🔍 Detecting the SVN installation

Check whether SVN is installed

# Basic command to check SVN
svn --version

# Check the full path of the executable
where svn        # Windows
which svn        # Linux/Mac

# Check the full SVN client
svn --version --verbose

Expected output if SVN is correctly installed:

svn, version 1.14.x (r1876290)
   compiled Apr 13 2023, 17:22:07 on x86_64-pc-mingw32

❌ Common errors if SVN is NOT installed:

# Windows
'svn' is not recognized as an internal or external command

# Linux/Mac
svn: command not found
bash: svn: command not found

🛠️ Advanced diagnostics

# Check the system PATH
echo $PATH                    # Linux/Mac
echo %PATH%                   # Windows CMD
$env:PATH                     # Windows PowerShell

# Search for SVN executables on the system
find / -name "svn" 2>/dev/null           # Linux
Get-ChildItem -Path C:\ -Name "svn.exe" -Recurse -ErrorAction SilentlyContinue  # Windows PowerShell

# Check the specific client version
svn --version | head -1       # Get just the first line with the version

💾 Installing SVN on Windows

Option 1: Package managers

# Using Chocolatey (Recommended)
choco install subversion

# Using winget
winget install CollabNet.Subversion

# Using Scoop
scoop install subversion

Option 2: Official installers

TortoiseSVN (includes the command-line client):

https://tortoisesvn.net/downloads.html
✅ Includes GUI and CLI clients
✅ Windows Explorer integration

SlikSVN (command line only):

https://sliksvn.com/download/
✅ Lightweight (CLI only)
✅ Ideal for automation

CollabNet Subversion:

https://www.collab.net/downloads/subversion
✅ Enterprise version
✅ Commercial support available

Option 3: Visual Studio or Git for Windows

# If you have Git for Windows installed, it can include SVN
git svn --version

# Visual Studio can also include SVN
# Go to: Visual Studio Installer > Modify > Individual Components > Subversion

🐧 Installing SVN on Linux

# Ubuntu/Debian
sudo apt-get update
sudo apt-get install subversion

# CentOS/RHEL/Fedora
sudo yum install subversion        # CentOS 7
sudo dnf install subversion        # CentOS 8/Fedora

# Arch Linux
sudo pacman -S subversion

# Alpine Linux
sudo apk add subversion

🍎 Installing SVN on macOS

# Homebrew (Recommended)
brew install subversion

# MacPorts
sudo port install subversion

# From Xcode Command Line Tools (may already be included)
xcode-select --install

🔧 Configuring SVN after installation

Check the global configuration

# Show current configuration
svn config --list

# Configure the global user
svn config --global auth:username your_username

# Configure the default editor
svn config --global editor "code --wait"     # VS Code
svn config --global editor "notepad"         # Windows Notepad
svn config --global editor "nano"            # Linux/Mac nano

Check repository access

# Test connection to a repository (without checking out)
svn list https://svn.example.com/repo/trunk

# Test with specific credentials
svn list https://svn.example.com/repo/trunk --username user --password password

🚀 Installation

From NPM

npm install -g @grec0/mcp-svn

Local Development

git clone https://github.com/gcorroto/mcp-svn.git
cd mcp-svn
npm install
npm run build

⚙️ Configuration

Environment Variables

Variable	Description	Default
`SVN_PATH`	Path to the SVN executable	`svn`
`SVN_WORKING_DIRECTORY`	Local working copy directory	`process.cwd()`
`SVN_URL` (alias: `SVN_REPOSITORY_URL`)	Repository URL. Enables URL-only workflows and `/trunk/...` target resolution	-
`SVN_USERNAME`	Authentication user	-
`SVN_PASSWORD`	Authentication password	-
`SVN_TIMEOUT`	Timeout in milliseconds	`30000`

SVN_WORKING_DIRECTORY and SVN_URL are independent — set either or both. With both configured, local operations (svn_status, svn_commit, ...) run in the working copy, and URL-capable tools (svn_cat, svn_list, svn_info, svn_log, svn_diff) can be called with:

a full URL (https://svn.example.com/repo/trunk/file.sql)
a repo-relative path starting with / (/trunk/file.sql) — joined with SVN_URL
a local path — resolved against the working copy

Example MCP Configuration

{
  "mcpServers": {
    "svn": {
      "command": "npx",
      "args": ["@grec0/mcp-svn"],
      "env": {
        "SVN_PATH": "svn",
        "SVN_WORKING_DIRECTORY": "C:/path/to/working/copy",
        "SVN_URL": "https://svn.example.com/repo",
        "SVN_USERNAME": "your_username",
        "SVN_PASSWORD": "your_password"
      }
    }
  }
}

// Status of all files
const status = await svn_status();

// Status including remote information

🐛 Troubleshooting

SVN not found

Error: SVN is not available in the system PATH

Solution: Install SVN and make sure it is on the system PATH.

Not a working copy

Error: Failed to get SVN info: svn: warning: W155007: '.' is not a working copy

Solution: Navigate to a directory that is an SVN working copy or run checkout first.

Authentication issues

Error: svn: E170001: Authentication failed

Solution: Set the SVN_USERNAME and SVN_PASSWORD environment variables.

Timeouts on long operations

Error: Command timeout after 30000ms

Solution: Increase the value of SVN_TIMEOUT.
