## Please know that THIS plugin page is only the paper STANDALONE anticheat, not the velocity proxy plugin, not the paper companion. I am writing this as of the 28th of Mars 2026, and the modrinth team is sitll reviewing both plugins, be patient with them as they have a huge workload of mods, plugins, packs and etc… to verify.<\/p>\n
# Grace Anticheat<\/p>\n
> Advanced, free anticheat for Java Minecraft servers (1.19+). Built to catch what others miss.<\/p>\n
Grace targets **closet cheating** and **ghost cheating** these are the subtle, hard-to-detect cheats that plague competitive servers. Blatant hacking is handled too, but it isn’t the focus. <\/p>\n
Unlike Watchdog, Sentinel, and Grim, Grace is free. Unlike NCP and other aging open-source anticheats, Grace is built for modern Minecraft with a rules-based detection pipeline and a statistical behavioral analysis layer.<\/p>\n
The website is live at https:\/\/grace-ac-site.vercel.app\/.<\/p>\n
—<\/p>\n
## Architecture<\/p>\n
Grace runs as a **Velocity proxy plugin** with a **Paper companion plugin** on the backend server.
\n“`
\n[Client] \u2192 [Grace \/ Velocity Proxy] \u2192 [Paper Server + GraceCompanion]
\n“`<\/p>\n
However, this paper plugin standalone runs as follows :
\n“`
\n[Client] \u2192 [Paper Server \/ Grace Paper (Standalone)]
\n“`
\nThis does not mean this variant of the anticheat is less powerful than the velocity based one, it just acts on another layer with some minimal loss in precision.<\/p>\n
—<\/p>\n
The proxy intercepts raw packets. The companion feeds server-confirmed truth : hit registration, movement validation, TPS. Together they give Grace a complete picture of player behavior that neither layer could achieve alone.<\/p>\n
—<\/p>\n
## Requirements (for the standalone)<\/p>\n
– **Paper** 1.19+
\n– **Java** 21+<\/p>\n
—<\/p>\n
## Installation<\/p>\n
**1 \u2014 Backend server**<\/p>\n
This is the standalone paper plugin installation, <\/p>\n
Simply drop the downloaded .jar in \/plugins, and you’re set!<\/p>\n
this plugin downloads like any other, you’ll have to launch the server once after download to get the configuration file and graceAC folder.<\/p>\n
—<\/p>\n
## Configuration
\n“`yaml
\ngrace:
\n bridge:
\n port: 27016 # make sure this port is open \/ not blocked by firewall<\/p>\n
alerts:
\n ingame-enabled: true # alert staff in-game
\n discord-enabled: false # send alerts to Discord
\n webhook-url: “” # paste your Discord webhook URL here
\n min-level: “HARD_ALERT” # SOFT_ALERT \/ HARD_ALERT \/ ACTION<\/p>\n
punishment:
\n enabled: true
\n rubber-band-on-hard-alert: true # teleport player back on HARD_ALERT
\n kick-on-action: true # kick on ACTION tier
\n ban-on-action: false # auto-ban (disabled by default)
\n ban-threshold: 3 # ACTION flags before ban
\n kick-message: “Kicked by Grace Anticheat.”
\n ban-message: “Banned by Grace Anticheat.”<\/p>\n
spoof:
\n brand: “vanilla” # spoof server brand to hide Grace from cheat clients
\n enabled: true

## Commands<\/p>\n
| Command | Permission | Description | —<\/p>\n ## Discord Alerts<\/p>\n Grace can send formatted embeds to a Discord channel when a player is flagged.<\/p>\n 1. Go to your staff channel \u2192 **Edit Channel** \u2192 **Integrations** \u2192 **Webhooks** \u2192 **New Webhook** \u2192 **Copy Webhook URL** —<\/p>\n ## Open Source<\/p>\n Grace’s **framework** – the API, event pipeline, data model, and companion plugin is open source.<\/p>\n Grace’s **detection logic** – check implementations, model weights, and threshold tuning is closed source. This is intentional. Open detection logic is a bypass roadmap for cheat developers.<\/p>\n —<\/p>\n ## Status<\/p>\n **Beta 0.1.0** – active development. Expect bugs. Thresholds are conservative by default to minimize false positives on first deployment. If Grace is missing cheaters on your server, thresholds can be tuned in config.<\/p>\n Bug reports and feedback welcome via GitHub Issues.<\/p>\n —<\/p>\n ## Roadmap<\/p>\n – **0.1.0** \u2014 ML sidecar (grace-ml) first iteration, behavioral analysis layer, complete checks and advaned setup help for early servers. This is a new, top of the line, rules-based with a ML pipeline, modern anticheat.<\/p>\n","protected":false},"featured_media":77452,"template":"","meta":{"_minecraft_slug":"graceac","_minecraft_project_id":"8ob1cAY1","_minecraft_author":"itss.me1","_minecraft_license":"LicenseRef-GraceAC-API-and-Companion-License","_minecraft_downloads":58,"_minecraft_follows":0,"_minecraft_client_side":"unsupported","_minecraft_server_side":"required","_minecraft_storage_type":"zip","_minecraft_archive_name":"graceac.zip","_minecraft_size_bytes":4675522,"_minecraft_version_count":3,"_minecraft_updated_at":"2026-05-15T20:50:37.356955Z","_minecraft_date_created":"2026-03-24T23:28:01.797925Z","_minecraft_date_modified":"2026-03-29T14:46:51.940555Z","_minecraft_project_url":"https:\/\/modrinth.com\/mod\/graceac","_minecraft_icon_attachment_id":77452,"_minecraft_imported_at":"2026-06-04T11:21:22+00:00","_minecraft_import_hash":"1d95c5aa6a9108a5a020bd4a59743e95","_minecraft_versions":"","_minecraft_links":"","_minecraft_gallery":"","_minecraft_api_metadata":""},"mod_category":[89,126,127,92],"mod_loader":[132],"minecraft_version":[54,55,56,57,58,59,36,60,93,94,101,102,62,37,40,41,73,74,38,78,79,80,81,82],"class_list":["post-77451","mod","type-mod","status-publish","has-post-thumbnail","hentry","mod_category-game-mechanics","mod_category-management","mod_category-paper","mod_category-utility","mod_loader-paper","minecraft_version-1-19","minecraft_version-1-19-1","minecraft_version-1-19-2","minecraft_version-1-19-3","minecraft_version-1-19-4","minecraft_version-1-20","minecraft_version-1-20-1","minecraft_version-1-20-2","minecraft_version-1-20-3","minecraft_version-1-20-4","minecraft_version-1-20-5","minecraft_version-1-20-6","minecraft_version-1-21","minecraft_version-1-21-1","minecraft_version-1-21-10","minecraft_version-1-21-11","minecraft_version-1-21-2","minecraft_version-1-21-3","minecraft_version-1-21-4","minecraft_version-1-21-5","minecraft_version-1-21-6","minecraft_version-1-21-7","minecraft_version-1-21-8","minecraft_version-1-21-9"],"yoast_head":"\n
