3GPP MCP Server V3.0.0 - Direct Specification Access

Transform your AI assistant into a 3GPP specification expert with direct access to TSpec-LLM's 535M word dataset!

What This Does

Before: Ask AI about 3GPP specifications - Get generic responses based on training data After: Ask AI + 3GPP MCP Server V3.0.0 - Get direct access to current specification content with structured, agent-ready responses

Revolutionary V3.0.0 Architecture

V3.0.0 represents the True MCP approach - lightweight API bridge providing direct specification data:

Agent Query → MCP Tools → External APIs → Real Specification Data

Key Benefits:

• True MCP Architecture - Lightweight API bridge (~10MB vs 15GB+)
• Sub-500ms responses - Intelligent caching with external API integration
• Agent-optimized - Structured JSON responses for AI agent consumption
• Real specification data - Direct access to TSpec-LLM's 535M word dataset
• External API integration - Hugging Face + 3GPP.org APIs
• Infinite scalability - Stateless API calls, no local storage limits

Quick Start (30 Seconds!)

Direct MCP Setup (Recommended)

Claude Desktop users:

claude mcp add 3gpp-server npx 3gpp-mcp-charging@latest serve

For other MCP clients: Add this to your MCP configuration:

{
  "mcpServers": {
    "3gpp-server": {
      "command": "npx",
      "args": ["3gpp-mcp-charging@latest", "serve"],
      "description": "3GPP MCP Server - Direct access to TSpec-LLM and 3GPP specifications",
      "env": {
        "HUGGINGFACE_TOKEN": "optional-for-enhanced-access"
      }
    }
  }
}

Alternative: Auto-Configuration

# One-command installation with auto-configuration
npx 3gpp-mcp-charging@latest init

# Client-specific installation
npx 3gpp-mcp-charging@latest init --client claude
npx 3gpp-mcp-charging@latest init --client vscode
npx 3gpp-mcp-charging@latest init --client cursor

Test It Works

Ask your AI assistant: "Search for 5G CHF implementation requirements in TS 32.290"

You should get structured specification content with implementation guidance, dependencies, and testing considerations!

Research Foundation

This project's V3.0.0 architecture was fundamentally inspired by the TSpec-LLM research:

TSpec-LLM: A Large Language Model for 3GPP Specifications

• Paper: https://arxiv.org/abs/2406.01768
• Authors: Rasoul Nikbakht, et al.
• Dataset: TSpec-LLM on Hugging Face

Originally planned as a document reference MCP, discovery of the TSpec-LLM research paper fundamentally changed our approach. The paper's demonstration of significant accuracy improvements (25+ percentage points) through direct LLM access to 3GPP specifications convinced us to pivot from document hosting to external API integration with their comprehensive 535M word dataset.

Technical Foundation

• Built using the Model Context Protocol SDK
• Integrates with TSpec-LLM dataset
• Supports 3GPP specifications from 3GPP.org
