Installation, client compatibility and comprehensive security have not been independently audited. Authentication and access depend on the configured services.
Upstream credential and permission scopes must be validated before runtime use.

Write actions/tool inventory not confirmed against exact tool documentation; listed action classes remain illustrative or context-dependent. Empty inventory does not establish read-only.
Some integration/runtime instructions are not confirmed from a first-party install guide and therefore intentionally omitted.

Warning

Initializer mutates Unreal project/client setup; run in intended project and review changes.
Manual .uproject path must be replaced with user actual project path.
Exact vendor-specific credential revoke procedure not established from checked official Setup documentation; may be external or not applicable. Do not invent.
Auto-detects .uproject, deploys C++ bridge, enables UE plugins and configures selected MCP client; inspect proposed changes.
publisher README config shape Replace the supplied credential/path placeholders privately; use only the named configuration schema.
This is an INTERACTIVE INITIALIZER that changes the project bridge/plugin and MCP client configuration; it is not a stdio server process.
MCP100 client-scope note: this Claude Code CLI example applies only to that client and the exact registered name in the command. Desktop, Cursor and other clients use their own configuration; do not run it for a differently named entry.

Check connection
Suggested check
Reopen Unreal Editor and check exposed MCP tools/bridge. Do not modify actors merely to verify.
Remove / uninstall / revoke
MCP100 setup guide
Remove MCP host entry and UE_MCP_Bridge plugin from this UE project only if no longer required; consult project wizard docs for cleanup.
MCP100 client-scope guidance: each CLI removal example targets only its named client and exact registered entry. Package names, Desktop/Cursor configuration keys and Codex/Claude registration names may differ; use the entry you actually registered. Client removal does not revoke provider credentials.

FAQ

Based on reviewed evidence as of 2026-10-10T03:38:00Z. Watchlist tracking is not a recommendation or a security certification.

Which tasks are documented for this implementation?

The reviewed tasks include: Unreal Engine development and project operations.

What setup and authentication are documented?

A complete connection procedure is not verified. Client notes: Installation command omitted unless verified or clearly package-specific; do not infer npx/uvx entrypoints. These facts do not supply missing installation commands, credentials or a verified authentication procedure. Authentication: Refer to first-party setup documentation; do not infer authorization from package existence.

Can it modify data or perform write operations?

Not verified. The available evidence does not establish the complete write authority. The partial inventory lists: create/change/delete project objects. Recorded permission context: Unreal Engine project/world modifications may affect assets; work on a copy and restrict agent privileges.

What data-handling boundary should I consider?

Unreal Editor state and local project files Recorded sensitive-access context: Unreal Editor state and local project files.

What limitations and risks should I check before use?

Unreal Engine project/world modifications may affect assets; work on a copy and restrict agent privileges. Some integration/runtime instructions are not confirmed from a first-party install guide and therefore intentionally omitted. Exact GitHub pushed_at 2026-10-09T19:17:06Z. Public tracking suitability is not an installation safety audit. Upstream credential and permission scopes must be validated before runtime use.
