# MCP Server E2E Testing
How to set up and run end-to-end tests involving MCP tool servers.
## Where MCP Config Goes
MCP servers are configured in `.qwen/settings.json` under `mcpServers`. This is
the **only** location that works for E2E testing.
Common mistakes that waste time:
- `.mcp.json` — Claude Code convention, not Qwen Code
- `settings.local.json` — schema validation rejects `mcpServers` here
- `--mcp-config` CLI flag — does not exist
## Setup
The CLI needs a git repo to load project settings. Create a temp directory:
```bash
mkdir -p /tmp/test-dir && cd /tmp/test-dir && git init -q
mkdir -p .qwen
cat > .qwen/settings.json << 'EOF'
{
"mcpServers": {
"my-server": {
"command": "node",
"args": ["/tmp/my-mcp-server.js"],
"trust": true
}
}
}
EOF
```
Run from that directory:
```bash
cd /tmp/test-dir && <qwen> "prompt" \
--approval-mode yolo --output-format json
```
## Writing Test Servers
Use `scripts/mcp-test-server.js` as a template. It's a zero-dependency JSON-RPC
server over stdin/stdout — no npm install needed.
To create a server with custom tools, copy the template and edit the
`TOOL_DEFINITIONS` array and the `handleToolCall` function. Each tool definition
follows the MCP `inputSchema` format (standard JSON Schema).
### Sanity-checking the server
Test the server without the CLI by piping JSON-RPC directly:
```bash
node /tmp/my-mcp-server.js << 'EOF'
{
"jsonrpc": "2.0",
"id": 1,
"method": "initialize",
"params": {
"protocolVersion": "2024-11-05",
"capabilities": {},
"clientInfo": { "name": "test", "version": "1.0" }
}
}
{"jsonrpc":"2.0","method":"notifications/initialized"}
{"jsonrpc":"2.0","id":2,"method":"tools/list","params":{}}
EOF
```
## Verifying the Server Loaded
Check the `type: "system"` init message in JSON output:
```json
"mcp_servers": [{"name": "my-server", "status": "connected"}]
```
If `mcp_servers` is empty:
- You're not running from the directory containing `.qwen/settings.json`
- The directory is not a git repo (`git init` missing)
- The server command/path is wrong (check stderr with `2>&1`)
