FastMCP 2.8 is here, and it's all about taking control of your tools.
This release is packed with new features for curating the perfect LLM experience:
🛠️ Tool Transformation
The headline feature lets you wrap any tool—from your own code, a third-party library, or an OpenAPI spec—to create an enhanced, LLM-friendly version. You can rename arguments, rewrite descriptions, and hide parameters without touching the original code.
This feature was developed in close partnership with Bill Easton. As Bill brilliantly [put it](https://www.linkedin.com/posts/williamseaston_huge-thanks-to-william-easton-for-providing-activity-7338011349525983232-Mw6T?utm_source=share&utm_medium=member_desktop&rcm=ACoAAAAd6d0B3uL9zpCsq9eYWKi3HIvb8eN_r_Q), "Tool transformation flips Prompt Engineering on its head: stop writing tool-friendly LLM prompts and start providing LLM-friendly tools."
🏷️ Component Control
Now that you're transforming tools, you need a way to hide the old ones! In FastMCP 2.8 you can programmatically enable/disable any component, and for everyone who's been asking what FastMCP's tags are for—they finally have a purpose! You can now use tags to declaratively filter which components are exposed to your clients.
🚀 Pragmatic by Default
Lastly, to ensure maximum compatibility with the ecosystem, we've made the pragmatic decision to default all OpenAPI routes to Tools, making your entire API immediately accessible to any tool-using agent. When the industry catches up and supports resources, we'll restore the old default -- but no reason you should do extra work before OpenAI, Anthropic, or Google!
