Environment

Name	Required	Notes
HCS_API_TOKEN	Yes	API token for the HiddenContent service. Get one at https://hiddencontent.ai/start?ref=mcp-registry — the server refuses to start without it and says so. Secret.
HCS_URL	No	Base URL of the service. Defaults to the hosted API; set it only when pointing at a self-hosted instance.
HCS_CAPABILITIES	No	Comma-separated list of what your agent can actually do. The only accepted values are `tool-use`, `network-egress` and `code-execution`. These turn on the checks for concealed text that instructs a model to call a tool, send data or run code — declaring more can raise severity and never lowers it, and declaring nothing leaves those checks inert. Defaults to `tool-use` in the bundle install.
