What is mcp-dockhand copilot-instructions.md?

Instructions for an MCP server that connects AI tools to Dockhand, a Docker management service. The server wraps Dockhand’s REST API, which is a web interface for sending requests and receiving data.

Reviewing or implementing MCP tools for Docker management, verifying HTTP methods and data formats, and checking Hawser-related integrations.

They require checking Dockhand’s source code so tool methods, request fields, responses, and agent protocols match the real service.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00777	$0.00777
Opus 5.5	$0.00311	$0.00311
Sonnet 5.5	$0.00155	$0.00155
Haiku 4.5	$0.00078	$0.00078

Security

Grade A, and why

mcp-dockhand copilot-instructions.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 1mo 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.

Copilot Instructions — MCP-Dockhand

Project Context

This is a Model Context Protocol (MCP) server for Dockhand Docker Management. It wraps the Dockhand REST API into 130+ MCP tools using Streamable HTTP transport.

Upstream repositories (source of truth for API behavior):

Dockhand Server: https://github.com/finsys/dockhand (SvelteKit, Bun)
Hawser Agent: https://github.com/finsys/hawser (Go)

Critical: Verify Against Upstream

When reviewing MCP tool implementations, always cross-reference with the upstream Dockhand source code:

HTTP Methods: Check src/routes/api/**/+server.ts in finsys/dockhand for the correct HTTP method (GET/POST/PUT/DELETE/PATCH). Our MCP tools MUST match.
Request Body Fields: Check the actual request parsing in the Dockhand route handlers to verify parameter names and types match what our tools send.
Response Format: Verify our tools correctly handle the response structure (JSON object vs array, pagination, error format).
Hawser Protocol: For environment/hawser-related tools, check internal/protocol/messages.go and internal/docker/compose.go in finsys/hawser.
API Schema: Compare against docs/dockhand-openapi.json (pinned upstream OpenAPI spec, single source since #222; refreshed nightly by .github/workflows/api-schema-sync.yml).

If a tool's implementation differs from upstream, flag it as HIGH priority.

Code Review Guidelines

Security

All path parameters MUST use encodePath() from src/utils/encode-path.ts
No hardcoded credentials or tokens
Session cookies must not be logged
Environment filter must be applied on all environment-scoped endpoints
additionalConfig/additionalSettings must be merged BEFORE explicit fields (not after)

MCP Tool Quality

All parameters must have Zod validation with .describe() annotations
Tool descriptions must be clear and actionable for LLMs
Prefer explicit typed parameters over generic Record<string, unknown>
Required vs optional parameters must match the Dockhand API
connectionType gating: host/port only for hawser-standard, not hawser-edge

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.
