##  Quick Start

Add the following to your MCP client configuration:

```json
{
  "mcpServers": {
    "limit-order": {
      "command": "npx",
      "args": ["-y", "@dbotx/limit-order-mcp-server@latest"],
      "env": {
        "DBOT_API_KEY": "your-api-key",
        "DBOT_WALLET_ID": "your-wallet-id"
      }
    }
  }
}
```
**Get your api-key and wallet-id at [www.dbotx.com](https://www.dbotx.com)**

## 📚 Typical Scenarios

- **Sell High**:
  - "Help me sell 50% of my position in token {{token_address}} on Solana when the price is above $100."
- **Buy Low**:
  - "Help me buy 1 of token {{token_address}} on Solana when the price is below $0.0001."
- **Modify Limit Order**:
  - "Help me change the trigger price of the limit order to $20 and turn off anti-sandwich mode."
- **Query Limit Orders**:
  - "Help me check all my limit orders."
- **Manage Limit Orders**:
  - "Help me disable this limit order."
  - "Help me re-enable this limit order."
  - "Help me delete this limit order."


## 🌱 Environment Variables

Here are the environment variables explained:

### Required Environment Variables
- `DBOT_API_KEY`: DBot API key (required)
- `DBOT_WALLET_ID`: Default wallet ID (required)

### Optional Default Parameter Configuration
- You can change the configuration according to the examples. If not changed, the default configuration will be used.
- The default configuration can be obtained by talking to the LLM, for example, "Tell me the default configuration for the limit order tool."
- All environment variable defaults can be overridden during the conversation. For example, if the system's default is to enable anti-sandwich mode, you can request to override it by saying, "Create a limit order..., please disable anti-sandwich mode."

#### Basic Configuration
- `DBOT_CHAIN`: Default chain type (solana/ethereum/base/bsc/tron)
- `DBOT_CUSTOM_FEE_AND_TIP`: Whether to use custom fees (true/false)
- `DBOT_PRIORITY_FEE`: Priority fee, e.g., "0.0001"
- `DBOT_GAS_FEE_DELTA`: Gas fee increment, e.g., 5
- `DBOT_MAX_FEE_PER_GAS`: Maximum gas fee, e.g., 100
- `DBOT_JITO_ENABLED`: Whether to enable anti-sandwich mode (true/false)
- `DBOT_JITO_TIP`: Anti-sandwich tip, e.g., 0.001
- `DBOT_MAX_SLIPPAGE`: Maximum slippage (0.00-1.00), e.g., 0.1
- `DBOT_CONCURRENT_NODES`: Number of concurrent nodes (1-3), e.g., 2
- `DBOT_RETRIES`: Number of retries (0-10), e.g., 1

**Example:**

```json
{
  "env": {
    "DBOT_API_KEY": "your-api-key",

    "DBOT_CONCURRENT_NODES": "2",
    "DBOT_RETRIES": "1"
  }
}
```

#### Limit Order Configuration
- `DBOT_EXPIRE_DELTA`: Task validity duration (in milliseconds), e.g., 432000000
- `DBOT_EXPIRE_EXECUTE`: Whether to execute at market price upon task expiration (true/false)
- `DBOT_USE_MID_PRICE`: Whether to use anti-spike mode (true/false)

**Example:**

```json

## ⚠️ Notes

1.  `walletId` is optional; `DBOT_WALLET_ID` is used if not provided.
2.  Prices are in USD; use reasonable precision.
3.  The default task validity is 432,000,000 milliseconds (5 days).
4.  Trigger direction: `up` triggers on price increase, `down` triggers on price decrease.
5.  Anti-spike mode can prevent false triggers from momentary fluctuations.
6.  It's configurable whether to force execution at market price upon expiration.
