It is decorated with @mcp.tool(), which registers it, and implements the tool logic by calling the DefiLlama API endpoint /yields/chart/{pool} to retrieve historical APY and TVL for a given pool ID.@mcp.tool() async def get_yield_chart(pool: str) -> str: """GET /yields/chart/{pool} Get historical APY and TVL of a pool. Parameters: pool: pool id (can be retrieved from /pools) """ result = await make_request('GET', f'/yields/chart/{pool}') return str(result)
- defillama_server.py:30-38 (helper)Shared utility function used by the get_yield_chart handler (and all other tools) to perform HTTP requests to the DefiLlama Pro 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)}"
