Molecular Topology Properties Calculation
SkillMonitoring & opsCompute a comprehensive set of topological descriptors for a list of SMILES strings, returning the Topological Polar Surface Area (TPSA), a series of valence and non-valence molecular connectivity indices (Chi0–Chi4), the Hall–Kier alpha value, and Kappa shape indices (Kappa1–Kappa3) for each input molecule.

How to use tool calculate_mol_topology:
response = await client.session.call_tool(
"calculate_mol_topology",
arguments={
"smiles_list": smiles_list
}
)
result = client.parse_result(response)
metrics = result["metrics"]
