Model Context Protocol Host Implementation

[fadnavismehul]

Hi folks !
Love the work being done on marimo. I am quite excited for this to become the tool of choice for analytics and data science

I think it would be a great addition to enable model context protocol host for marimo. I understand there's already an AI assistant inbuilt in marimo and if it can act as a host, it will let us connect locally running MCP servers.

In my workflow, I primarily use the MCP to connect to the following resources

• Datahub for documentation for my data lake tables
• Previous queries in my local storage to evaluate SQL query logics
• Sequential thinking to help a more step-by-step approach

I'm currently using cursor for its superior UI and workflow and integration with MCP servers. Honestly, if marimo let's me utilise these capabilities, I'd be more than happy to completely switch to a marimo workflow. I really want to because I'm an analyst and cursor isn't purpose built for it.

I've even tried using the vscode extension and running marimo notebooks in cursor. Its workable but not as intuitive as it doesn't edit the notebook directly. I may have missed some things in my setup and would be grateful if someone can guide me in a more effective setup if they have managed to use it.

What setups are people using with Marimo ? I'm coming to realise that an AI integration is a non-negotiable for me. Happy to hear more inputs on this !

Can you maybe list out a few tools, prompts and resource endpoints you'd expect?

Here's a non-exhaustive list:

Tools:

• Add Cell
• Edit Cell
• Delete Cell
• Create Notebook

Prompts:

• enforce marimo rules

Resources:

• variables
• tables
• get notebook source
• get docs for variable
• get table docs / schema

Hi, I don't think I understand the question well
I'm not very familiar with how claude MCP is implemented, I'm talking about the end user experience
Basically, I want to have a similar experience to how cursor's chat interface works. I'm currently building MCP servers on my own which I'm connecting to cursor through their MCP integration. This let's me add any kind of function to the agent mode in cursor.

I'm not a developer so I may be misunderstanding some things here.

I think the list of items you've shared seem like a pretty good starting point !
