Adds --transport http mode so docker-mcp can run as a long-lived container accessible at http://localhost:<port>/mcp rather than requiring a stdio subprocess on the host. Transport is selected via --transport flag or DOCKER_MCP_TRANSPORT env var (default: stdio, preserving backward compatibility). Host and port are configurable via --host/--port or DOCKER_MCP_HOST/DOCKER_MCP_PORT. Adds: - HTTP transport using mcp.server.streamable_http_manager (stateless mode, no session state between requests) - /health endpoint for container health checks - Dockerfile (Alpine-based, includes docker-cli for socket access) - docker-compose.example.yml showing socket mount pattern Bumps mcp>=1.6.0 (minimum for Streamable HTTP support) and adds explicit starlette and uvicorn dependencies.

What this adds
--transport httpmode so docker-mcp can run as a long-lived container accessible athttp://localhost:<port>/mcprather than requiring a stdio subprocess on every client machine.Changes
server.py— adds_create_starlette_app()usingStreamableHTTPSessionManager(stateless mode) and updatesmain()to accept--transport,--port,--hostargs (also readable fromDOCKER_MCP_TRANSPORT,DOCKER_MCP_PORT,DOCKER_MCP_HOSTenv vars). stdio remains the default — fully backward-compatible.pyproject.toml— bumpsmcp>=1.6.0(minimum for Streamable HTTP support), adds explicitstarletteanduvicorndeps.Dockerfile— Alpine-based image withdocker-cliinstalled sopython-on-whalescan reach the socket. Defaults to HTTP transport on port 8080.docker-compose.example.yml— shows the socket-mount deployment pattern.Usage
Containerised (new):
MCP client config:
{ "mcpServers": { "docker-mcp": { "type": "http", "url": "http://localhost:4001/mcp" } } }stdio (unchanged):
docker-mcp # or: docker-mcp --transport stdioTested
