Is there a free trial?

Yes. Start a free 3-day trial from your account at codefizz.dev/account, no credit card required. The trial unlocks the full Pro plugin for UE 5.6, 5.7 and 5.8 on one machine. When it ends, upgrade to a paid plan and the same key keeps working with five machine seats. There is also a separate free, open-source community edition (Unreal MCP).

Which Unreal Engine versions are supported?

UE 5.6, 5.7 and 5.8 on Win64. Each release ships as a separate binary plugin matched to the engine ABI, and the cfa CLI downloads the build that matches the engine you point it at. Future engine versions are added as they release.

Which platforms are supported?

Right now, Windows 64-bit only. The plugin is built and tested on Windows for this first release. Linux and Mac support are on the roadmap and will be added when there is clear demand from paying customers. I would rather wait until I can properly test those builds end to end than ship binaries I have not run myself. If you are on Mac or Linux and would buy the plugin today, drop a note in Discord or send me an email. That is how the priority for adding those platforms gets set.

Do I need a license key, and how do I enter it?

Activate from the CLI with your CodeFizz website account. Install or update the free cfa CLI, run cfa login, and sign in in the browser. That machine is activated and the editor plugin reads the same sign in, with nothing to paste inside Unreal. Offline grace still applies. A license key remains under License and billing for recovery and older cfa builds (cfa login --key), but new setups should use browser login only.

What MCP clients work with the plugin?

Any MCP-compatible client. The plugin exposes a TCP bridge and the Go CLI ships separately, so Claude Code, Cursor, VS Code, Gemini, and other MCP hosts all work out of the box.

Can I cancel anytime?

Yes. Open your account at codefizz.dev/account and click Manage billing to open the Polar billing portal, then cancel in one click. You keep access through the end of your billing period and stop being charged afterward.

What happens to my installed plugin if I cancel?

You keep the version you installed and it keeps working. Your license stays valid after you cancel, so the plugin does not switch off. You stop receiving new releases and you lose access to the private Discord and roadmap. The plugin you paid for is yours to keep.

Do you offer refunds?

No refunds on subscriptions, since the plugin is downloadable software you get immediately. You can cancel any time and keep access through the end of the period you have already paid for. If you ran into a real bug or a feature you reasonably expected to be there, email me and we will figure it out. Full policy on the Refund Policy page in the footer.

Why is Patron more expensive when I get the same plugin?

Patron is for people who want to influence the direction of CodeFizz Editor Agent, with voting, a private roadmap, priority answers, and direct input on new APIs. If you just need the plugin and updates, stay on Pro.

Is there a free version?

Yes. There is a free, open-source community edition (Unreal MCP) that gives you the core bridge and a basic command set, which is great for trying the workflow. The paid Pro edition is the fully maintained build with the complete toolset (Niagara, PCG, StateTree, Insights, and more), regular updates, and support. The open-source edition is linked in the footer.

Studio / team licensing?

For studios needing multiple seats, an enterprise tier is available off-platform. Contact directly for pricing.

Project Settings

Every Project Settings command in CodeFizz Editor Agent, with parameters and examples.

3 commands. Each shows its parameters and an example, and has a copyable deep link, so you (or an AI agent) can jump straight to one.

search_project_settings

Search Project/Editor Settings sections by name

Fuzzy-searches every registered settings section (the same tree the Project Settings window shows) across all containers. Returns the exact container/category/section/class names and which Default*.ini each writes to. Use this first to discover the exact name, then get_project_settings / set_project_settings. Filter matches container, category, section, display name, and backing class.

Parameter	Type	Required	Description
filter	string	No	Substring matched against category/section/display/class (empty = list all)
container	string	No	Restrict to one container (e.g. Project, Editor)
max_results	int	No	Maximum sections to return

example

cfa search_project_settings --filter "map" --max-results 5

get_project_settings

Read all properties of a settings section

Returns every property of one settings section with type, current value, and metadata (for enums the valid_values, for class/object refs the required base class, plus editable/readonly flags). Identify the section by class_name (e.g. GameMapsSettings) OR section (+ optional category/container). Use filter to narrow to matching property names.

Parameter	Type	Required	Description
class_name	string	No	Backing settings class (e.g. GameMapsSettings). One of class_name/section required.
container	string	No	Container name (e.g. Project) to disambiguate
category	string	No	Category name or display name to disambiguate
section	string	No	Section name or display name (e.g. "Maps & Modes")
filter	string	No	Only properties whose path contains this substring
max_results	int	No	Maximum properties to return
include_metadata	bool	No	Include per-property metadata (enum options, class base, flags)

example

cfa get_project_settings --class-name "GameMapsSettings" --filter "Default"

set_project_settings

Set one or more properties on a settings section and persist to Default*.ini

Writes settings via reflection exactly like the Project Settings window: sets the value, fires PostEditChangeProperty, then persists the change to the correct Default*.ini (DefaultEngine.ini, DefaultGame.ini, etc.). Identify the section by class_name OR section (+ optional category/container). Provide property_name + property_value for one write, or a properties map for a batch. Every type works, enums, soft class refs (GameInstance/GameMode/map assets), structs, and arrays (e.g. append a collision profile to Profiles). On a bad value the response tells you what the property actually accepts: valid enum options, the required base class, or did_you_mean for a mistyped name.

Parameter	Type	Required	Description
class_name	string	No	Backing settings class (e.g. GameMapsSettings). One of class_name/section required.
container	string	No	Container name (e.g. Project) to disambiguate
category	string	No	Category name or display name to disambiguate
section	string	No	Section name or display name (e.g. "Maps & Modes")
property_name	string	No	Single property/dotted path to set (with property_value)
property_value	json	No	Value for property_name (any JSON type; asset/class path string for refs)
properties	json	No	Object map of property -> value for batch writes

example

  cfa set_project_settings --class-name "GameMapsSettings" --property-name "ServerDefaultMap" --property-value "/Game/Maps/Lobby.Lobby"
  cfa set_project_settings --class-name "GameMapsSettings" --property-name "GameInstanceClass" --property-value "/Script/MyGame.MyGameInstance"
  cfa set_project_settings --class-name "GameMapsSettings" --properties '{"GameDefaultMap":"/Game/Maps/Main.Main","GlobalDefaultGameMode":"/Script/MyGame.MyGameMode"}'
