## SDKs, CLI & MCP

Free

Use the developer tools to integrate and operate Bird. Product subscriptions, API usage and third-party AI services may have their own charges.

- Bird SDKs for your application
- Bird CLI for terminal workflows
- Bird MCP for compatible AI clients
- Published API documentation and guides

## The same product. The same usage rate.

Send an SMS through an SDK, the CLI or MCP and you pay the same SMS rate and carrier fees.

### Keep third-party costs in view

Your AI client or model provider may charge for its service. Those charges are separate from Bird usage and follow that provider’s agreement.

### Is there an extra Bird fee for using MCP?

The Bird MCP tool is included. Billable operations performed through it follow the pricing of the underlying Bird product.

### Are model or AI-client fees included?

A third-party AI client or model provider has its own pricing. Check that service’s terms separately.

### Can I try a product for free through the tools?

Where a Bird product offers a free plan or allowance, its limits apply to usage through the tools too. Review the product’s pricing page before running billable operations.

### Do the tools change a product's billing unit?

No. A request made through an SDK, CLI or MCP follows the underlying product's pricing. The tool does not turn paid API usage into free usage.

### How can I estimate the cost of an automated task?

Identify the products and operations the task will call, then estimate their usage with the applicable rates. Include repeated calls and separate third-party model or client charges.

## Put it into practice.

Choose your tools and connect them to Bird.
