MRSimulator MCP co.huggingface.paonai/mrsimulator Simulate a 2D multi-quantum MAS (MQ-VAS) correlation spectrum for SEVERAL quadrupolar sites at once - generalizes simulate_mqmas_spectrum beyond a single site. This matters because resolving overlapping quadrupolar sites via 2D correlation is usually the actual point of running MQMAS in the first place (e.g. the three crystallographically distinct sites of RbNO3, or several aluminosilicate sites) - a single-site-only tool missed that. 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_dim1_hz,broadening_dim2_hz,center_dim1_ppm,center_dim2_ppm,isotope,magnetic_flux_density_T,quantum_order,shear_matrix_json,sites_json,spectral_width_dim1_hz,spectral_width_dim2_hz | Not stated |
