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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.03167 | $0.03167 |
| Opus 5 | $0.01584 | $0.01584 |
| Sonnet 5 | $0.00633 | $0.00633 |
| Haiku 4.5 | $0.00317 | $0.00317 |
Grade A, and why
docker-mcp-server CLAUDE.md scanned grade A with 1 finding 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 6d ago.
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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Development Commands
Docker Operations
npm run docker:build- Build the Docker image with server codenpm run docker:up- Start the containerized MCP servernpm run docker:down- Stop and remove the containernpm run docker:logs- View server logs (follow mode)npm run docker:restart- Rebuild and restart the containernpm run docker:shell- Open bash shell in running container./reset-docker.sh- Complete reset (stop, clean workspace, rebuild, start)
Local Development
npm run build- Compile TypeScript to JavaScript in/distnpm install- Install dependencies
High-Level Architecture
This is an MCP (Model Context Protocol) Server that runs entirely inside a Docker container and provides command execution capabilities. The server is exposed via HTTP with bearer token authentication.
Core Components
- MCP Server (
src/index.ts) - TypeScript server using@modelcontextprotocol/sdkwithStreamableHTTPServerTransport - HTTP Transport - Network-based communication on port 30000
- Bearer Token Auth - Secure authentication for all requests
- Docker Container - Debian-based container with Node.js, Playwright, and the MCP server
- Workspace Mount - Host
./tmpdirectory mounted to container/app/workspacefor persistent file storage - Process Management - Tracks background processes with unique IDs and timeouts
Container Environment
- Base Image:
node:current-trixie(Debian with current Node.js) - Additional Tools: git, xdg-utils, jq, python3, Playwright with dependencies
- Server Location:
/app(contains built MCP server code) - Working Directory:
/app/workspace(mounted from host./tmp) - Exposed Port: 30000 (mapped to host port 30000)
- Container Name:
mcp-container
Architecture Changes from Previous Version
OLD (Host-Based):
- MCP server ran on host machine
- Used stdio transport (stdin/stdout)
- Commands executed via
docker execinto separate container - Container only provided execution environment
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-server CLAUDE.md is an instructions file published in the GitHub repository kenforthewin/docker-mcp-server (6 stars, last pushed 8mo ago), licensed MIT. It adds 3,167 tokens to every session, about $0.0158 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
