Client support and limits
We’d rather say this here than surprise you in a chat. Which apps we support is on compatibility.
Grok Build CLI login on Safari
Grok Build CLI tries to complete browser sign-in through a local page. Safari can block that. We send an access key instead — that’s the supported path, not a workaround. Don’t switch your default browser for us.
Don’t reconnect if it’s working
Grok Bot and Grok web/iOS may show a reconnect screen even while tools work. Keep a working connection. In Cursor or Grok Build CLI, a missing access key needs the key restored in that app’s environment. See setup guidance for each client.
Claude.ai can connect, but not open file links
Ask Claude to read from the vault. Don’t tell it to open a download URL — it will refuse. Small text and extracted PDF text can be returned directly to Claude. Pictures, audio, and larger files use a separate read option with size limits; large files may need to be read in parts. Supported does not mean every format works without limits.
ChatGPT custom MCP access varies by plan and account
Artifactum works with ChatGPT Plus. Add the custom app on ChatGPT web, then select it in a conversation to save and find files. Managed workspaces may require an administrator to enable Developer mode or approve the app. Follow the current setup steps. A generic sign-in error often means the client ID was mistyped — copy and paste it from the setup email. If a model ignores the vault, write hello@artifactum.ai.
Claude Code, Desktop, and Codex
Same vault address as Claude.ai and ChatGPT. Point Claude Code or Desktop at your configured vault address using the setup provided for that app. Codex uses that address plus your access key. ChatGPT custom MCP setup starts on the web.
Hermes Agent
Hermes Agent — verified, working beautifully, and fully supported.
Hermes Agent CLI (v0.21.1+) connects via native Model Context Protocol (MCP) using
hermes mcp add or config.yaml.
Full Content Object storage, retrieval, and delete workflows are verified across supported
model backends. Setup guide: Connect Hermes.
Your address is private
Hosted signup is on plans. We email the vault address. This site does not publish it.
