weather-server MCP Server

A Model Context Protocol server

This is a TypeScript-based MCP server that implements a simple notes system. It demonstrates core MCP concepts by providing:

• Resources representing text notes with URIs and metadata
• Tools for creating new notes
• Prompts for generating summaries of notes

Features

Resources

• List and access notes via note:// URIs
• Each note has a title, content and metadata
• Plain text mime type for simple content access

Tools

• create_note - Create new text notes
  • Takes title and content as required parameters
  • Stores note in server state

Prompts

• summarize_notes - Generate a summary of all stored notes
  • Includes all note contents as embedded resources
  • Returns structured prompt for LLM summarization

Development

Install dependencies:

npm install

Build the server:

npm run build

For development with auto-rebuild:

npm run watch

Installation

Load up a Datastax collection with the monster data.

Get the Datastax Astra DB API endpoint and token from the Astra DB UI.

Run pnpm install to install the dependencies.

Run pnpm run build to build the server.

Edit the claude_desktop_config.json file to add the server config:

On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json On Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "monster-server": {
      "name": "monster-server",
      "command": "[path to node]",
      "args": ["[path to this repo]/build/index.js"],
      "env": {
        "ASTRA_DB_API_ENDPOINT": "https://[dbname].apps.astra.datastax.com",
        "ASTRA_DB_APPLICATION_TOKEN": "[token]"
      }
    }
  }
}

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser.

You will need to set the ASTRA_DB_API_ENDPOINT and ASTRA_DB_APPLICATION_TOKEN environment variables in the inspector UI.
