Show HN: MCP Jetpack – The easiest way to get started with MCP in Cursor

https://mcpjetpack.com
17•gsundeep•6mo ago
My friends and I built MCP Jetpack which makes it really easy to start using MCP. It’s an MCP server that automatically finds and executes the right tools needed to accomplish your task without having to manage MCP servers for each service (GitHub, Linear, Atlassian, Notion etc.). Once you add it to Cursor (or any other AI app with MCP support), Cursor instantly gets access to a growing library of remote MCP servers without any extra setup. For services that require authentication, you will be asked to login the first time you ask your AI to interact with that service.

Two problems we are trying to solve:

Friction - Normally if you want to give Cursor access to GitHub, you have to install the right MCP server and login before you can use GitHub with Cursor’s chat. With MCP Jetpack, you can ask Cursor to list your GitHub issues, and it will automatically execute the right tool behind the scenes to accomplish your task. For services that require authentication, you will be asked to login the first time you interact with the service. However, it all happens within the Cursor chat so you never have to context switch and fiddle with Cursor’s settings.

Tool Limits - Cursor warns you if you have more than 50 MCP tools installed as it says having more will degrade performance. However, just installing the GitHub MCP server itself adds 74 MCP tools. With MCP Jetpack, you get access to GitHub, Atlassian and 15 other services with just two tools: “FindTool” and “ExecTool”.

Here are the 17 services we support today: GitHub, Atlassian, Canva, Linear, Notion, Intercom, Monday.com, Neon, PayPal, Hugging Face, Sentry, Square, Webflow, Wix, Cloudflare Docs, Cloudflare AI Gateway, Cloudflare Workers Bindings.

We’ll continue to add more services as companies launch remote MCP servers. If yours isn’t listed and you’d like it to be added, please email us at team@mcpjetpack.com.

MCP Jetpack is in alpha so please let us know if you run into any problems or have any feedback - thanks!

It seems like a pretty simple rule in 2025: if your AI-related devtool project is not an open source, doesn't allow to self-host, and is not a tier-1 (your own models, or similar level of "secret sauce") -> it will be replicated within a week or so. And I like this new realm.
gsundeep•6mo ago
We are thinking of open sourcing it, the current codebase requires Cloudflare Workers so it will take some changes to make it more generic. Thank you for the feedback!
eagleinparadise•6mo ago
Isn't the issue that you all can possibly retain any data since you are acting as an intermediary? And your code is not open source?
willahmad•6mo ago
Would you prefer a local only tool?

As a privacy conscious person, I am developing a desktop/local only app and collecting feedback from beta testers. I would appreciate if you can participate as a beta tester and share your feedback.

At the moment, app is only available for MacOS, and in the process of security audit (not SOC-2 yet, but we will get there). I am planning to sell a license.

Please let me know how to contact you, if you prefer to send email here is my disposable email: kzphefll8@mozmail.com (to prevent spam emails, not sharing my original email)

Currently we are only recording which tools were requested by the MCP client. We don't store details of the executed tool, neither the arguments nor the response. Currently we are not open source but we are considering that. Thanks for the feedback!
jonplackett•6mo ago
Maybe I’m just getting old but having lots of MCP servers happening automatically feels scary.
gsundeep•6mo ago
Agreed, I think adding guardrails to this would be really useful to ensure the AI only has limited permissions to these services (or asking for some sort of confirmation before making potentially dangerous tool calls).
tehryanx•6mo ago
It really concerns me that this is an afterthought rather than MVP table stakes.
jonplackett•6mo ago
Imagine the show HN post of:

HEY GUYS. I just made an amazing NPM package - it just adds in whatever other packages you need depending on what it looks up randomly on the internet and runs them.

Actually now a read this it does sound kinda similar to how NPM works…

Creating your own MCP server in Cursor requires <50 lines of code for the base (https://blog.toolkami.com/toolkami-shttp-server/)
