🎉Custom Instructions Per Server! v3.5.0

[ravitemer]

Why?

You know that feeling when you're using MCP servers and keep repeating the same things to your LLM assistant? Maybe it's those Discord channel IDs you copy-paste all the time, or explaining how to properly test your web app.

MCPHub.nvim now has a simple solution: custom instructions for each server. Just write down those details once, and they'll automatically be included every time you chat. Even better, you can guide your LLM on exactly how you want it to use the server's tools - like reminding it to always check console logs after page navigation, or making sure it includes the right parameters.

Some Real-World Use Cases

1. Discord Integration Made Easy

If you're using a Discord MCP server, you probably find yourself repeatedly copying channel IDs for the send_message tool. With custom instructions, you can now store these details permanently:

Here are the important channels for my Discord server: General Chat (1223456), Announcements (121345), Support (23402094). When sending messages, default to General Chat unless specified otherwise. For announcements, always include our server emoji :rocket:.

2. Automated Testing Guidelines

When working with a Playwright/Puppeteer MCP server for web testing, custom instructions can enforce consistent testing practices:

Always fetch the console logs resource after navigation operations. Test our app at http://localhost:5173. Before interacting with forms, wait for the loading spinner to disappear (selector: .loading-spinner). Any 404 or 500 errors should be reported with a screenshot. Use desktop viewport (1920x1080) unless mobile testing is specifically requested.

How to Use

1. Open MCPHub UI (:MCPHub)
2. Select a server
3. Click to add or edit instructions
