dockhand-mcp

MCP (Model Context Protocol) sidecar server for Dockhand (GitHub). Exposes Dockhand's container, image, volume, network, and stack management as MCP tools over Streamable HTTP, so MCP clients (Claude Desktop, Claude Code, etc.) can manage Docker resources through Dockhand.

This is a standalone service — it does not modify Dockhand itself, and calls Dockhand's existing REST API using a Dockhand API token.

Configuration

Var

Required

Description

DOCKHAND_URL

yes

Base URL of the Dockhand instance, e.g. http://dockhand:3000

DOCKHAND_API_TOKEN

one of these two

Dockhand API token (create one in Dockhand under Profile → API tokens)

DOCKHAND_API_TOKEN_FILE

one of these two

Path to a file/Docker secret containing the token

MCP_AUTH_TOKEN

yes

Shared secret required by MCP clients calling this sidecar

MCP_ALLOWED_HOSTS

no

Comma-separated list of exact hostnames to allow via DNS-rebinding host-header validation. Unset by default — no host filtering is applied, and MCP_AUTH_TOKEN remains the primary access-control gate.

DOCKHAND_MCP_READONLY

no (default false)

Set true to only register read/list/inspect tools

DOCKHAND_MCP_ENABLE_BACKUPS

no (default false)

Set true to register backup config/snapshot tools

DOCKHAND_MCP_ENABLE_USERS

no (default false)

Set true to register user and role tools

DOCKHAND_MCP_ENABLE_REGISTRIES

no (default false)

Set true to register the registry listing tool

DOCKHAND_MCP_ENABLE_VULNERABILITIES

no (default false)

Set true to register vulnerability listing and scan tools

DOCKHAND_MCP_ENABLE_GIT

no (default false)

Set true to register git-backed stack tools

DOCKHAND_MCP_ENABLE_SCHEDULES

no (default false)

Set true to register schedule tools

PORT

no (default 8787)

Port the MCP endpoint listens on

Related MCP server: rancher-mcp

Running

docker build -t dockhand-mcp .
docker run -p 8787:8787 \
  -e DOCKHAND_URL=http://dockhand:3000 \
  -e DOCKHAND_API_TOKEN=dh_... \
  -e MCP_AUTH_TOKEN=... \
  dockhand-mcp

See docker-compose.example.yaml for running alongside Dockhand itself.

On startup, the sidecar checks connectivity to DOCKHAND_URL by calling GET /api/environments and logs the result, along with the minimum supported Dockhand version. A failed check is logged as an error but does not prevent the server from starting — Dockhand may simply not be ready yet — so tool calls will fail individually with clear errors until Dockhand is reachable. Dockhand does not expose its own app version through a REST endpoint, so the minimum-version notice is informational rather than actively enforced.

MCP endpoint

POST /mcp — Streamable HTTP MCP endpoint. Requires Authorization: Bearer <MCP_AUTH_TOKEN>.

GET /health — unauthenticated liveness check.

Client configuration

Example .mcp.json for Claude Code (or ~/.claude.json for a user-scoped config), pointing at a deployed sidecar:

{
  "mcpServers": {
    "dockhand-mcp": {
      "type": "http",
      "url": "https://dockhand-mcp.example.com/mcp",
      "headers": {
        "Authorization": "Bearer ${MCP_AUTH_TOKEN}"
      }
    }
  }
}

Equivalent CLI command:

claude mcp add dockhand-mcp --transport http https://dockhand-mcp.example.com/mcp --header "Authorization: Bearer ${MCP_AUTH_TOKEN}"

${MCP_AUTH_TOKEN} expands from the environment Claude Code runs in — set it to the same value configured on the sidecar, rather than hardcoding the token in the config file.

Tools

Every tool except list_environments, list_users, get_user, list_roles, list_registries, and list_schedules requires an environmentId (or an id scoped to a specific stored resource) — call list_environments first to discover valid environment IDs.

Mutating tools are also disabled whenever DOCKHAND_MCP_READONLY=true, regardless of the domain toggle below.

To enable a domain, set its toggle to true in the sidecar's environment (see Configuration), e.g.:

docker run -p 8787:8787 \
  -e DOCKHAND_URL=http://dockhand:3000 \
  -e DOCKHAND_API_TOKEN=dh_... \
  -e MCP_AUTH_TOKEN=... \
  -e DOCKHAND_MCP_ENABLE_BACKUPS=true \
  -e DOCKHAND_MCP_ENABLE_GIT=true \
  dockhand-mcp

These six domains intentionally wrap only a minimal slice of Dockhand's REST surface for each area (no user/role/registry/git-credential CRUD) — full CRUD for these domains is out of scope, consistent with the project's minimal, LLM-friendly tool surface.
