MCP Server

StellarTools exposes a Model Context Protocol (MCP) server so agents in Cursor, Claude Desktop, and other MCP clients can work with your customers, products, checkouts, subscriptions, payments, and refunds. You need an API key from dashboard.stellartools.dev/api-keys.

Endpoint

https://api.stellartools.dev/mcp

Authentication

Send your API key on every connection in the x-api-key header. StellarTools resolves the key to your organization and environment before any tool runs.

x-api-key: sk_test_...

If the key is missing or invalid, tool calls return an error result. Use a testnet key while developing and switch to mainnet when you go live.

Connect in Cursor

Add this to your project or user MCP config (.cursor/mcp.json or Cursor Settings → MCP):

{
  "mcpServers": {
    "stellartools": {
      "url": "https://api.stellartools.dev/mcp",
      "headers": {
        "x-api-key": "sk_test_your_key_here"
      }
    }
  }
}

Replace the key with yours. Restart Cursor or reload MCP servers after saving.

Connect in Claude Desktop

In claude_desktop_config.json:

{
  "mcpServers": {
    "stellartools": {
      "url": "https://api.stellartools.dev/mcp",
      "headers": {
        "x-api-key": "sk_test_your_key_here"
      }
    }
  }
}

Available tools

Tool names and inputs mirror the REST API. Arguments are merged into the shape expected by each route (path params, query, and body fields in one object).

Tool	Description
`create_customers`	Create one or more customers
`create_product`	Create a product
`create_refund`	Create a refund
`delete_checkout`	Delete a checkout (`id`)
`delete_customer`	Delete a customer (`customerId`)
`delete_product`	Delete a product (`id`)
`get_balance`	Stellar account balance for your org wallet
`get_checkout`	Get a checkout (`id`)
`get_customer`	Get one customer by ID (`customerId`)
`get_customers`	List customers for your organization

`get_subscriptions`	List subscriptions
`update_checkout`	Update a checkout (`id` + fields)
`update_customer`	Update a customer (`customerId` + fields)
`update_product`	Update a product (`id` + fields)

Successful tool calls return JSON in the MCP text content. For field-level detail on each resource, see the API Reference.
