Model Context Protocol Server

---

This repository is structured as a monorepo containing three standalone MCP (Model Context Protocol) server implementations mcp-basic, mcp-cloudflare, and mcp-mongo each built for different execution environments and use-cases, These servers can integrate with AI models (e.g., Claude AI) and can be tested using commands and prompts.

⚙ Installation & Local Setup

Follow the steps below to run the MCP Basic server locally:

1. ✅ Clone the repository:

git clone https://github.com/PAIshanMadusha/model-context-protocol-server.git

2. ✅ Navigate to the Basic MCP server:

cd model-context-protocol-server/mcp-basic

3. ✅ Install dependencies:

npm install

4. ✅ Build the application:

npm run build

---

🧪 Run & Test

Below are multiple ways to test this MCP server using Inspector, Cursor, and Claude.

5. 🌐 Test using MCP Inspector (recommended):

npx @modelcontextprotocol/inspector

* After launching: Open the Inspector UI (auto-opens in browser), Click Add MCP Server & Use the following configuration:

Command: node Arguments: build/index.js

* Then click Connect to start testing tools.

6. 🌐 Test using Cursor IDE:

* Open Cursor: Settings → Tools → MCP and add:

"mcpServers": {
  "model-context-protocol-basic": {
    "command": "node",
    "args": ["C:/path/to/model-context-protocol-server/mcp-basic/build/index.js"] // replace with your actual path
  }
}

* Now you can use the tools directly inside Cursor's AI chats.

7. 🌐 Test with Claude AI (Desktop):

* Open Claude: **Settings → Developers → Edit config, Add:

"mcpServers": {
  "model-context-protocol-basic": {
    "command": "node",
    "args": ["C:/path/to/model-context-protocol-server/mcp-basic/build/index.js"] // replace with your actual path
  }
}

* Restart Claude & Start chatting and access the MCP Tools panel.

🌐 2) MCP Cloudflare Worker: Features & Installation

🔥 Features

This MCP server implementation runs entirely on Cloudflare Workers, offering task & todo management through HTTP-based MCP transport.

1. 🔧 Supported Tools: Task Management

Tool Name	Function	Description
create-task	Create Task	Creates a new task with title + details and stores it in KV backend.
list-tasks	List Tasks	Retrieves the full list of stored tasks with metadata and timestamps.
get-task-by-id	Retrieve Task	Fetches details of a specific task using its unique ID.
update-task-by-id	Update Task	Updates task fields such as name, status, or description.
delete-task-by-id	Delete Task	Permanently removes a task from storage using its ID.

2. 🔧 Supported Tools: Todo Management

Tool Name	Function	Description
create-todo	Add Todo	Creates a new todo item and associates it with a task (parent task required).
list-todos	List Todos	Retrieves all todo items under a specific task, grouped by task ID.
get-todo-by-id	Retrieve Todo	Fetches detailed information for a todo item using its ID.
update-todo-by-id	Update Todo	Updates todo fields such as text, checklist status, or completion progress.
delete-todo-by-id	Delete Todo	Deletes a specific todo item from its linked task.

3. 🗂 API Endpoints

* 🌍 Example Deployment: (Replace with your own deployment URL)

https://mcp-cloudflare.paishanmadusha.workers.dev

Route	Purpose
/mcp	REST-based MCP transport
/sse	Server-Sent-Events MCP streaming

⚠ Note: Cloudflare free-tier accounts do not allow creation of Worker KV storage, you can still test without storage using mcp-mongo (same tools, MongoDB backend).

---

⚙ Installation & Local Setup

Follow the steps below to run and deploy the Cloudflare MCP server:

1. ✅ Clone Repository:

git clone https://github.com/PAIshanMadusha/model-context-protocol-server.git

2. ✅ Navigate to Cloudflare MCP Server:

cd model-context-protocol-server/mcp-cloudflare

3. ✅ Install Dependencies:

npm install

4. ✅ Add Worker KV Binding:

* Create a KV namespace in Cloudflare → Storage & Database → Workers KV and enter it in wrangler.toml:

"kv_namespaces": [
		{
			"binding": "MCP_CLOUDFLARE_STORE",
			"id": "b98f377e26184191968cf4a2ad014df5", # replace with yours
			"remote": true
		}
	]

5. ✅ Deploy to Cloudflare:

wrangler deploy

🧪 Run & Test

Below are multiple ways to test this MCP server using Inspector, Cursor, and Claude.

6. 🌐 Test with MCP Inspector:

npx @modelcontextprotocol/inspector

* After launching: Open the Inspector UI (auto-opens in browser), Click Add MCP Server & Use the following configuration:

Command: node Arguments: https://mcp-cloudflare.paishanmadusha.workers.dev/mcp

* Then click Connect to start testing tools.

7. 🌐 Test using Cursor IDE:
