How they talk to each other
cu.yambr.com is not an MCP endpoint. It hosts sandboxes and serves artifact URLs. The public MCP endpoint is https://api.yambr.com/mcp/computer_use — call that with your Yambr key. See cu.yambr.com.When to use what
API keys
Sign in with GitHub/Google, get approved, manage up to five keys with live spend.

Managed vs self-hosted
| Managed (Yambr) | Self-hosted | |
|---|---|---|
| Where it runs | *.yambr.com | Your Docker host |
| How you get access | Key from app.yambr.com after OAuth + approval | Clone repo, docker compose up |
| Cost | $10 / 30-day default budget; per-key max_budget | Infra cost only |
| Model provider | Bring your own (OpenAI, Anthropic, LiteLLM-self-hosted, …) | Bring your own OPENAI_API_KEY in .env |
| Public surface | MCP only (api.yambr.com/mcp/computer_use) + chat.yambr.com + artifacts | Full HTTP API on localhost:8081 — you control auth |
| File URLs | https://cu.yambr.com/files/... | http://localhost:8081/files/... |
| Updates | Automatic | git pull && docker compose build |
| Good for | Fastest start, most teams | Air-gapped, custom skills, full control |
