LibSQL MCP server

The LibSQL Model Context Protocol Server interfaces with LibSQL databases, providing schema information and enabling table queries. Built using Deno 2.1, this server leverages the Model Context Protocol (MCP) to handle various requests including listing resources, reading schemas, completing prompts, and executing SQL queries.

Requirements

• Deno 2.1+
• A LibSQL database URL

Installation

First, install Deno by running the following command (for macOS/Linux):

curl -fsSL https://deno.land/install.sh | sh

After installing Deno, build the MCP server binary:

deno run build

Running the Server

Basic Usage

To run the server with a local LibSQL database that doesn't require authentication:

./mcp-server-libsql <database-url>

With Authentication

If your LibSQL database requires authentication, use the --auth-token flag:

./mcp-server-libsql --auth-token <token> <database-url>

Examples

Connect to a local SQLite database:

./mcp-server-libsql file:mydb.sqlite

Connect to a remote LibSQL database with authentication:

./mcp-server-libsql --auth-token abc123xyz456 libsql://my-database.turso.io

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
