Supports synchronizing stored knowledge and persistent memory with Markdown files, allowing AI agents to manage and retrieve information in a structured document format.
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 No outdated docs.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
You chat — describe your coding standards, architecture decisions, client requirements, anything
UseCortex extracts — AI automatically organizes facts into structured topics
Your agent recalls — any MCP-compatible tool can query your knowledge instantly
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:
claude mcp add usecortex --transport url https://api.usecortex.net/mcp --header "Authorization: Bearer YOUR_API_KEY"That's it. Restart your AI coding agent and UseCortex tools are ready.
If you prefer to configure manually, add this to your MCP client config file:
{
"mcpServers": {
"usecortex": {
"type": "url",
"url": "https://api.usecortex.net/mcp",
"headers": {
"Authorization": "Bearer YOUR_API_KEY"
}
}
}
}Replace YOUR_API_KEY with the key generated in step 1.
