README

Square Model Context Protocol Server (Beta)

This project follows the Model Context Protocol standard, allowing AI assistants to interact with Square's connect API.

Quick Start

Get up and running with the Square MCP server using npx:

# Basic startup
npx square-mcp-server start

# With environment configuration
ACCESS_TOKEN=YOUR_SQUARE_ACCESS_TOKEN SANDBOX=true npx square-mcp-server start

# local runs
npx /path/to/project/square-mcp-server

Replace YOUR_SQUARE_ACCESS_TOKEN with your actual Square access token. You can obtain your access token by following the guide at Square Access Tokens. You can also set environment variables before running the command.

Configuration Options

Environment Variable	Purpose	Example
`ACCESS_TOKEN`	Your Square API access token	`ACCESS_TOKEN=sq0atp-...`
`SANDBOX`	Use Square sandbox environment	`SANDBOX=true`
`PRODUCTION`	Use Square production environment	`PRODUCTION=true`
`DISALLOW_WRITES`	Restrict to read-only operations	`DISALLOW_WRITES=true`
`SQUARE_VERSION`	Specify Square API version	`SQUARE_VERSION=2025-04-16`

Integration with AI Assistants

Goose Integration

To configure the Square MCP Server with Goose:

# Automatic installation
npx square-mcp-server install

# Get URL for manual installation
npx square-mcp-server get-goose-url

The install command automatically updates your Goose configuration.

```
get_service_info(service: "catalog")
```
Understand: Use get_type_info to learn parameter requirements
```
get_type_info(service: "catalog", method: "list")
```

Execute: Use make_api_request to perform the operation

make_api_request(service: "catalog", method: "list", request: {})
