Eraser

Connects Claude to Eraser's diagramming platform so you can generate and modify technical diagrams directly from conversation. You can create architecture diagrams, flowcharts, sequence diagrams, and entity relationship diagrams without leaving your chat session, then edit them iteratively as your design evolves. Useful when you're sketching out system designs, documenting APIs, or prototyping data models and want to instantly visualize what you're discussing. The server talks to Eraser's hosted API, so you'll need an Eraser account. Saves the context switching between ideation and diagram tools when you're working through technical problems that benefit from visual representation.
