Model Context Protocol

This server implements the Model Context Protocol (MCP), a standard protocol for AI tools that allows AI assistants to:

1. Discover available tools
2. Understand tool capabilities and required parameters
3. Call tools with appropriate parameters
4. Receive structured responses

The MCP implementation uses the @modelcontextprotocol/sdk package to facilitate communication between the AI assistant and the Bitbucket Cloud API.
