The identity layer
your model is missing.

Every conversation with Claude starts cold. Yours doesn't have to. Install Noctara as an MCP server and Claude reads the person, not just the prompt.

What it does

The Noctara MCP server exposes one tool with seventeen modes. The four that matter to your model right now: mirror reads the user in ninety seconds, system_prompt returns a Claude-ready system addendum tuned to their compressed identity, identity_token mints a signed JWT for trusted apps to consume, scrub strips em-dashes and AI tells from any draft.

The result: Claude speaks to you as you. Your rhythm. Your half-truth. Your compliance lever. No memory feature. No chat history. A behavioral read of the body, not the language.

Install in three steps

Step 1 . get your read

Take the mirror, claim your identity.

Ninety seconds. Three sentences. Your word, your rhythm, your mark. Free.

Take the reading first if you don't have a Noctara identity yet. If you do, drop your email below.

Your Noctara email

Step 2 . copy your personal MCP config

One block. Pre-stamped with your identity.

This block becomes your claude_desktop_config.json (Claude Desktop), mcp.json (Cursor), or equivalent. Your email is embedded so every call from Claude is read as you.

{
  "mcpServers": {
    "noctara": {
      "command": "npx",
      "args": ["-y", "noctara-mcp-server"],
      "env": {
        "NOCTARA_API_BASE": "https://noctaracorp.com/api",
        "NOCTARA_USER_EMAIL": "your.email@here.com",
        "NOCTARA_CLIENT_ID": "openclaw"
      }
    }
  }
}

Step 3 . paste, restart, speak

Where it goes in each client.

Claude Desktop: Settings → Developer → Edit Config. Paste, save, restart Claude.

Claude Code: ~/.config/claude/mcp.json (or run claude mcp add noctara).

Cursor: Settings → MCP → Add Server. Paste the noctara block under mcpServers.

Cline: Extension settings → MCP Servers → Edit Configuration. Paste, save.

OpenClaw: ~/.openclaw/config/mcp.json. Paste, restart.

Try it

After install, in any of those clients, type:

Use the noctara tool. Mode: system_prompt. Email: your.email@here.com.
Then write me a paragraph about what you should do tomorrow.

The model will prepend the system addendum returned by Noctara. The paragraph will be in your rhythm, not the model's default. That's the layer.

Builders, the SDK is here

Building an agent on Claude SDK, Vercel AI SDK, LangChain, or your own stack? Skip the MCP and pull the SDK directly. Read the developer docs.

What this costs

Free for any active Noctara user. The MCP is a surface, not a SKU. If you don't have a Noctara identity yet, the reading at noctaracorp.com is the start. LUX is $33 a month, one tier, all MCP modes included: draft, ask, drift, narrative.

The architecture compounds.
