# MCP Server Testing

# Testing Tools

## Using MCP Inspector

The [MCP Inspector](https://github.com/modelcontextprotocol/inspector) is ideal
for testing tools:

```bash
npx @modelcontextprotocol/inspector
```

1. Set **Transport Type** to "Streamable HTTP"
2. Set **URL** to your MCP endpoint (for example,
   `https://your-gateway.zuplo.dev/mcp`)
3. Connect and test your tools interactively

## Using cURL

Test individual tools directly:

```bash
# List available tools
curl https://your-gateway.zuplo.dev/mcp \
  -X POST \
  -H 'Content-Type: application/json' \
  -d '{
    "jsonrpc": "2.0",
    "id": "0",
    "method": "tools/list"
  }'

# Call a specific tool
curl https://your-gateway.zuplo.dev/mcp \
  -X POST \
  -H 'Content-Type: application/json' \
  -d '{
    "jsonrpc": "2.0",
    "id": "1",
    "method": "tools/call",
    "params": {
      "name": "addNumbers",
      "arguments": {
        "a": 5,
        "b": 3
      }
    }
  }'
```
