UseCortex MCP is a Model Context Protocol server that gives AI coding agents persistent memory. Your agent can read knowledge you've stored and write new discoveries back — all through a single encrypted endpoint.
No context window limits. No copy-pasting. No outdated docs. Your AI remembers everything.
How It Works
1. **You chat** — describe your coding standards, architecture decisions, client requirements, anything
2. **UseCortex extracts** — AI automatically organizes facts into structured topics
3. **Your agent recalls** — any MCP-compatible tool can query your knowledge instantly
4. **Knowledge grows** — your agent can push new discoveries back, so your knowledge base stays current
Features
- **Two-way knowledge flow** — read context into projects, write discoveries back
- **Works with any MCP client** — compatible with any AI coding agent that supports the Model Context Protocol
- **Encrypted at rest** — AES-256 encryption with per-user keys
- **No vendor lock-in** — your knowledge works across every AI tool
- **Structured by topic** — knowledge auto-organized, not dumped in one pile
Quick Start
Prerequisites
- A free UseCortex account
- An MCP-compatible AI coding agent
1. Generate an API key
Sign up at usecortex.net, then navigate to **Settings → API Keys → Generate**.
> **Note:** Copy the key immediately after generation. It will not be shown again.
2. Install (one command)
Run this in your terminal — replace YOUR_API_KEY with the key from step 1:
That's it. Restart your AI coding agent and UseCortex tools are ready.
Manual setup (alternative)
If you prefer to configure manually, add this to your MCP client config file:
Replace YOUR_API_KEY with the key generated in step 1.
