_settings.json to look up the live web endpoint:

{
  "mcpServers": {
    "omega-tools-docker": {
      "url": "http://localhost:8080/sse"
    }
  }
}

2. External Project Integration (Google Gen AI SDK Agent)

To consume this microservice inside an independent custom Python Agent framework without writing complex setup commands or parameter duplications, define a clean HTTP network pass-through function:

import httpx
from google import genai

ai_client = genai.Client()

def web_search(query: str) -> str:
    """
    Executes a web search by sending an HTTP POST directly to the containerized microservice.
    """
    CONTAINER_URL = "http://localhost:8080/tools/omega_web_search/call"
    try:
        response = httpx.post(
            CONTAINER_URL, 
            json={"arguments": {"query": query}},
            timeout=30.0
        )
        response.raise_for_status()
        return response.json()["content"][0]["text"]
    except Exception as e:
        return f"Tool Error: Could not reach container server. Details: {str(e)}"

# Register straight to your Agent tool array
research_agent = Agent(
    name="ResearchAgent",
    model=ai_client,
    tools=[graph_rag_retrieval, web_search],
    instruction="Your system compliance laws here..."
)

🚀 Local Development (Non-Docker Setup)

1. Cline (VS Code Extension)

Open your global cline_mcp_settings.json and append the server into your configuration schema:

{
  "mcpServers": {
    "omega-tools": {
      "command": "uv",
      "args": [
        "--directory",
        "/path/omega-tools-mcp",
        "run",
        "src/omega_mcp/server.py"
      ],
      "env": {
        "OMEGA_SEARCH_MAX_RESULTS": "5",
        "OMEGA_ENV": "dev"
      }
    }
  }
}

2. Cursor or Windsurf

Navigate to Settings -> Features -> MCP, click + Add New MCP Server, select command mode, and set the invocation signature to:

uv --directory /absolute/path/to/your/omega-tools-mcp run omega-tools

Prerequisites

This project relies on uv for lightning-fast environment isolation. Install it on macOS using:

curl -LsSf [https://astral.sh/uv/install.sh](https://astral.sh/uv/install.sh) | sh

Setup & Diagnostic Verification

  1. Synchronize your virtual environment:

uv sync

  1. Run the standalone diagnostic validation check script:

PYTHONPATH=src uv run tests/test_search.py

📈 Scaling Up: Adding More Tools

Omega is built to expand gracefully. To introduce a new tool domain (e.g., database queries or file synchronization actions):

  1. Add Configuration Properties: Declare environment variables inside src/omega_mcp/core/config.py.

  2. Build the Infrastructure Core: Write the pure functional driver code inside src/omega_mcp/clients/.

  3. Draft Semantic Descriptions: Create the interface under src/omega_mcp/tools/ documenting parameters clearly in the docstrings so the LLM understands when to call it.

  4. Link to Orchestration Registry: Anchor it to the service endpoint inside src/omega_mcp/server.py:

from omega_mcp.tools.new_module import execute_action
mcp.tool(name="omega_new_action")(execute_action)

🔒 Security & Logging Guardrails

  • Stdout Safety: Standard print() streams interfere with JSON-RPC. All telemetry or debug trace tracking must use the custom logger omega_mcp.core.logger routing pipeline, which channels output strictly to sys.stderr.

  • Layer Isolation: Keep AI-specific framework concepts out of the clients/ folder to ensure your infrastructure layers remain simple and testable independently.
