nifdi

nifdi draws block-and-connector diagrams: boxes, text and icons joined by arrows. Connect it to Claude and ask for a diagram in plain language, as you would a colleague:

• "Draw the architecture of this repository, grouping services by deployment."
• "Make a flowchart of the sign-up process described in this document."
• "Recreate the diagram in this screenshot."
• "Add a queue between the API and the worker, and label the arrow retries."
• "Make every database the same colour, and line the services up in a row."

nifdi works out the layout. Claude says what goes where, and nifdi sizes and places everything, routes the arrows around the boxes, and keeps labels attached to what they describe when anything moves. Claude is freed from tracking geometry and can focus on the content of the diagram.

What you get:

• Diagrams stored in your nifdi account, open in the nifdi visual editor and to every agent you connect.
• A live editor link for any diagram. You see Claude's changes as they happen, and Claude builds on yours, so you can mix asking and editing, using whichever is quicker.
• Rendered images in the chat, so Claude checks a diagram's appearance before calling it finished.
• Icon libraries for use in your diagrams, searchable by name.
• One shared change history per diagram. Every change records who made it, and either of you can undo or redo any change, including the other's.

Tools cover creating and listing diagrams; inserting, moving, resizing, aligning, arranging and connecting blocks; setting text and styles; searching icons; rendering; and reading history, undo and redo.

nifdi Hosted MCP is a paid feature. Sign in with your nifdi account when you connect; a free trial is available. Each connected agent is listed in your account settings, where you can disconnect it at any time. Developers who prefer diagrams as files in their own repository can use the free local nifdi MCP server instead.
