mcp/filesystem terminates unexpectedly

[chrissound]

The process terminates unexpectedly? I'm trying to run this standalone, I'll use the API directly.

root@mcp-test:~/servers# docker run --rm -v $PWD:/projects mcp/filesystem /projects
Secure MCP Filesystem Server running on stdio
root@mcp-test:~/servers# echo $?
0

To Reproduce

git clone git@github.com:modelcontextprotocol/servers.git
cd servers
docker build -t mcp/filesystem -f src/filesystem/Dockerfile .
root@mcp-test:~/servers# docker run --rm -v $PWD:/projects mcp/filesystem /projects
Secure MCP Filesystem Server running on stdio

I expect it to instead be continually running.

I had to run docker run -i (interactively), and then paste {"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}} and press enter (push it to stdin of the process)... After which it sends the response to stdout:

root@mcp-test:~/servers# docker run -i --rm -v $PWD:/projects mcp/filesystem /projects
Secure MCP Filesystem Server running on stdio
{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}
{"result":{"tools":[{"name":"read_file","description":"Read t
...

The next mission (not that anyone cares...) is to figure out how to run this remotely as a proper MCP server.
