MRSimulator MCP co.huggingface.paonai/mrsimulator Simulate a multi-site NMR spectrum (e.g. several crystallographic sites of a published compound), with relative abundances. Each site may include chemical-shift anisotropy, quadrupolar coupling, or both, plus the relative orientation between the two tensors if a site has both (see simulate_powder_pattern for how much that can matter). IMPORTANT for the calling agent: this tool's result includes a text line reading "Image URL: <url>" alongside the image data. Take that url and relay it in your reply as markdown image syntax,  - do not just mention the url as plain text or describe the image instead. Some clients only display images embedded this way in the visible reply; images left inside the raw tool result are not shown to the user on those clients. | broadening_hz,isotope,magnetic_flux_density_T,rotor_angle_deg,rotor_frequency_hz,sites_json,spectral_width_hz,spectrum_type | Not stated |
