MolClaw Molecule Visualization

SkillFiles & storage

Render a molecule from a SMILES string or a server-side molecular structure file with the MolClaw MCP tool `visualize_molecule`.

Available today. Use it from your connected AI after setup.

Connect ahel once, and every AI you use reads what you have installed.

Then ask your AI: use the MolClaw Molecule Visualization skill

What this skill tells your AI

The instructions your AI receives, as published by internscience/molclaw in skills/L1_tools/molclaw-visualize-molecule/SKILL.md and read by ahel’s review.

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:

FieldTypeMeaning
inputstringA 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"
  • msg
  • image_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.
