AI
The assistant backend, its conversation limits, the API keys stored encrypted on this machine, and the local MCP server.
This page configures the Agentic panel's assistant. Most of it is a details panel, so the rows below are grouped by the same categories the app itself uses.
Backend
| Setting | What it does | Default | Choices |
|---|---|---|---|
| Backend | Which AI provider and connection method the Agentic panel uses. | Anthropic API (key) | Anthropic API (key), Claude Code (installed), OpenAI API (key), Codex (installed), Grok API (key), Grok Build (installed) |
The model and effort fields for each backend are not exposed on this page - use the model combo in the Agentic panel's own header instead.

API keys and the MCP token
Below the details panel, hand-built rows hold the actual secrets:
| Row | Behaviour |
|---|---|
| API key / API key (set) | Password box, shown only when Backend is Anthropic API. Hint text: sk-ant-... (stored encrypted on this machine). A Save button commits it. |
| OpenAI key / OpenAI key (set) | Password box, shown only when Backend is OpenAI API. Hint text: sk-... (stored encrypted on this machine). Save commits it. |
| Grok key / Grok key (set) | Password box, shown only when Backend is Grok API. Hint text: xai-... (stored encrypted on this machine). Save commits it. |
| MCP Bearer Token | Read-only, shown elided to 21 characters plus ..., or "(unavailable - see log)" if none exists yet. Tooltip: "Bearer token required by the local MCP server. Use Copy to get the full value for an external client's config." |
| Copy | Copies the full token to the clipboard. Tooltip: "Copy the MCP bearer token to the clipboard" |
| Regenerate | Mints a new token. Tooltip: "Generate a new MCP bearer token. Any client using the old token, including a running sidecar, must reconnect with the new one." |
All three provider keys are encrypted with Windows' own per-user encryption (DPAPI) before they touch disk, and are stored only on this machine - never as plain text.
