Trying to find a tool/method to batch generate materials from raymarched shaders/shadertoys

I am an artist that builds things in VRchat.

Right now i am working with a library of around 14,000 raymarched shaders/shadertoys, and as you can imagine, making materials from those by hand would be very tedious.

As these are shadertoys, there is no 2d texture in use, its all shadermath.

Ive seen code and tools to batch generate materials from a 2D image, but none of them seem to be designed to explicitly generate materials from only a shader.

Id like some advice and direction for this if anyone has ideas.
