headers={"SCP-HUB-API-KEY": "sk-a0033dde-b3cd-413b-adbe-980bc78d6126"}
)
self._stack = AsyncExitStack()
await self._stack.__aenter__()
self.read, self.write, self.get_session_id = await self._stack.enter_async_context(self.transport)

print("✓ already disconnect")
except Exception as e:

def parse_result(self, result):
try:
if hasattr(result, 'content') and result.content:
content = result.content[0]
if hasattr(content, 'text'):

2. Protein Sequence Valid Check
The description of tool calculate_dleps_score.
Enter a list of candidate small molecules. Based on the input disease name, identify upregulated and downregulated genes associated with the disease state, and predict a reversal score for each small molecule. Generally, a score above 0.2 indicates effectiveness, with higher scores being better.
Args:
smiles_list (List[str]): List of input SMILES strings, (e.g., ["N[C@@H](Cc1ccc(O)cc1)C(=O)O", "CC(C)C1=CC=CC=C1"])
disease_name (str): Supportes diseases, e.g., "Aging", "Gout", "Pulmonary fibrosis", "Non-alcoholic fatty liver disease", "Obesity"
Return:
status (str): success/error
msg (str): message
pred_scores (List[dict]): List of dict, each containing the keys 'smiles' and 'cs_score'.
--smiles (str): A SMILES string of smiles_list
--cs_score (float): Predicted reverse score
How to use tool calculate_dleps_score :
client = DrugSDAClient("https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool")
if not await client.connect():
print("connection failed")
return
response = await client.session.call_tool(
"calculate_dleps_score",
arguments={
"smiles_list": smiles_list,
"disease_name": disease_name
}
)
result = client.parse_result(response)
pred_scores = result["pred_scores"]
await client.disconnect()
