## Tools (as reported by the server, not verified)

- `encode\_graph\_url`: Build an equation.io graph link, validating every row with the app's parser. Pass the COMPLETE graph in "equations": a flat array of strings, one equation or definition per string, in display order — when editing an existing graph \(see decode\_graph\_url\), include unchanged rows too. Rows can be: equa
- `decode\_graph\_url`: Decode an equation.io link \(either the \#-fragment form or the /g/ share form\) into its list of equation rows, so you can edit them and build a new link with encode\_graph\_url. The rows use the equation.io syntax documented in the "syntax" MCP resource \(also at https://equation.io/llms.txt\).
- `show\_graph`: Display an interactive equation.io graph inside the conversation, with editable equations, sliders, pan/zoom, and 3D rotation. Use when the user asks to see or explore a graph. Pass the COMPLETE graph as "equations", one equation or definition per string, preserving unchanged rows when editing. For
