Apache-2.0 library, REST server and MCP server, all self-hostable, with local models and no LLM key since 1.6.0. No status page, rate limits, SLA or SOC 2 for Cloud, and Cloud runs in AWS us-east-1 with no EU region.
Context Mode Engine

Before you call either
Cognee
- Use remember, recall and forget. The older cognify, search and delete MCP tools are gone
- Always include /api/v1 in REST paths
- Check cognify_status before querying data you added with background=true
- Never pass everything=true to forget unless you mean to wipe all of the user's memory
- Set a client timeout on Cloud calls and treat HTTP 402 as an empty balance, since an empty balance has also shown up as hangs
Context Mode Engine
- Choose the installation guide for the exact coding client.
- Check host permissions before enabling code execution.
- Review the Elastic licence before hosting Engine for others.
