Frequently asked questions
Avoid UI names that do not exist (「LLM Provider」, Settings 「MCP Servers」 tab, …).
Menu names follow the sidebar.
Getting started
How do I start LibrAgent?
- Install from Releases
- Settings → AI & Models → Provider API Keys → Save Changes
- Chat → assistant card → send from New Session
Details: 5-minute tutorial
What can I ask the agent to do?
Research, writing, code, files, browsing, scheduled work, and more. Available tools depend on the assistant and Extensions (MCP).
Can I create multiple assistants?
Yes — sidebar Assistants. Configure system prompt, default model, builtins/MCP. For a quick start, use Built-in Assistants on Chat (e.g. Libr Assistant, App Wizard).
Sessions
My session disappeared
Conversations are saved. Check History / Bookmarked, and recent sessions on Chat.
What happens when I delete a session?
History and that session’s context are removed. If there are sub-agents, choose delete with children vs keep. No restore. → Sessions, Sub-agents
Can I continue after quitting the app?
Yes — reopen from History or recent sessions.
Models · API keys
Which models are supported?
Anthropic, OpenAI, Google Gemini, Groq, Fireworks, Cerebras, OpenRouter, Ollama (local), and more.
Keys / default: Settings → AI & Models. Mid-session: Chat Provider/Model pickers change this session only. → Connecting models
Where are API keys stored?
In local app data. Manage under Provider API Keys, then Save Changes. Never paste keys into issues or chat.
Free / local models?
Provider free tiers (e.g. Gemini/Groq) or local endpoints such as Ollama via Custom OpenAI-compatible providers. Same Settings tab for key / Base URL.
Tools · Extensions · skills
What is MCP?
A protocol for external tools. There is no Settings 「MCP Servers」 tab. Use sidebar Extensions (/mcp-servers).
- Catalog: Extensions
- Manual: Custom MCP
Will the agent delete my files?
Risky actions usually follow approval (or YOLO) policy. Destructive deletes typically ask for confirmation. Tool calls appear in the session record.
Does it use a browser?
When the assistant has browser tools enabled, yes. Scope depends on the tool policy.
