Common questions

Is i18n-agent safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: I18N_AGENT_API_KEY

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.16.3) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

🔧 Manual Setup

If auto-installation fails, you can manually configure your IDE:

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

"mcpServers": { "i18n-agent": { "command": "node", "args": ["/path/to/i18n-agent.js"], "env": { "MCP_SERVER_URL": "https://mcp.i18nagent.ai", "I18N_AGENT_API_KEY": "your-api-key-here" } } } }

Cursor / VS Code

Create .cursor/mcp_settings.json or .vscode/mcp_settings.json:

"mcpServers": { "i18n-agent": { "command": "node", "args": ["/path/to/i18n-agent.js"], "env": { "MCP_SERVER_URL": "https://mcp.i18nagent.ai", "I18N_AGENT_API_KEY": "your-api-key-here" } } } }

💡 Usage Tips

Translation Context

Target Audience: Specify "technical", "casual", "formal", or "general"
Industry Context: Use "technology", "healthcare", "finance", "education"
Regional Variations: Add regions like "Spain", "Mexico", "Brazil"

File Translation

Preserve Structure: Keeps original file format and structure
Output Format: Convert between formats (JSON ↔ YAML ↔ CSV)
Large Files: Automatically chunks large files for processing
Async Processing: Files >50KB processed asynchronously with job tracking
Progress Monitoring: Real-time status updates for long-running translations
Timeout Resilience: Up to 10 minutes for large translation jobs

Large Translation Handling

Async Processing: >100 texts or >50KB files processed asynchronously
Job Tracking: Unique job IDs for monitoring long-running translations
Progress Updates: Real-time completion percentages and status
Extended Timeouts: 5-10 minute timeouts prevent interruptions
Automatic Polling: Client automatically polls for job completion

Credit Management

Cost: 1 credit per word ($0.01/word)
Monitoring: Check balance before large translations
Estimates: Get word count estimates before translation

Quality Warnings

Source Analysis: By default, source content is analyzed for quality issues before translation
Skip Warnings: Use skipWarnings: true to bypass warnings in automated workflows
Trade-off: Skipping warnings may reduce translation quality as potential issues aren't addressed
Best Practice: Keep warnings enabled (default) for production translations

🚨 Troubleshooting

Installation Issues

Permission denied:

sudo npm install -g @i18n-agent/mcp-client

IDE not detected:

# Check if IDE directory exists

ls ~/Library/Application\ Support/Claude/ ls ~/.cursor/ ls ~/.vscode/

MCP Connection Issues

"Failed" status in Claude Code:

This usually happens with Node Version Managers (nvm, fnm, n). The installer now automatically detects nvm and creates a wrapper script. If you still have issues:

Check your Node installation:

   which node

If output contains .nvm, you're using nvm

Manual wrapper script (if auto-detection fails): Create ~/.claude/run-mcp.sh:

   #!/bin/bash

export PATH="$(dirname $(which node)):$PATH" cd ~/.claude exec node node_modules/@i18n-agent/mcp-client/i18n-agent.js

Make it executable:

   chmod +x ~/.claude/run-mcp.sh

Update Claude configuration: Edit ~/.claude.json:

"mcpServers": { "i18n-agent": { "command": "/Users/YOUR_USERNAME/.claude/run-mcp.sh", "env": { "MCP_SERVER_URL": "https://mcp.i18nagent.ai", "I18N_AGENT_API_KEY": "your-api-key" } } } }

Restart Claude Code completely (not just close window, quit the app)

Runtime Issues

API Key not found:

echo $I18N_AGENT_API_KEY  # Should show your key

export I18N_AGENT_API_KEY=your-key-here

Connection errors:

Check your internet connection
Verify API key is valid
Try again after a few seconds

Translation quality:

Use Tier 1 languages for production
Add context with industry/audience parameters
Review Tier 2/3 translations manually

📊 Pricing

Pay-per-use: 1 credit per word ($0.01/word)
No subscriptions: Only pay for what you translate
Bulk discounts: Available for enterprise usage
Free tier: New accounts get starter credits

🔐 Privacy & Security

No data storage: Translations are processed in real-time
Encrypted transport: All data sent over HTTPS
API key security: Keys are stored locally, never transmitted in logs
GDPR compliant: EU privacy standards

🏗️ Architecture

The MCP client installer uses a modular architecture for bulletproof installation:

lib/

├── config-manager.js # Config file operations with atomic writes ├── installer-core.js # Installation orchestration ├── transport-detector.js # Auto-detect SSE vs stdio transport └── validator.js # Input validation and sanitization

Key Features

Atomic Config Writes: Use temp files + rename for crash safety
Automatic Backups: Create timestamped backups before modifications
Transport Detection: Auto-detect SSE vs stdio from config
Comprehensive Validation: Validate all inputs at module boundaries
Zero External Dependencies: Uses only Node.js built-ins
