Installation

Prerequisites

Node.js >= 18.0.0
Git LFS (for downloading pre-built data)

Quick Start (Recommended)

# Install Git LFS (if not already installed)
git lfs install

# Clone and install
git clone https://github.com/Lee-SiHyeon/mcp-server-3gpp.git
cd mcp-server-3gpp
npm install

# If chunks.json is a pointer file, pull LFS data
git lfs pull

# ✅ Ready to use! Pre-built data with 17 specs included.
npm start

Note: The pre-built chunks.json (107MB) is stored with Git LFS. If you don't have Git LFS installed, you can still use the MCP server for EMM/5GMM cause lookup, or generate data yourself using the scripts.

Included Specs

The package includes pre-processed chunks for 17 specifications:

NAS Layer (4 specs)

TS 24.008 (2G/3G NAS)
TS 24.301 (LTE NAS)
TS 24.501 (5G NAS)
TS 36.300 (E-UTRA Architecture)

TS 25.331 (3G UMTS RRC - SIB details)
TS 36.331 (4G LTE RRC - SIB details)
TS 38.331 (5G NR RRC - SIB details)

PCT - Protocol Conformance Test (4 specs)

TS 51.010-1 (2G Protocol)
TS 34.123-1 (3G Protocol)
TS 36.523-1 (4G Protocol)

TS 34.229-5 (5G IMS)

Architecture (2 specs)

TS 38.300 (5G NR)
TR 37.901 (Data Throughput)

Total: 22,408 pre-built chunks, ~107MB

Optional: Update Data

If you want to regenerate data with the latest 3GPP specifications:

# Option 1: Automatic (downloads and processes PDFs)
npm run setup

# Option 2: Manual
# Step 1: Download PDFs
npm run download-pdfs
# Step 2: Extract and chunk
npm run prepare-data

Data Preparation

✅ Pre-built Data Included (Git LFS)

This package includes pre-processed 3GPP specification data (chunks.json) with 17 specifications and 22,408 chunks (~107MB).

Important: The data file is stored using Git LFS (Large File Storage).

If you have Git LFS installed:

git lfs pull  # Download the actual data file

If you don't have Git LFS:

# Option 1: Install Git LFS (recommended)
# Windows: Download from https://git-lfs.github.com/
# Mac: brew install git-lfs
# Linux: sudo apt-get install git-lfs

git lfs install
git lfs pull

# Option 2: Manual download
# Download chunks.json from GitHub releases or generate it yourself (see below)

Without Git LFS: The MCP server will still work for EMM/5GMM cause lookup. Full document search requires the data file.

📥 Add More Specifications (Optional)

Want to add more specifications? Follow these steps:

Prerequisites

# Install Python dependencies (required for PDF processing)
pip install pymupdf

Option 1: Automatic Download

Download additional specifications automatically:

# Download PCT specs (Protocol, USIM, USAT, IMS, Architecture)
python scripts/download_pct_specs.py

# Download RRC specs (3G/4G/5G RRC with SIB details) 🆕
python scripts/download_rrc_specs.py

PCT specs include:

Protocol: TS 51.010-1 (2G), TS 34.123-1 (3G), TS 36.523-1 (4G), TS 38.523-1 (5G)
USIM/USAT: TS 31.121, TS 31.124
IMS: TS 34.229-1, TS 34.229-5
Architecture: TS 38.300, TR 37.901

RRC specs include (for SIB details):

TS 25.331 (3G UMTS RRC)
TS 36.331 (4G LTE RRC)
TS 38.331 (5G NR RRC)

Option 2: Manual Download

Download specifications manually from:

Place PDFs in the raw/ folder.

Process PDFs and Update chunks.json

After downloading PDFs:

# Step 1: Extract text from all PDFs in raw/ folder
python scripts/extract_pdf.py

# Step 2: Create chunks from extracted text
python scripts/create_chunks_simple.py

# Step 3: Copy to data folder
# Windows:
copy "extracted\chunks.json" "data\chunks.json"
# Linux/Mac:
cp extracted/chunks.json data/chunks.json

Advanced: Customize Scripts

All scripts are fully editable:

scripts/download_pct_specs.py - Modify to download different specs
scripts/extract_pdf.py - Adjust text extraction settings
scripts/create_chunks_simple.py - Change chunk size/overlap

Example: Edit download_pct_specs.py to add new specifications:

SPECS = [
    {
        'name': 'ts_your_spec',
        'series': '12300_12399',  # ETSI series folder
        'spec_num': '123001',     # Spec number
        'version': '18.00.00_60', # Target version

"Explain 5GMM cause #7"
"Find information about tracking area update"
"List all available 3GPP specifications"
"Search for SIB information in RRC specs"

Response Format

All tools return structured responses compatible with MCP SDK v1.0.0:

{
  "content": [
    {
      "type": "text",
      "text": "Human-readable response"
    }
  ],
  "structuredContent": {
    "results": [

This allows AI clients to:

Display formatted text to users
Process structured data programmatically
Integrate with automation workflows

Developer Documentation

SpecKit (Spec-Driven Development)

This project uses SpecKit for maintaining development context and collaboration.

What is SpecKit?

SpecKit is a Spec-Driven Development framework that helps developers and AI agents maintain shared context through structured specifications.

Key Principle: Specifications come first, code follows.

SpecKit Workflow

Constitution → Specify → Plan → Tasks → Implement

Constitution (.specify/constitution.md): Project principles, technical stack, historical decisions
Specs (.specify/specs/): Feature specifications with user stories and acceptance criteria
Plans (.specify/plans/): Technical implementation plans and architecture
Tasks (.specify/tasks/): Granular task breakdowns with dependencies

Using SpecKit

If you have Claude Desktop or VS Code with the SpecKit extension:

Available Slash Commands:

/speckit-constitution - View/update project constitution
/speckit-specify - Create feature specifications
/speckit-plan - Create implementation plans
/speckit-tasks - Break down tasks
/speckit-implement - Execute implementation
/speckit-clarify - Clarify ambiguous specifications
/speckit-analyze - Analyze consistency across specs
/speckit-checklist - Quality checklist
/speckit-taskstoissues - Convert tasks to GitHub Issues

Manual Access: All SpecKit files are in .specify/ directory and can be read/edited directly:

.specify/
├── constitution.md          # Project overview
├── specs/
│   └── 001-3gpp-document-search.md
├── plans/
│   └── 001-implementation-plan.md
├── tasks/
│   └── 001-tasks.md
└── templates/               # Templates for new features

Why SpecKit for this Project?

Context Sharing: NAD team and future developers have complete project history
AI Collaboration: AI agents understand design decisions and constraints
Onboarding: New contributors can read specs instead of reverse-engineering code
Documentation: Living documentation that evolves with code
