internscience MolClaw Molecule Visualization
Use the live MCP tool visualize_molecule when the task needs a simple molecular
structure image.
This tool produces a depiction only. It does not calculate molecular properties
or protein–ligand interactions. Use interaction_visualizer instead when the
task requires residue-level interaction analysis.
Input
The live schema has one required field:
| Field | Type | Meaning |
|---|---|---|
input |
string | A SMILES string or a server-side .sdf, .smi, .smiles, or .mol path |
For a local molecular file, upload it with the MolClaw file-transfer tool first and pass the returned server-side artifact path. Do not invent a server path.
MCP call
From a SMILES string:
<tool_call>{"tool_name":"visualize_molecule","arguments":{"input":"CCO"}}</tool_call>
From a server-side artifact:
<tool_call>{"tool_name":"visualize_molecule","arguments":{"input":"<artifact:molecule/candidate.sdf>"}}</tool_call>
Output
On success, the result contains:
status: "success"msgimage_path: server-generated PNG path
Treat the returned image as the authoritative artifact. In Drug-Pipe online inference, the raw server path is converted to a canonical artifact reference before it is shown to the model or used in the final answer.
If the tool returns an error, preserve the observation and revise the input; do not claim that an image was created.
