mixing options.* with bare config-level attributes (boot.*, environment.*, etc.) at the same level isn't supported once the module declares any options — nix needs them under an explicit 'config = { ... }' block. error from the host: 'unsupported attribute boot. caused by introducing top-level options'. wrap accordingly.

Extra MCP servers claude sees alongside the hyperhive tool surface.

Keys are the server names (claude addresses tools as

`mcp__<key>__<tool>`). Rendered to `/etc/hyperhive/extra-mcp.json`
|

at activation time; the harness reads that file at boot and merges

it into `--mcp-config` + `--allowedTools`. Take effect on the
