mcp_server_opensearch

This MCP server provides a simple note storage system with a custom note:// URI scheme for accessing individual notes. Each note has a name, description, and a text/plain payload. The server exposes a single tool named add-note, which lets clients add a new note by specifying a required name and content. It also offers a summarize-notes prompt that generates a summary of all stored notes, with an optional style parameter to control the level of detail (brief or detailed). The server notifies connected clients of resource changes when notes are added, enabling real-time awareness of state changes. To interact with the server, you’ll typically run it through the MCP runtime (via uv/uvx) and then issue tool invocations and prompt requests through your MCP client or inspector tooling.

Usage flow: start the server, then use the add-note tool to create notes by providing {"name": "Note title", "content": "Note body text"}. After accumulating notes, invoke the summarize-notes prompt with an optional style argument (e.g., {"style": "detailed"}) to obtain a consolidated summary of all notes. The server’s note:// scheme allows clients to reference individual notes directly, facilitating integration with other MCP components or editors.

Prerequisites

• Python 3.8+ installed on your system
• Access to the MCP runtime tooling (uv/uvx) as described in the repository docs

Installation steps

1. Install the MCP runtime (uv/uvx) if you haven’t already. The project often uses a PyPI-based distribution or a package manager depending on your environment. Example (adjust if your setup differs):

   • Install Python and ensure python3 and pip are in PATH
   • Install the MCP runtime tooling (assume uv is the CLI wrapper): pip install uv # or follow the project’s recommended installation method

2. Install project dependencies and prepare the package for development/build:

   uv sync

3. Build/local distributions for the server package (if the project requires it):

   uv build

4. Run or test locally (development mode) using the provided server entry:

   uv run mcp-server-opensearch

5. Verify the server starts and is reachable via MCP tooling or the MCP Inspector during debugging. If you intend to publish to PyPI or your environment, follow the publish steps documented in the project (uv publish).

Tips and caveats:

• The MCP Inspector can help debugging since MCP servers run over stdio. You can launch it with the recommended command shown in the repository to attach to a running server instance.
• If you modify configuration or prompts, rebuild or re-sync with uv sync and uv build as appropriate for your workflow.
• Environment variables such as authentication tokens or server endpoints may be required for production deployments; document and export them as needed (see project docs for exact names).
• The server communicates state changes to clients when notes are added; ensure clients subscribe to resource change events to observe updates in real-time.
• When using the published configuration, prefer the uvx command with the server name as an argument to ensure a clean startup path in hosting environments.
