You approve every assistant
Signing in proves who you are; approving decides which assistant may spend your credits. This is the screen you will see:
What you can ask for
“Draw a labelled schematic of the mitochondrial electron transport chain for my review figure.”
“Here is my CSV of dose–response measurements. Plot a Nature-style box plot with individual points.”
“Make a CONSORT flow diagram for 400 screened, 320 randomized into two arms of 160, and export it as a PDF.”
“In this figure, change “Fig 1” to “Figure 1”.”
Questions
Do I need an API key?+
Claude, ChatGPT, Claude Code, Codex and Cursor can use OAuth. Clients that support only headers can use an API key.
I am already signed in. Why approve again?+
Approval is per assistant. It lets you see exactly which app may create figures with your credits, and remove it later.
Which plan do I need?+
Any account can connect and read its jobs and balance. Creating figures spends credits, so you need credits from a plan or a pack.
A figure is taking long. Should I ask again?+
No. Asking again creates and charges a new job. Ask the assistant to check the job with get_job; most finish within two minutes.
Can the assistant edit a figure it made?+
Yes: it can edit, upscale or convert an image, change a chart or flowchart it made, and replace text after detecting it.
The SciFig tools do not show up.+
Check that the connector is enabled for the chat, then reconnect it; in Claude Code run /mcp. If sign-in fails, disconnect the app under Settings → API Keys and connect again.
