Overview

What is Square MCP Server by CData?

Square MCP Server by CData is a read-only Model Context Protocol (MCP) server that lets large language models (LLMs) like Claude Desktop query live Square data using natural language. It wraps the CData JDBC Driver for Square, which exposes Square data as relational SQL models, so no SQL knowledge is required.

How to use Square MCP Server by CData?

Clone the repository, build the JAR with Maven (mvn clean install), install and license the CData JDBC Driver for Square, create a .prp file with your JDBC connection string, and add the server entry to your Claude Desktop config (claude_desktop_config.json). Restart Claude and then ask natural-language questions about your Square data — the server handles the querying automatically.

Key features of Square MCP Server by CData

  • Read-only access to live Square data via MCP
  • Exposes Square tables, columns, and SQL query execution as tools
  • Uses stdio transport (client and server must run on the same machine)
  • Built on the CData JDBC Driver for Square (requires separate installation and license)
  • Supports natural language queries through an LLM client
  • Requires Java and Maven for building and running

Use cases of Square MCP Server by CData

  • Query Square sales, customers, or inventory from an AI assistant
  • Analyze transaction trends without writing SQL
  • Integrate Square data into a conversational business intelligence workflow
  • Automate data retrieval for reporting or audit checks

Frequently asked questions

1

Is Square MCP Server by CData read-only?

Yes. This server provides read-only access. For full create, update, delete, and action capabilities with simplified setup, CData offers a paid MCP Server for Square (beta).

2

What are the dependencies to run this server?

You need Java, Maven (for building), the CData JDBC Driver for Square installed and licensed (trial or full key), and a configuration file (`.prp`) with the JDBC URL.

3

Where does my Square data reside?

Data remains in Square. The server fetches live data on each query through the JDBC driver; no data is stored locally by the MCP server.

4

What transport does the server use?

The server uses stdio transport, so it must be started by a client running on the same machine (e.g., Claude Desktop).

5

How do I connect Square to this server?

After installing and licensing the JDBC driver, use its connection string builder to generate a JDBC URL. Store that URL, along with the driver path and class, in a `.prp` file. Then point the MCP client (e.g., Claude Desktop) to the JAR and that `.prp` file.
