Open Parties and Claims

Source-provided project description. FreeMinecraftMods keeps creator credit and adds separate compatibility and decision guidance below.

Project overview

The mod is currently in Beta! This mod adds the ability to claim and to forceload world chunks, as well as create and manage player parties. It also gives server owners powerful controls over their players' usage of the mod's features. By default, claims are owned by individual players who are able to make protection exceptions based on party relations or custom player groups. Server owners can also turn on party-owned claims which is explained in the FAQ below. The mod's API allows other mods or plugins to easily interact with the parties and the chunk claims, both on the server and the client side. The mod already integrates with Xaero's Minimap and World Map mods. Make sure to update them to the latest versions. The API of the mod allows the implementation of player permission systems to be used by the mod for some permission nodes (e.g. for having rank-based claim limits), with Prometheus, FTB Ranks, LuckPerms and the Forge/Fabric permission APIs having built-in support. It also allows the implementation of party systems to be used by claims alongside or instead of the default party system, with Argonauts and FTB Teams having built-in support. The default party system or claims can be disabled completely in the main config file. Commands: /openpac … - player config commands /openpac-claims … - everything claim-related /openpac-parties … - everything party-related /opm - shortcut for the party chat Key Bindings: ' - open the mod UI. Can be changed in the controls menu. Configs: [world directory]/serverconfig/openpartiesandclaims-server.toml - the usual location of the main config file. Make sure to shut down the server before editing it, or the server might overwrite all your changes. [server directory]/config/openpartiesandclaims-server.toml - sometimes the location of the main config file on Fabric/Quilt. [world directory]/serverconfig/openpartiesandclaims-… - some global "player configs", although all of them can be accessed in game through the UI Permission Nodes: The permission nodes that this mod looks up for various reasons are not just static paths. They can be configured in the main config file, e.g. option "maxPlayerClaimsPermission". The used permission system (FTB Ranks, LuckPerms etc) can be configured with the "permissionSystem" option in the main config file. If you or the modpack you are using have not changed the permission nodes, then the permission node paths should be the following: "xaero.pac_max_player_groups" - The meta value permission that should override the default "maxPlayerGroups" option value in the main config. "xaero.pac_player_group_space" - The meta value permission that should override the default "playerGroupSpace" option value in the main config. "xaero.pac_max_claims" - The meta value permission that should override the default "maxPlayerClaims" option value in the main config. "xaero.pac_max_forceloads" - The meta value permission that should override the default "maxPlayerClaimForceloads" option value in the main config. The permission override only takes effect after the player logs in at least once after a server (re)launch, so it is recommended to keep all permission-based forceload limits equal to or greater than "maxPlayerClaimForceloads". "xaero.pac_server_claims" - The permission that gives non-OP players the ability to make server claims and enable server claim mode. "xaero.pac_admin_mode" - The permission that gives non-OP players the ability to enable claim admin mode. FAQ 1) How do I configure the mod on my server? The mod is mainly configured through the main config file at [world directory]/serverconfig/openpartiesandclaims-server.toml , or sometimes [server directory]/config/openpartiesandclaims-server.toml on Fabric/Quilt, while the server isn't running. Server claim, expired claim and wilderness configs, as well as the default player config, can be edited by OPs in-game with the UI (check your key bindings). Normal players can configure their own player config with the same UI. If the mod isn't installed on the client side, then you can use the player config chat commands instead. 2) How do I use this mod as a regular player? Most things related to claims can be accessed with the in-game UI (check your key bindings). If you have the Xaero's World Map mod installed, you can view and edit your claims on the map screen as well, by right-clicking on the map or dragging with the right mouse button to make a selection. You can also use chat commands to make/edit claims. Parties can only be created and managed through chat commands at the moment. 3) Why are some options greyed out in my player config? The server admin/owner can configure with the main config file option playerConfigurablePlayerConfigOptions which specific options players have access to. Everything else uses the value in the default player config. 4) How do I disable all protection on my server? In the server claim, expired claim and wilderness configs, as well as the default player config, disable the main protection option. Next, edit the config file [world directory]/serverconfig/openpartiesandclaims-server.toml (sometimes in [server directory]/config ), while the server isn't runnin

FreeMinecraftMods decision guide

This mod is most relevant to players looking for Server Utility, API and Library on Fabric, Quilt, NeoForge, Forge. Treat those labels as discovery hints, then verify the exact file and dependency list on the official project page.

The source record was updated on Jul 25, 2026, which is a recent freshness signal. A recent date does not guarantee support for every loader or Minecraft version, so still inspect the current file list.

What to verify before choosing a file

• Confirm that the file is published by the credited creator on the linked official source.
• Match the Minecraft version exactly instead of relying only on a broad category label.
• Read dependencies, incompatibilities, and changelog notes before updating an existing instance.
• Match the loader or server platform and its required version. Forge and NeoForge are not interchangeable.
• Back up worlds and configuration files before testing the project in a long-term save or public server.
