<Update label="v2.8.0" description="2024-06-10">
## [v2.8.0: Transform and Roll Out](https://github.com/jlowin/fastmcp/releases/tag/v2.8.0)
FastMCP 2.8.0 introduces powerful new ways to customize and control your MCP servers!
### Tool Transformation
The highlight of this release is first-class [**Tool Transformation**](/patterns/tool-transformation), a new feature that lets you create enhanced variations of existing tools. You can now easily rename arguments, hide parameters, modify descriptions, and even wrap tools with custom validation or post-processing logic—all without rewriting the original code. This makes it easier than ever to adapt generic tools for specific LLM use cases or to simplify complex APIs. Huge thanks to [@strawgate](https://github.com/strawgate) for partnering on this, starting with [#591](https://github.com/jlowin/fastmcp/discussions/591) and [#599](https://github.com/jlowin/fastmcp/pull/599) and continuing offline.
### Component Control
This release also gives you more granular control over which components are exposed to clients. With new [**tag-based filtering**](/servers/fastmcp#tag-based-filtering), you can selectively enable or disable tools, resources, and prompts based on tags, perfect for managing different environments or user permissions. Complementing this, every component now supports being [programmatically enabled or disabled](/servers/tools#disabling-tools), offering dynamic control over your server's capabilities.
### Tools-by-Default
Finally, to improve compatibility with a wider range of LLM clients, this release changes the default behavior for OpenAPI integration: all API endpoints are now converted to `Tools` by default. This is a **breaking change** but pragmatically necessitated by the fact that the majority of MCP clients available today are, sadly, only compatible with MCP tools. Therefore, this change significantly simplifies the out-of-the-box experience and ensures your entire API is immediately accessible to any tool-using agent.
