mcp-dockhand CLAUDE.md

mcp-dockhand CLAUDE.md is an instructions file for coding agents from strausmann/mcp-dockhand. It costs 1,009 tokens per session, scanned A, original, MIT.

A repository instruction file documents an MCP server for managing Dockhand, a Docker management system. MCP is a standard way for AI assistants to call tools, and Docker runs applications in isolated containers.

In plain words
What is it for?
For guiding work on the server, including its container, stack, image, network, volume, and Git-stack management tools.
Why use it?
It gives coding assistants a shared description of the project, its technologies, file layout, and development commands.

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.

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

mcp-dockhand CLAUDE.md 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 5d 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.

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.

Konventionen

Code-Stil

  • Alle Tool-Parameter mit Zod validieren
  • encodeURIComponent() auf ALLEN Pfad-Parametern (Container-IDs, Stack-Namen etc.)
  • Environment-ID als environmentId (number) — IMMER als Query-Parameter ?env=
  • Session-basierte Auth — automatisches Re-Login bei 401
  • SSE für Deploy-Operationen (postSSE Methode)

Tool-Definition Pattern

server.tool(
  'tool_name',
  'Beschreibung was das Tool tut',
  {
    environmentId: z.number().describe('Environment ID (required)'),
    name: z.string().describe('Resource name'),
    // Optionale Parameter:
    option: z.string().optional().describe('Optional parameter'),
  },
  async ({ environmentId, name, option }) => {
    const client = await getClient(session);
    const result = await client.get(`/api/endpoint/${encodeURIComponent(name)}`, { env: environmentId });
    return { content: [{ type: 'text', text: JSON.stringify(result, null, 2) }] };
  }
);

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.
