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!

MCP Compatible Node.js Version License: BSD-3-Clause

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!

Available Tools (V3.0.0)

Tool	Purpose	Input	Output
`search_specifications`	Direct TSpec-LLM search	Query + filters	Structured spec results + relevance scores
`get_specification_details`	Comprehensive spec details	Specification ID	Full metadata + implementation guidance
`compare_specifications`	Multi-spec comparison	Array of spec IDs	Comparison matrix + migration analysis
`find_implementation_requirements`	Requirements extraction	Spec scope + focus	Technical requirements + testing guidance

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.

How are these scores calculated?

remote-capable server

The server can be hosted and run remotely because it primarily relies on remote services or has no dependency on the local environment.

Tools

Enables AI assistants to access and search 3GPP telecommunications specifications through direct integration with the TSpec-LLM dataset. Provides real-time specification content, implementation requirements, and multi-spec comparisons for 3GPP standards development.
