OrbitMCP

Edge-Native Model Context Protocol (MCP) Control Plane & Autonomous Tool Dispatcher

A lightweight, air-gapped desktop cockpit connecting local LLMs (Llama 3.2) to standard MCP tools with deterministic hardware safety.

The Core Problem

Standard Large Language Models—both proprietary cloud APIs and local weights—are isolated text predictors. They are fundamentally blind to the physical machine they execute on:

1. No Native Hardware Awareness: An LLM cannot independently check remaining VRAM, inspect project repositories, run shell routines, or read SQLite databases without external glue code.

2. Cloud Privacy & Egress Risk: Transmitting proprietary codebase structures, internal documents, and host machine telemetry across cloud APIs introduces recurring token costs and data compliance vulnerabilities.

3. Electron Bloat: Existing agent GUIs frequently rely on Electron, consuming 800MB–1.5GB of RAM before an inference model even loads into memory.

What OrbitMCP Solves

OrbitMCP converts your local workstation into a zero-latency, air-gapped agent environment.

Built with a native Rust (Tauri v2) shell and a Python FastMCP sidecar, OrbitMCP operates at under 100MB RAM overhead, reserving your system resources entirely for model weights and fast local inference.

Key Features

1. Autonomous MCP Tool Execution Loop

OrbitMCP translates user queries into OpenAI-compatible tool specifications for local Ollama models. When a query requires OS context, the model interrupts standard generation, dispatches structured tool arguments to the FastMCP gateway, executes the Python script locally, and summarizes the final payload.

2. Live Kernel Telemetry Polling

Direct hardware polling via psutil monitors CPU core utilization, resident RAM consumption, and available memory headroom every 3 seconds to prevent Out-Of-Memory (OOM) lockups during heavy inference.

3. Claude-Style Thinking Process Block

Includes an oscillating 4-bar waveform animation and live elapsed timer (Thought for 11.4s). Thinking blocks can be collapsed into an internal monologue scratchpad detailing schema resolution and safety boundary checks.

4. Four Curated Developer Themes

Includes four high-contrast developer color palettes switchable at runtime with instant token re-rendering:

• Obsidian Amber (Dark Charcoal + Warm Amber)

• Tokyo Violet (Cyber Synth Indigo + Purple)

• Matrix Emerald (Terminal Green + Jet Black)

• Linear Cobalt (Deep Space Slate + Sky Blue)

5. Dynamic Model Discovery & Parameter Tuning

• Model Dropdown: Auto-queries the local Ollama daemon on launch (/api/tags) to populate installed weights (llama3.2:3b, qwen2.5-coder, mistral, etc.).

• Sampling Temperature: Integrated slider (0.0 to 1.0) to dynamically adjust generation determinism.

• Tool Gating: Independent toggles on each tool card to enable or disable specific MCP functions from the model's schema dynamically.

Getting Started

Prerequisites

Ensure the following runtimes are installed on your host system:

• Node.js (v18.0 or later)

• Python (v3.10 to v3.12)

• Rust & Cargo (for Tauri desktop compilation)

• Ollama (with llama3.2:3b pulled)

Installation & Setup

1. Clone the Repository

git clone [https://github.com/Velocity07/OrbitMCP.git](https://github.com/Velocity07/OrbitMCP.git)
cd OrbitMCP

2. Configure the Python FastMCP Backend

Create and activate a virtual environment, then install the dependencies:

# Windows PowerShell
python -m venv .venv
.\.venv\Scripts\Activate.ps1

# Install backend requirements
pip install -r backend/requirements.txt

3. Install Frontend Dependencies

npm install

4. Pull the Local Inference Model

Ensure Ollama is running, then pull the default lightweight tool-calling model:

ollama pull llama3.2:3b

Running OrbitMCP

Step A: Start the FastMCP Backend Server

In your first terminal (with .venv activated):

python backend/server.py

The gateway will initialize on http://127.0.0.1:8765.

Step B: Launch the Native Desktop Window

In your second terminal:

npx tauri dev

OrbitMCP will compile the native Rust binary, launch the desktop window, and automatically establish a live IPC bridge with the FastMCP backend.

Writing Custom FastMCP Tools

OrbitMCP is designed to be easily extensible. To register a new tool with the agent loop:

1. Define your tool function in backend/tools/ using FastMCP:

# backend/tools/network.py
import socket
from typing import Dict, Any

def test_port(host: str, port: int) -> Dict[str, Any]:
    """Check if a specific host and port is accepting connections."""
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.settimeout(2.0)
    try:
        s.connect((host, port))
        s.close()
        return {"host": host, "port": port, "open": True}
    except Exception as e:
        return {"host": host, "port": port, "open": False, "error": str(e)}

2. Register the tool decorator and schema in backend/server.py:

from tools.network import test_port

@mcp.tool()
def check_port(host: str, port: int) -> Dict[str, Any]:
    """Test connection status for a remote host and port."""
    return test_port(host, port)

3. Restart server.py. The tool will instantly populate in the Registered Tools panel and be available for autonomous invocation.
