Python DSL for Amazon Connect contact flow generation

CxBlueprint

Programmatic Amazon Connect contact flow generation using Python. Lets AI models and developers build contact flows from plain English instead of hand-writing JSON.

23 of 54 AWS Connect block types supported (43%) — covers all common IVR, routing, A/B testing, and queue transfer patterns. Includes an MCP server for AI-assisted flow generation with Claude Desktop, Cursor, and VS Code.

Simple Example

from cxblueprint import Flow

flow = Flow.build("Burger Order")

welcome = flow.play_prompt("Welcome to Burger Palace!")
menu = flow.get_input("Press 1 for Classic Burger or 2 for Veggie Burger", timeout=10)
welcome.then(menu)

classic = flow.play_prompt("You selected Classic Burger. Your order is confirmed!")
veggie = flow.play_prompt("You selected Veggie Burger. Your order is confirmed!")
error_msg = flow.play_prompt("Invalid selection. Goodbye.")

disconnect = flow.disconnect()

menu.when("1", classic) \
    .when("2", veggie) \
    .otherwise(error_msg) \
    .on_error("InputTimeLimitExceeded", error_msg) \
    .on_error("NoMatchingCondition", error_msg) \
    .on_error("NoMatchingError", error_msg)

classic.then(disconnect)
veggie.then(disconnect)
error_msg.then(disconnect)

flow.compile_to_file("burger_order.json")

Terraform Template Example

Use placeholders for dynamic resource ARNs:

from cxblueprint import Flow

flow = Flow.build("Counter Flow")

welcome = flow.play_prompt("Thank you for calling!")
invoke_counter = flow.invoke_lambda(
    function_arn="${COUNTER_LAMBDA_ARN}",  # Resolved by Terraform
    timeout_seconds="8"
)
welcome.then(invoke_counter)

say_count = flow.play_prompt("You are caller number $.External.count")
invoke_counter.then(say_count)

disconnect = flow.disconnect()
say_count.then(disconnect)
invoke_counter.on_error("NoMatchingError", disconnect)

flow.compile_to_file("counter_flow.json")

Generated Flow Examples

Here's what the generated flows look like in the Amazon Connect console:

Installation

pip install cxblueprint

# With MCP server for AI integration
pip install cxblueprint[mcp]

MCP Server

CxBlueprint includes an MCP server that lets AI tools (Claude Desktop, Cursor, VS Code) build contact flows conversationally.

Configure Claude Desktop (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "cxblueprint": {
      "command": "cxblueprint-mcp"
    }
  }
}

Then ask Claude: "Build me an IVR with a welcome message and 3 menu options for sales, support, and billing"

The AI reads the bundled documentation automatically and uses the compile_flow tool to generate valid Amazon Connect JSON.
