Docker MCP alternatives
Docker's MCP Gateway runs, secures, and aggregates other containerized MCP servers behind one endpoint, pulling them on demand from the Docker MCP Catalog with tools like mcp-find, mcp-add, and mcp-exec. It is an aggregator, not a server that does one specific job, so what you want instead depends on whether you need the routing layer at all.
Most teams reach for the Gateway to wrap a handful of underlying servers. If you only run one or two, pointing your client straight at them is simpler. The list below mixes the reference servers Docker would aggregate with a couple of heavier alternatives for when you want a single capability rather than a fleet behind a gateway.
The 8 best alternatives
Fetch is one tool that pulls a URL and returns the page as clean markdown. If the Gateway was mostly fronting a web reader, run this directly and skip the routing layer.
Set up Fetch →The reference Memory server keeps a local knowledge graph of entities, relations, and observations across sessions, which is the kind of single-purpose server you would otherwise register behind the Gateway.
Set up Memory →Reliable current-time lookups and timezone conversion from the IANA database, with just get_current_time and convert_time. There is no reason to gateway something this small.
Set up Time →For local repo work, the Git reference server reads status, diffs, and history and writes commits and branches against a repo path, all over stdio on your machine.
Set up Git →- FilesystemOfficial
Secure local file access, scoped to directories you allow: read, write, edit, search, and explore. It runs locally over stdio, the same model the Gateway uses for the servers it hosts.
Set up Filesystem → - KubernetesCommunity
Where Docker manages containers, the Kubernetes server lists and inspects cluster resources, pods, and Helm releases through the Kubernetes API, the right tool once your agent's job is the cluster rather than single containers.
Set up Kubernetes → GitHub's official server handles repos, issues, pull requests, Actions, and code search, and offers both a local install and a hosted endpoint. It covers source control rather than container plumbing.
Set up GitHub →Sonar's server brings SonarQube code quality, security, and coverage analysis into the agent, an adjacent concern to Docker rather than a replacement: it inspects the code you ship, not the containers.

How to choose
Docker's Gateway earns its place only when you genuinely run several MCP servers and want one endpoint with on-demand discovery. If you run one or two, point your client at them directly: Fetch, Git, Filesystem, and Time each do a single job over stdio with nothing to aggregate. Kubernetes and GitHub fit when the agent's real target is a cluster or a code host rather than containers.
FAQ
- Is the Docker MCP Gateway a replacement for individual MCP servers?
- No. The Gateway aggregates other servers behind one endpoint and adds discovery from the Docker MCP Catalog. If you only run a couple of servers, connecting to each one directly removes a moving part. The reference servers here are the kind it would front.
- Can I run these alternatives locally like the Docker Gateway?
- Yes. Fetch, Memory, Time, Git, Filesystem, Kubernetes, and SonarQube all install and run on your own machine over stdio. GitHub additionally offers a hosted remote endpoint if you would rather not run it yourself.
