REI Crypto MCP Server

Instructions

Same as /pools but it also includes a new parameter `pool_old` which usually contains pool address.

Implementation Reference

• defillama_server.py:344-351 (handler)

  The main handler function for the 'get_yield_pools_old' tool. It is decorated with @mcp.tool(), which also serves as the registration mechanism in FastMCP. The function makes an API request to the DefiLlama /yields/poolsOld endpoint and returns the result as a string.

  @mcp.tool()
  async def get_yield_pools_old() -> str:
      """GET /yields/poolsOld
      
      Same as /pools but it also includes a new parameter `pool_old` which usually contains pool address.
      """
      result = await make_request('GET', '/yields/poolsOld')
      return str(result)

• defillama_server.py:30-38 (helper)

  Shared helper function used by get_yield_pools_old (and other tools) to perform HTTP requests to the DefiLlama API.

  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)}"
