Docker MCP Server Deployment

Running MCP servers in Docker containers gives you consistent environments, easy scaling, and clean isolation between services.

Why Containerize MCP Servers?

• Consistent runtime across machines
• Isolation from host system dependencies
• Easy to version, share, and deploy
• Works with orchestration (Docker Compose, Kubernetes)

Basic Docker Setup

Create a Dockerfile for your MCP server:

FROM node:20-alpine
WORKDIR /app
RUN npm init -y && npm install @modelcontextprotocol/server-github
COPY config.json .
CMD ["npx", "-y", "@modelcontextprotocol/server-github"]

Docker Compose for Multiple Servers

Run multiple MCP servers together with Docker Compose:

version: "3.8"
services:
  github-mcp:
    build: ./github-mcp
    environment:
      - GITHUB_TOKEN=${GITHUB_TOKEN}
    ports:
      - "3100:3100"
  stripe-mcp:
    build: ./stripe-mcp
    environment:
      - STRIPE_API_KEY=${STRIPE_API_KEY}
    ports:
      - "3101:3101"

Connecting Claude Desktop to Docker MCP Servers

Configure Claude Desktop to connect to your Docker-hosted MCP servers using the host's network:

{"mcpServers":{"github-mcp":{"command":"docker","args":["run","-i","--rm","-e","GITHUB_TOKEN","github-mcp"],"env":{"GITHUB_TOKEN":"your_token"}}}}

Production Considerations

• Use Docker secrets or a secrets manager instead of env vars
• Set resource limits on containers
• Use health checks to monitor uptime
• Log to stdout/stderr for centralized logging
