 - **OpenCode** built from source from the [`BYK/opencode`](https://github.com/BYK/opencode/tree/byk/cumulative) fork (`byk/cumulative` branch) — carries question-dock UX, plan-mode, and db perf fixes that aren't yet in upstream. Built fresh into the image; auto-update is effectively disabled because the fork has no release feed.
 - [Sentry CLI](https://cli.sentry.dev), GitHub CLI, **nvm + Node 22 LTS** (`pnpm` / `yarn` via corepack), **Bun**, plus `git`, `ripgrep`, `fd`, `fzf`, `jq`, `yq`, and `build-essential`.
-- **Three remote MCP servers** preconfigured; credentials are pulled from env vars via `{env:VAR}` substitution, so nothing sensitive is baked into the image:
-  - [Context7](https://context7.com) → `CONTEXT7_API_KEY`
-  - [GitHub MCP](https://github.com/github/github-mcp-server) → `GITHUB_MCP_TOKEN`
-  - [Sentry MCP](https://mcp.sentry.dev) → no env var
+- No MCP servers preconfigured — add your own via a project-local `opencode.json` or by editing [`opencode-user-config.json`](./opencode-user-config.json) before building.
 - Non-root `developer` user. OpenCode starts in `~/dev`. Mount a single persistent volume at `~/dev` (= `/home/developer/dev`) to keep your projects **and** OpenCode session/auth data across redeploys — `~/.local/share/opencode` is symlinked into `~/dev/.opencode`.
