docker-mcp-implementation

An implementation plan for running a Python MCP server in Docker, a system that packages an application with its dependencies. It specifies container files, client configuration, and changes needed to remove host-machine dependencies.

In plain words
What is it for?
Use it to build and run the MCP server with Docker, manage it with Compose and scripts, configure a client to launch it, and remove external filesystem requirements.
Why use it?
It makes the server less dependent on one computer’s file paths and environment. It also defines a container setup with a non-root user, minimal image, and no network ports.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 1,274 The whole file, excluding the scripts and references it only reads on demand.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

docker-mcp-implementation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Docker MCP Server Implementation Plan

Overview

This document outlines the implementation plan for converting the Python MCP server to use Docker, following the pattern established by the GitHub MCP Server.

Implementation Checklist

✅ Core Docker Files

  • Dockerfile: Multi-stage build with Python 3.11 slim base
  • .dockerignore: Exclude unnecessary files from build context
  • docker-compose.yml: Container orchestration for development
  • build.sh: Comprehensive build and management script

✅ Security Improvements

  • Non-root user: Container runs as mcp user for security
  • Minimal base image: Using Python 3.11 slim to reduce attack surface
  • No exposed ports: Uses stdio transport, no network exposure
  • Clean dependencies: Only essential packages installed

✅ Code Modifications

  • Removed hardcoded paths: Eliminated /Users/sven.scheffel/recipe.txt dependency
  • Simplified add_numbers: Now returns just the calculation result
  • Container-friendly: No file system dependencies outside container

✅ Configuration Files

  • cursor-mcp-config-docker.json: Docker-based MCP client configuration
  • Updated requirements.txt: Maintained existing FastMCP dependency

✅ Documentation

  • README-Docker.md: Comprehensive Docker setup and usage guide
  • Comparison table: Shows differences with GitHub MCP Server
  • Troubleshooting guide: Common issues and solutions
  • Multiple deployment options: Build script, Docker commands, Docker Compose

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

docker-mcp-implementation is a cursor rule published in the GitHub repository SwonVIP/mcp-server-talk (0 stars, last pushed 1y ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,274 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
