Getting Started 🏁

Ready to dive into the crypto price pool? Here’s how to get this baby running:

Prerequisites

- Deno: You’ll need Deno installed because we’re fancy and modern. Grab it here. - Bitget API Access: No API key needed – we’re hitting the public endpoint like champs! But if you’ve got a custom BGURL, set it as an environment variable.

Installation

1. Clone this repo like it’s hot:

   git clone https://github.com/pwh-pwh/coin-mcp-server.git
   cd coin-mcp-server
   

2. Install dependencies (Deno handles this automagically via imports!).

Running the Server

Fire it up with:

deno run --allow-net --allow-env --allow-read main.ts

or

deno run --allow-net --allow-env --allow-read https://deno.land/x/coin_mcp_server/main.ts

- --allow-net: Lets us talk to Bitget’s API.
- --allow-env: Grabs your BGURL env variable if you’ve set one.

The server will start in stdio mode, ready to serve up prices like a crypto vending machine! 🍔

3. Support installation-free, directly deploy to deno, fork this project, log in dash.deno.com, set the environment variable StartType=sse to use the domain name provided by deno to connect in sse mode

Configuration

config.json

{

  "mcpServers": {

    "coin-mcp": {

      "command": "deno",

      "args": [

        "run",

        "--allow-net",

        "--allow-read",

        "--allow-env",

        "https://deno.land/x/coin_mcp_server/main.ts"

      ]

    }

  }

}

Usage Example 🎮

Here’s how you’d call getTokenPrice:

{

  "tool": "getTokenPrice",

  "parameters": {

    "token": "BGB"

  }

}

Response:

"42.069"  // The latest BGB/USDT price (not a real price, just vibes!)

If the token doesn’t exist or the API hiccups, it’ll throw an error with a cheeky log to remind you it tried its best. 😅

Code Sneak Peek 👀

Here’s the magic behind the curtain:
- FastMCP: Spins up the server with a cool name and version.
- Zod: Keeps your token parameter in check.
- Bitget API: Fetches ticker data from https://api.bitget.com/api/v2/spot/market/tickers.

The getBitgetPrice function is the MVP, grabbing that sweet lastPr (last price) from the response. Check the logs for price updates or error comedy gold! 😂

---

Environment Variables 🌍

- BGURL: Custom Bitget API base URL (defaults to https://api.bitget.com if not set). Set it like:

  export BGURL="https://your-custom-bitget-url.com"

  

---

Troubleshooting 🛠️

- “HTTP error! status: 404”: Double-check your token symbol. BGBUSDT isn’t the same as BGB!
- “Network error”: Make sure you’ve got internet and Deno’s --allow-net flag.
- Still stuck?: Yell into the void (or open an issue). We’ll figure it out together! 🙌

Why This Exists 🎉

Because who doesn’t want to know the price of their crypto stash in real-time? Whether you’re a trader, a HODLer, or just crypto-curious, this server’s got your back. Plus, it’s a fun way to flex some Deno skills and play with APIs. 😎
