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.

Debug

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

2 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.

set_mcp_debug

Enable or disable MCP debug mode (token tracking)

Toggles MCP debug mode which enables token usage tracking on every MCP command. When enabled, the bridge measures the approximate token size of each request and response, accumulates totals per command, and tracks call counts. Use get_mcp_token_stats to read the accumulated statistics. Useful for identifying which commands produce oversized responses that waste LLM context budget.

Parameter	Type	Required	Description
enabled	bool	No	Enable debug mode

example

cfa set_mcp_debug --enabled
cfa set_mcp_debug --enabled=false

get_mcp_token_stats

Get MCP token usage statistics

Returns accumulated token usage statistics from the MCP bridge. Shows per-command call counts, total input/output tokens, and averages. Only collects data when debug mode is enabled via set_mcp_debug. Use this to audit which MCP commands consume the most tokens and optimize your workflow accordingly.

example

cfa get_mcp_token_stats
