nifdi AI
nifdi provides an MCP server for working with nifdi diagrams. This operates within your existing AI setup, so you can benefit from the existing access it has to all your code, data and other context.
The core value of the MCP server comes from its Physics Engine. LLMs are not naturally good at keeping track of the complex geometry needed to precisely maintain a diagram. Nifdi MCP relieves the LLM of this responsibility, freeing it to focus on its core capabilities.
Human-agent collaboration
Section titled “Human-agent collaboration”The best way to edit a diagram depends on the task. For broad-brush actions like creating a new diagram from scratch or making wholesale changes, a textual prompt works well. But when you want to make a small focused change like changing a specific word, visual editing is much faster.
Nifdi MCP makes it easy to combine prompting and visual editing. A typical workflow will be multi-step collaboration between human and machine. For example:
| Step | Mode | Action |
|---|---|---|
| 1 | Prompt | Ask for a new diagram. A diagram is generated and is 90% perfect |
| 2 | Visual Editor | Delete items that the LLM included but you didn’t want |
| 3 | Visual Editor | Adjust styling of one element |
| 4 | Prompt | Ask to apply styling change consistently across the whole diagram |
| 5 | Visual Editor | Drag to resize the diagram to be taller and narrower |
Your agent will be able to open the Visual Editor alongside your chat session. You will see the changes the agent is making in realtime, and you can intervene at any time to make your own changes.
Prompts gives examples of what to ask for, and what nifdi can do for you.
Connect your agent to nifdi MCP
Section titled “Connect your agent to nifdi MCP”Connect to nifdi in the way that makes most sense for your situation:
- If you are non-technical or just trying out nifdi, try the Hosted MCP server. This is a paid service, but you can start with a free trial.
- If you are a developer, you can run Local MCP which lets nifdi read and write diagrams directly in your codebase. This mode also avoids any of your code or data going to nifdi’s servers.
MCP modes in more detail:
| Hosted MCP | Local MCP | |
|---|---|---|
| Ideal for | Anyone | Developers, technical users |
| Works on the web | ✅ Yes | ❎ No |
| Works in local Claude Code / Codex | ✅ Yes | ✅ Yes |
| Where are diagrams stored? | In the cloud | On your local machine |
| Where does nifdi run? | In the cloud | On your local machine |
| Cost | Paid | Free |
Skills
Section titled “Skills”Both kinds of MCP work with the nifdi skills plugin. It bundles the MCP server together with guidance that teaches the agent how to build and review clearer diagrams.
