REI Crypto MCP Server

Instructions

Simplified endpoint to get current TVL of a protocol.

Parameters:
    protocol: protocol slug (e.g., 'uniswap')

Implementation Reference

• defillama_server.py:115-125 (handler)

  The handler function for the 'get_protocol_tvl' tool. It is automatically registered as an MCP tool via the @mcp.tool() decorator. The function signature and docstring define the input schema (protocol: str) and output (str representing JSON response). It fetches the current TVL from DefiLlama API using the make_request helper.

  @mcp.tool()
  async def get_protocol_tvl(protocol: str) -> str:
      """GET /api/tvl/{protocol}
      
      Simplified endpoint to get current TVL of a protocol.
      
      Parameters:
          protocol: protocol slug (e.g., 'uniswap')
      """
      result = await make_request('GET', f'/api/tvl/{protocol}')
      return str(result)

• defillama_server.py:30-38 (helper)

  Helper function used by get_protocol_tvl (and other tools) to make HTTP requests to the DefiLlama Pro API, handling errors and returning JSON or error string.

  async def make_request(method: str, endpoint: str, params: Optional[Dict[str, Any]] = None) -> Any:
      """Make a request to the DefiLlama API."""
      try:
          response = await client.request(method, endpoint, params=params)
          response.raise_for_status()
          return response.json()
      except Exception as e:
          return f"Error: {str(e)}"

• defillama_server.py:115-115 (registration)
