CAUTION· startup only

Publisher claims: "The tools your AI needs to make your games. Turn prompts into production-ready game assets — animated characters with their weapons attached, seamless textures, terrain, VFX, HUDs — and shared game creation for the GripForge player, Unity, Godot and Unrea" Observed in sandbox: no network, touches nothing outside the project, writes no memory.

Coverage

Startup only; authenticated tool behavior not tested.
Tested
server startup over stdio (initialize sent) · every file read, file written and host contacted by what ran
Not tested
the tool list (the server exited before answering) · what the tools do when called with real credentials

What this means for the label: Caution here covers what ran. The server's tools were not exercised with a real credential, so nothing about their behavior is asserted; the credential summary below says what to do with that.

Before you give it your token

It will ask for
GRIPFORGE_API_KEYGRIPFORGE_PUBLICATION_TOKEN or --central-secretConfiguration, not credentials: CARGO_HOME, GODOT_BIN, GRIP_FORGE_HOME, GRIPFORGE_API_URL, GRIPFORGE_ASSETRIPPER_URL, GRIPFORGE_BLENDER_BIN, GRIPFORGE_CLI, GRIPFORGE_COLLISION_BIN, GRIPFORGE_COLLISION_WORK, GRIPFORGE_GAME_IMPORT_HOME, GRIPFORGE_GHIDRA_MCP_URL, GRIPFORGE_KIT_SDK, GRIPFORGE_LOD_BIN, GRIPFORGE_LOD_CACHE, GRIPFORGE_LOD_KIT, GRIPFORGE_LOD_KIT_URL, GRIPFORGE_LOD_WORK, GRIPFORGE_MCP_NO_UPDATE_CHECK, GRIPFORGE_MCP_REGISTRY, GRIPFORGE_MCP_UPDATE_FILE, LOCK_PATH
Where it talks to
no vendor host named in the codeAlso gripforge.ai, rustup.rs — not the publisher's domain; check what for before connecting.
What the honeypot saw
no credential files read · no network
What we could not test
the tool list (the server exited before answering) · what the tools do when called with real credentials

Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names gripforge.ai, rustup.rs as well as its own vendor. The guard injects GRIPFORGE_API_KEY, GRIPFORGE_PUBLICATION_TOKEN only into requests to the host you bind (and its subdomains) and refuses the rest.

Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios; startup only; authenticated tool behavior not tested) on 2026-11-13 and scored it 79/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Access to sensitive file paths; Access to sensitive file paths; Access to sensitive file paths. Summary: no network, touches nothing outside the project, writes no memory.
