## MCP Client Integration
Claude Desktop (`~/Library/Application Support/Claude/claude_desktop_config.json`):
```json
{
"mcpServers": {
"youtrack": {
"command": "node",
"args": ["/abs/path/youtrack-mcp/dist/index.js"],
"env": {
"YOUTRACK_URL": "https://your-instance.youtrack.cloud",
"YOUTRACK_TOKEN": "token",
"PROJECT_ID": "PRJ" // Optional
}
}
}
}
```
VSCode (`.vscode/settings.json`):
```json
{
"servers": {
"youtrack": {
"command": "node",
"args": ["./dist/index.js"],
"env": {
"YOUTRACK_URL": "https://your-instance.youtrack.cloud",
"YOUTRACK_TOKEN": "token",
}
}
}
}
```
Github Coding Agent:
```json
"mcpServers": {
"youtrack": {
"type": "sse",
"url": "https://your-instance.youtrack.cloud/mcp/sse",
"headers": {
"Authorization": "Bearer <your-token>"
},
"tools": [
"issues",
"projects",
"users"
]
}
}
```
Continue.dev (`continue.json`):
```json
{
"mcp": {
"servers": [
{
"name": "youtrack",
"command": "node",
"args": ["/abs/youtrack-mcp/dist/index.js"],
"env": {
"YOUTRACK_URL": "https://your-instance.youtrack.cloud",
"YOUTRACK_TOKEN": "token"
}
}
]
}
}
```
Cline / Generic:
```json
{
"mcpServers": {
"youtrack": {
"command": "node",
"args": ["/abs/youtrack-mcp/dist/index.js"],
"env": {
"YOUTRACK_URL": "https://your-instance.youtrack.cloud",
"YOUTRACK_TOKEN": "token"
}
}
}
}
```
Zed:
```json
{
"context_servers": {
"youtrack": {
"command": "node",
"args": ["/abs/youtrack-mcp/dist/index.js"],
"env": {
"YOUTRACK_URL": "https://your-instance.youtrack.cloud",
"YOUTRACK_TOKEN": "token"
}
}
}
}
```
Local test:
```bash
YOUTRACK_URL=https://your-instance.youtrack.cloud \
YOUTRACK_TOKEN=token \
node dist/index.js
```
Pitfalls: absolute path, no trailing slash, full token copy, JSON env values are strings.

## Architecture
```
Clients (Claude / VSCode / Continue / Zed)
│ MCP (stdio or SSE)
┌────────▼────────┐
│ Orchestrator │ registry, routing, validation
└────────┬────────┘
│ domain calls
┌────────▼────────┐
│ Domain Clients │ issues / projects / agile / kb / analytics / time
└────────┬────────┘
│ REST
┌────────▼────────┐
│ YouTrack API │
└─────────────────┘
```
Traits: strong typing, graceful degradation, normalized errors, pluggable caching/logging.
---
## Development
```bash
npm install
npm run dev # watch
npm run lint # eslint
npm run type-check # types
npm test # tests
npm run build # dist output
```
Structure: `src/index.ts` (entry), `src/api/domains` (domain clients), `src/tools.ts` (tool registry), `src/utils`, `src/logger.ts`.

## Troubleshooting
### Quick Fixes
| Symptom | Cause | Fix |
|---------|-------|-----|
| 401 Unauthorized | Missing scope / expired token | Regenerate token with required permissions |
| 404 Not Found (double `/api/api`) | URL has `/api` suffix | Remove `/api` from `YOUTRACK_URL` |
| Project not found | Hidden / archived / wrong ID | Use internal ID or verify access |
| Empty analytics | No issues in project | Seed baseline issues |
| SSE disconnects | Proxy idle timeout | Enable keep-alive / tune LB |
| AI wrong field values | Dynamic config failed | Check token permissions, restart server |
| Empty search results | `PROJECT_ID` too restrictive | Remove or update `PROJECT_ID` |
**Configuration Checklist**:
- ✅ Absolute path in MCP client config
- ✅ No trailing slash on `YOUTRACK_URL`
- ✅ **No `/api` suffix** on `YOUTRACK_URL` (server adds automatically)
- ✅ Full token with `perm:` prefix
- ✅ JSON env values are strings
- ✅ Token has required permissions
**Debug Mode**: Use `LOG_LEVEL=debug` for detailed inspection.

## Security & Permissions
Recommended token capabilities: Issues (R/W), Projects (Read), Knowledge Base (R/W), Agile/Sprints (R/W), Time Tracking (if applicable). Store tokens as environment secrets; never commit.
