3GPP MCP Server

An MCP (Model Context Protocol) server that provides LLMs with access to 3GPP telecom protocol specifications and enables intelligent querying of technical documentation.

Features

• Semantic Search: Search through 3GPP specification documents using natural language queries
• Specification Details: Get detailed information about specific 3GPP specifications
• Protocol Information: Query information about 3GPP protocols and procedures
• Related Documents: Find specifications related to specific topics
• Resources: Access to specification catalogs, protocol lists, and release timelines
• Prompts: Pre-written templates for common 3GPP-related queries

Installation

1. Clone this repository

2. Install dependencies:

   npm install

3. Build the project:

   npm run build

4. (Optional) Download TSpec-LLM dataset:

   node dist/download-dataset.js

Usage

With Claude Desktop

1. Add the server configuration to your Claude Desktop config file:

{
  "mcpServers": {
    "3gpp-server": {
      "command": "node",
      "args": ["dist/index.js"],
      "cwd": "/path/to/3gpp-mcp-server"
    }
  }
}

2. Restart Claude Desktop
3. The server will be available with the following tools:

Available Tools

search_3gpp_specs

Search through 3GPP specification documents using semantic search.

Parameters:

• query (string, required): Search query text
• series (array, optional): Filter by specification series (e.g., ["24", "25"])
• releases (array, optional): Filter by 3GPP releases (e.g., ["Rel-15", "Rel-16"])
• limit (number, optional): Maximum number of results (1-50, default: 10)
• offset (number, optional): Offset for pagination (default: 0)

get_specification_details

Get detailed information about a specific 3GPP specification.

Parameters:

• specId (string, required): Specification ID (e.g., "TS 24.301")
• format (string, optional): Level of detail - "summary", "detailed", or "raw" (default: "summary")

query_protocol_info

Get information about specific 3GPP protocols and procedures.

Parameters:

• protocolName (string, required): Name of the protocol (e.g., "NAS", "RRC")
• queryType (string, optional): Type of information - "procedures", "messages", or "overview" (default: "overview")

find_related_specs

Find specifications related to a given topic or specification.

Parameters:

• topic (string, required): Topic or specification to find related documents for
• maxResults (number, optional): Maximum number of related specs to return (default: 5)

Available Resources

• 3gpp://specifications/catalog: Complete catalog of available 3GPP specifications
• 3gpp://protocols/list: List of all 3GPP protocols with descriptions
• 3gpp://releases/timeline: Timeline of 3GPP releases and their major features

Available Prompts

• explain_3gpp_procedure: Explain a specific 3GPP procedure in detail
• compare_specifications: Compare two 3GPP specifications highlighting differences

Example Usage

Once integrated with Claude Desktop, you can use natural language queries like:

• "Search for NAS authentication procedures in LTE specifications"
• "Show me details about TS 24.301"
• "What are the key procedures in RRC protocol?"
• "Find specifications related to 5G security"
• "Explain the attach procedure in detail"
• "Compare TS 36.331 and TS 38.331"

Architecture

The server consists of several key components:

• Specification Manager: Handles loading and managing 3GPP specifications
• Search Engine: Provides semantic search capabilities across documents
• Document Processor: Extracts and processes content from specification documents
• MCP Server: Implements the Model Context Protocol interface

Data Source

This server is designed to work with the TSpec-LLM dataset, which contains processed 3GPP documentation from Release 8 to Release 19. The dataset is available at: https://huggingface.co/datasets/rasoul-nikbakht/TSpec-LLM
