laplaci, a 3D graphing calculator with an MCP control panel

Field notes

The interface exposes separate controls for scalar fields, surfaces, vector fields, and approximation, along with bounds, precision, isosurface steps, and particle-flow parameters. Its MCP Setup panel provides a copyable configuration and states that external agents can write expressions or tune render settings in the current tab; Chrome may request permission when the panel is enabled. The page also includes saved-state and diagnostics controls.
