Notes Server MCP Server: Managing Notes with Persistent Storage

Overview: What is Notes Server MCP Server?

The Notes Server is an implementation of the Model Context Protocol (MCP) designed to manage notes with persistent storage. This server provides a structured way for AI applications, such as Claude Desktop, Continue, and Cursor, to interact with data through a standardized protocol. By offering features like note creation, reading, updating, and deletion, along with persistent JSON storage and timestamping, this MCP server enhances the interoperability of various tools within an AI application ecosystem.

🔧 Core Features & MCP Capabilities

The Notes Server supports several core functionalities that enhance its MCP capabilities:

CRUD Operations: The server can create, read, update, and delete notes efficiently.
Persistent Storage: Notes are stored in notes_storage.json with timestamps for creation and modifications.
Note Summarization via Prompts: An integrated prompt generation feature allows for summarizing notes, ensuring they are formatted suitably for language models.
Resource Access: Notes can be accessed using the note:// URI scheme, facilitating resource-based access.

These features allow users to manage notes in a structured manner while maintaining compatibility with various MCP clients.

⚙️ MCP Architecture & Protocol Implementation

The Notes Server architecture is designed to adhere strictly to the Model Context Protocol (MCP), ensuring seamless integration with other compliant applications. The server structure includes key components such as:

Storage Module: Manages note persistence using JSON files.
Resources Module: Handles URI access for notes.
Prompts Module: Generates prompts for summarization tasks.

The server's protocol flow involves an MCP client initiating requests, which are then processed by the Notes Server and responded to appropriately. This streamlined process guarantees minimal latency and optimal performance.

🚀 Getting Started with Installation

To set up and run the Notes Server, follow these instructions:

Install via Smithery:

npx -y @smithery/cli install notes --client claude

Manual Installation (Python 3.10+ required):

python -m venv .venv
source .venv/bin/activate # On Unix/MacOS
.venv\Scripts\activate # On Windows
pip install MCP

💡 Key Use Cases in AI Workflows

Use Case 1: Collaboration and Note Sharing

In a collaborative project, developers use the Notes Server to share insights and document progress. For example, multiple team members can add notes, update them as needed, and even access these notes using note:// URIs.

# Create a new note
await client.call_tool("add-note", {
    "name": "example",
    "content": "This is a test note"
})

# Modify an existing note
await client.call_tool("update-note", {
    "name": "example",
    "content": "Updated content"
})

# Delete the note if no longer needed
await client.call_tool("delete-note", {
    "name": "example"
})

Use Case 2: Data Management for Research Projects

Researchers can leverage the Notes Server to catalog and curate data sources. By using notes as a metadata repository, they can track details about each piece of data, including its origin and relevance.

For instance:

# List all stored notes
await client.call_tool("list-all-notes")

# Create a structured summary of notes
await client.call_tool("summarize-notes", {
    "note_names": ["example1", "example2"]
})
