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 No outdated docs.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:

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.

<details> <summary>Manual setup (alternative)</summary>

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.
