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

Related MCP server: IEEE 802.11 MCP Server

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!

Available Tools (V3.0.0)

Example Queries

Direct Specification Search:

"Find charging procedures in 5G service-based architecture"
→ Returns: TS 32.290 excerpts, CHF implementation details, Nchf interface specifications

Implementation Requirements:

"Extract implementation requirements for converged charging in Release 17"
→ Returns: Technical requirements, dependencies, testing considerations, compliance notes

Specification Comparison:

"Compare charging evolution from TS 32.240 to TS 32.290"
→ Returns: Evolution timeline, migration analysis, implementation impact assessment

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

V3.0.0: True MCP architecture providing direct specification access through external API integration.
