Neon PostgreSQL MCP server

insight is an open-source auroracoin blockchain explorer with complete REST and websocket APIs. It runs in NodeJS, uses AngularJS for the front-end and LevelDB for storage, providing a comprehensive interface for exploring the auroracoin blockchain.

Prerequisites

• Node.js v0.10.x - Download and Install Node.js
• Create a node symlink with this command: ln -s /usr/bin/nodejs /usr/bin/node
• NPM - Node.js package manager (automatically installed with Node.js)

Installation

To install Insight, follow these steps:

1. Clone the repository:

git clone https://github.com/greatwitenorth/insight.git && cd insight

2. Install dependencies:

npm install

3. Run the application:

npm start

4. Access the application by opening your browser and navigating to:

http://localhost:3001

Configuration

If you encounter connection problems with the auroracoind service, you can configure environment variables for proper connection:

INSIGHT_NETWORK=livenet BITCOIND_USER=user BITCOIND_PASS=pass INSIGHT_PUBLIC_PATH=public npm start

Note that the application needs to sync its internal database with the blockchain state, which may take some time. You can monitor the sync progress through the web interface.

Setting Up Nginx as a Reverse Proxy

To use Nginx as a reverse proxy for Insight, you can use the base configuration available here.

Multilanguage Support

Insight supports multiple languages using angular-gettext. The default language can be changed in the configuration file at public/src/js/config:

gettextCatalog.currentLanguage = 'es';

This setting will use the corresponding language file from the po/ folder (like es.po for Spanish).

API Reference

For more details about the Insight API configuration and endpoints, refer to the Insight API GitHub repository.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "neon-mcp" '{"command":"npx","args":["-y","neon-mcp"]}'

See the official Claude Code MCP documentation for more details.

For 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 > Tools & Integrations and click "New MCP Server".

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

{
    "mcpServers": {
        "neon-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "neon-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 explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

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

3. Restart Claude Desktop for the changes to take effect
