In Smolagents the docker MCP server does not get stopped

[simoncalabrese]

Hi!
As indicated, I have a Stdio server that is spinned up using docker run.
After I perform the tasks with Smolagents although, the code stays pending and the container is not getting stopped.
Is there a way to fix it?

Hi thanks for reporting an issue with mcpadapt!

Could you please elaborate ? "As indicated" where? what is the code you are trying to run? what mcp server? What are the logs or error message you did receive?

I apologize for the confusion. Sure!
I forked this repo https://github.com/scalabreseGD/mcp-snowflake-server and I run it as follow:

snowflake_server_mcp = StdioServerParameters(
    command='docker',
    args=[
        "run", "-i", "--rm",
        "--name", container_name,
        "mcp-snowflake-server:0.0.3",
        "--account", os.environ.get('SNOWFLAKE_ACCOUNT'),
        "--warehouse", os.environ.get('SNOWFLAKE_WAREHOUSE'),
        "--user", os.environ.get('SNOWFLAKE_USER'),
        "--password", os.environ.get('SNOWFLAKE_PASSWORD'),
        "--role", os.environ.get('SNOWFLAKE_ROLE'),
        "--database", os.environ.get('SNOWFLAKE_DB'),
        "--schema", os.environ.get('SNOWFLAKE_SCHEMA'),
        "--exclude_tools", "append_insight", "list_databases", "list_schemas"
    ]
)

with ToolCollection.from_mcp(snowflake_server_mcp, trust_remote_code=True) as tool_collection:
# rest of the code

Then when I run it in a simple python script, it stays pending after the execution because it can stop the container during the exit mechanism
