[Enhancement]: Replace python 3.12 for 3.13 in image

[lesandie]

What features would you like to see added?

In my case clickhouse-mcp server uses python 3.13 and I wanted to add it to the mcp server list, but I get the error by uv that python 3.13 is a req.

More details

It is nice that uv is included in the image already, and including python 3.13 would be awesome.

Which components are impacted by your request?

I'm able to specify python 3.13 like this (using docker):

mcpServers:
  fetch:
      command: uvx
      args:
        - "--python"
        - "3.13"
        - "mcp-server-fetch"

seems to work!

I'm trying to install the Klaviyo MCP with no luck. I don't see 3.13 being installed in the logging.

  klaviyo:
    type: stdio
    command: uvx
    args:
      - "--python"
      - "3.13"
      - klaviyo-mcp-server@latest
    env:
      PRIVATE_API_KEY: "${KLAVIYO_TOKEN}"
      READ_ONLY: "true"
      ALLOW_USER_GENERATED_CONTENT: "false"
    serverInstructions: true
    chatMenu: true

When I docker exc:

/app # echo '{ "jsonrpc": "2.0", "id": "1", "method": "initialize", "params": {} }' | uvx klaviyo-mcp-server@latest
  x No solution found when resolving tool dependencies:
  `-> Because the current Python version (3.12.11) does not satisfy Python>=3.13 and all versions of klaviyo-mcp-server depend on Python>=3.13, we can conclude that all versions of klaviyo-mcp-server cannot be used.
      And because you require klaviyo-mcp-server, we can conclude that your requirements are unsatisfiable.
/app # echo '{ "jsonrpc": "2.0", "id": "1", "method": "initialize", "params": {} }' | uvx --python 3.13 klaviyo-mcp-server@latest
error: No interpreter found for Python 3.13 in managed installations or search path
/app #

Is there something i'm doing wrong?
