Overview
What is Frinus?
Frinus is an MCP server that bridges your MCP client (Claude Code, Cursor, Claude Desktop) with the Frinus platform (frinus.rdxsec.com.br), giving your agent long-term cognitive memory. It stores nothing locally and exposes 70 tools for memory, sessions, agents, knowledge hierarchy, orchestration, and training.
How to use Frinus?
You need a free Frinus account and an API key (sk-frinus-...). Add the server to your client via npx, setting the FRINUS_API_KEY environment variable. No installation is needed—npx fetches and runs the package on demand.

FAQ from Frinus
What is Frinus MCP?
It is a bridge between your MCP client and the Frinus hosted platform (https://frinus.rdxsec.com.br), providing long-term cognitive memory for AI agents.
How do I get an API key?
Log in to your Frinus account, go to Settings → API Keys, and create a new key. It will look like sk-frinus-... and is shown only once.
Do I need a Frinus account?
Yes. Sign up at https://frinus.rdxsec.com.br. The Free plan (R$0) includes 100 memories and 20 queries per day, no credit card required.
Where are my memories stored?
All memories live on the Frinus platform (hosted SaaS). The server stores nothing locally—every tool call is forwarded over HTTPS.
What are the system requirements?
You need an MCP-aware client (e.g., Claude Code, Cursor, Claude Desktop) and a Frinus account with an API key. The server runs via npx, so Node.js must be installed.
