A setup guide for connecting Claude Code to the Unreal Engine 5 editor on Windows. It explains how to install the CodeFizz command-line tool, sign in, install the Unreal plugin, and check the connection.

It is for preparing an Unreal Engine project so Claude Code can control the editor through CodeFizz.

It removes the guesswork from installing and connecting the required tools, including what to do when the command or server is missing.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add aadeshrao123/Unreal-MCP --skill setup

Clone the repo

git clone --depth 1 https://github.com/aadeshrao123/Unreal-MCP

Made for: Claude Code.

Or install codefizz-editor-agent, the plugin that ships this one along with the rest of its 1 skill, 1 MCP server.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00052	$0.00461
Opus 5.5	$0.00021	$0.00184
Sonnet 5.5	$0.00010	$0.00092
Haiku 4.5	$0.00005	$0.00046

Security

Grade A, and why

setup scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Set up the CodeFizz Editor Agent

The plugin starts an MCP server with cfa mcp, so the cfa CLI must be installed first. Windows x64 only. Run each step, read its output, and stop on an error.

Check for the CLI: cfa --version. If it prints a version, go to step 3.
Install the CLI (no Node needed): powershell -c "irm https://codefizz.dev/install.ps1 | iex" It installs to %LOCALAPPDATA%\CodeFizz\bin\cfa.exe and adds that folder to the user PATH. Until a new terminal opens, call it by that full path.
Sign in: cfa login. It opens the browser. The user signs in with their CodeFizz account; a new account starts a free 3-day trial at https://codefizz.dev/pricing. Never type the user's password for them.
Install the Unreal plugin into an engine. List engines with cfa engines, then run cfa install-plugin "<engine folder>", for example cfa install-plugin "E:/Unreal/UE_5.8". Supported: UE 5.6, 5.7 and 5.8.
Install the full skill, which teaches every command and workflow: cfa skill install. Do not run cfa install claude; this plugin already provides the MCP server.
Open the project and check the connection: cfa launch "<path to .uproject>", then cfa health_check.
Ask the user to run /reload-plugins (or restart Claude Code) so the cfa MCP server connects.

When a step fails, run cfa doctor and show its output. Docs: https://codefizz.dev/docs/quick-start

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
