What is measured is what a manifest declares, not what a piece of software does. This registry fetches no repository URL, no endpoint and no package index; nothing here is verified. Which value comes from which source, and by which rule it was formed, is set out in the Methodology.

| Environment variable descriptions (raw) | UMBRIEL_ALLOW=Comma-separated tool names or categories to additionally allow on top of the profile. · UMBRIEL_AUDIT=Controls the default-on stderr audit of mutating tool calls. 'off' is the explicit opt-out (reported at startup); 'verbose' also audits reads. · UMBRIEL_CURSOR=Set to 'never' to forbid the real-cursor fallback entirely (strictly cursor-free). By default clicks/drags are cursor-free but fall back to the real hardware cursor when no cursor-free path exists. · UMBRIEL_DENY=Comma-separated tool names or categories to deny, overriding the profile and UMBRIEL_ALLOW. · UMBRIEL_FFI_TRACE=File path to a flush-before-call diagnostic journal of every COM vcall (slot, this-pointer, arg count). Each line is written and flushed to the OS BEFORE the native call, so after an uncatchable crash the last line names the faulting call. Has per-call overhead; unset = off. For debugging native faults only. · UMBRIEL_FS_ROOT=Sandbox root directory that the fs-category file tools (read_file/write_file/list_dir/stat_path/make_dir/copy_file/move_file/delete_file) are confined to when fs tools are enabled; open_path's path argument is honored too. · UMBRIEL_OS=Set to '1' to allow the 'os' tools (launch_app/run_program/open_path, kill_process, manage_process, control_service, set_env, registry_get/registry_list/registry_set) AND the 'fs' tools (read_file/write_file/list_dir/stat_path/make_dir/copy_file/move_file/delete_file) regardless of profile. · UMBRIEL_PROFILE=Capability profile: 'readonly' (inspect/read only), 'safe' (read + input + window — default), or 'full' (also os + fs tools). · UMBRIEL_REDACT=Credential masking (default on). 'off' opts out; a regex value overrides the built-in secret shapes masked in clipboard/env/registry reads and the trace journal. · UMBRIEL_TRACE=File path to journal every mutating tool call as JSON Lines (tool, category, masked args, ok, observation); secret-bearing args and values are redacted.

Embed this badge
Paste this line into a README of your own. The badge states how many values the registry holds for the entry and when it last looked, and it links back to this page.
[](https://tracevero.com/mcp/io-github-obscuritysrl-umbriel)
The image is drawn again on every request, so it always reports the current state while the pasted line stays as it is. It carries no rating and no traffic light – only the two measured figures.
