Can I use mcp-use with Python 3.10?

Question

Does mcp-use support Python 3.10? My team is still on Python 3.10 and the pyproject restricts the supported Python range. Can it be expanded, and what happens if I run mcp-use on Python 3.10 anyway?

AgentArmorHQ team · Accepted Answer

Python 3.10 support is not planned; the request was closed as NOT_PLANNED. A maintainer explained that migrating the code is simple, but running any example on Python 3.10 produces a very ugly error caused by an asyncio change between Python 3.10 and 3.11 that improves how garbage collection interacts with async event loop termination. The tool can run on Python 3.10, but only if client sessions are closed manually; the maintainer worried that documenting this would cause more problems and confusion than benefit. They said that if enough people need 3.10 support they can do it, so comment or react on the issue to show demand. General advice: run mcp-use under Python 3.11+ (for example, in a separate venv or container) while the rest of the team stays on 3.10.

A commenter asked if they could pick up the work. The thread does not state what happened afterward.
