Hi Developers, I want to know how to create Model context protocol with existing LLM ,Basically I want to read , create , write Files inside my Local folder using LLM prompting

hey, this is basically what motivated me to build https://github.com/valtors/relay

you don't need to write a server from scratch. easiest path:

1. install the official filesystem MCP server. add this to your Claude / Cursor config:

{
  "mcpServers": {
    "files": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-filesystem", "/path/to/your/folder"]
    }
  }
}

replace /path/to/your/folder with the folder you want the LLM to access. on Windows use double backslashes like C:\\Users\\YourName\\Documents.

2. restart your editor. you should see file tools available.

3. then just prompt naturally - "read my notes.txt" or "create a file called ideas.md with..."

a few gotchas:

• the path must be absolute, relative paths often fail silently
• if you want multiple folders, add multiple server entries with different names
• the LLM can only access the folder you gave it, not your whole drive

if you want more than files (images, pdfs, web fetch, etc) in one server instead of installing five different ones, that's what Relay tries to solve (npx userelay). but start with the filesystem server, it covers 90% of use cases.

hope that helps
