## Welcome

Brickken exposes the tokenization platform through five developer and agent surfaces:

* **Dapp API** for API-key authenticated tokenization, STO, security-token, and read workflows.
* **Agentic API** for private-key based ERC-8004 agent and agent-token workflows.
* **MCP** for MCP-compatible AI agents.
* **CLI** for local terminal workflows using the public `brickken-cli` package.
* **Skill** for AI agents that need Brickken-specific API, CLI, and MCP guidance.
