MCP Server Opensearch

Provides a simple note storage MCP server with note management and summarization tools.

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "gowtham3105-mcp_server_opensearch": {
      "command": "uv",
      "args": [
        "--directory",
        "/Users/gowtham/Gowtham/Projects/mcp-server-opensearch",
        "run",
        "mcp-server-opensearch"
      ]
    }
  }
}

You have an MCP server named Opensearch that stores simple notes and exposes a small set of capabilities you can use from any MCP client. It supports creating notes, listing their metadata, and generating summarized prompts across all stored notes. This makes it easy to build lightweight note-centric workflows and integrations, without digging into raw data every time.

How to use

Interact with the server through an MCP client to manage notes and run prompts. You can add new notes with the add-note tool, retrieve and view note information via the note:// scheme, and run prompts like summarize-notes to generate a consolidated summary of all stored notes. The server updates clients about changes to resources so you stay in sync as you add or modify notes.

Common usage patterns include:

Add a new note with a name and content using the add-note tool
View or access individual notes using their note:// URI (each note has a name, description, and text/plain mimetype)
Run the summarize-notes prompt to generate a consolidated summary of all notes, with an optional style parameter to control detail level (brief or detailed)

How to install

Prerequisites you need before starting you MCP server are in place: ensure you have access to the MCP runtime tooling used to manage and run servers (the uv/uvx flow used here). These steps assume you will run the server from its project directory and use the MCP tooling to build and execute it.

Step 1: Prepare your environment

Step 2: Sync dependencies and build

Step 3: Run the server

uv sync
uv build
uv run mcp-server-opensearch

Configuration and startup examples

The server can be started using runtime configurations shown in code blocks. These examples illustrate how the MCP runtime can launch the server in development and published modes.

{
  "mcpServers": {
    "mcp-server-opensearch": {
      "command": "uv",
      "args": [
        "--directory",
        "/Users/gowtham/Gowtham/Projects/mcp-server-opensearch",
        "run",
        "mcp-server-opensearch"
      ]
    }
  }
}

{
  "mcpServers": {
    "mcp-server-opensearch": {
      "command": "uvx",
      "args": [
        "mcp-server-opensearch"
      ]
    }
  }
}

Notes about tools and prompts

Available prompts and tools are designed to be simple to use from your MCP client. You use the summarize-notes prompt to create summaries of all stored notes. It accepts an optional style argument to control detail level, such as brief or detailed. The add-note tool lets you add a new note by supplying a name and the content as required strings, updating the server state and notifying clients of resource changes.

Troubleshooting and tips

If you run into debugging challenges because the MCP server operates over stdio, consider using the MCP Inspector for a richer debugging experience. You can launch the Inspector with MCP-specific commands to view a debugging URL in your browser.

Available tools

summarize-notes

A prompt that creates summaries of all stored notes. It accepts an optional style argument to control detail level (brief/detailed) and generates a prompt by combining all current notes with the preferred style.

add-note

A tool to add a new note by providing a name and content as required strings. It updates the server state and notifies clients of resource changes.
