Self-hosted decision memory for AI coding agents; warns before re-proposing a rejected approach.
Self-hosted decision memory for AI coding agents; warns before re-proposing a rejected approach. The robrain mcp server wraps that behind the Model Context Protocol, so an assistant can use it rather than through you.
RoBrain isn't just another memory layer — it's the brain that helps you and your agents make better decisions and avoid costly mistakes.
Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.
You will need 3 environment variables: ANTHROPIC_API_KEY, OPENAI_API_KEY, PERCEPTION_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Among the knowledge and memory options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. It is maintained by adelinamart; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against Robrain's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
