@vextlabs/theron-mcp

Call JUWEL from any AI tool. An MCP server that gives any MCP client — Claude Desktop, Cursor, an IDE, an agent runtime — direct access to JUWEL, Vext Labs' council of domain specialists over one auditable base.

Four tools:

| Tool | What it does | |------|--------------| | theron_ask | Ask JUWEL (optionally a specialist lane) a question — coding, legal drafting, admin, medical literature, data analysis, design, deep research. | | theron_specialists | List the specialist lanes you can target. | | theron_commission | Commission a real work product (doc, deck, sheet, code, design, campaign) via JUWEL's deliverable pipeline; returns a tracking URL. The finished artifact carries an offline-verifiable receipt. | | theron_verify_receipt | Fetch the signed Merkle proof for any JUWEL/STOA receipt so you can verify what JUWEL did offline, trusting no one. |

Install

Public chat needs no token. To commission deliverables to your account, set THERON_TOKEN (create one at https://tryvext.com/api-keys).

Claude Desktop

Add to claude_desktop_config.json → mcpServers:

{
  "mcpServers": {
    "theron": {
      "command": "npx",
      "args": ["-y", "@vextlabs/theron-mcp"],
      "env": { "THERON_TOKEN": "vxk_live_..." }
    }
  }
}

Cursor

In ~/.cursor/mcp.json (or Settings → MCP):

{
  "mcpServers": {
    "theron": { "command": "npx", "args": ["-y", "@vextlabs/theron-mcp"], "env": { "THERON_TOKEN": "vxk_live_..." } }
  }
}

Then ask your assistant things like "Use theron to draft a mutual NDA" or "Ask theron-analyst to model this churn data" — the model will call theron_ask / theron_commission for you.

Honesty

The specialist handles are persona surfaces over the live JUWEL base today; deeper per-specialist weights are on the roadmap. Legal/medical lanes assist with drafting and literature — they are not legal or medical advice; review with a licensed professional.

Config

| Env | Default | Purpose | |-----|---------|---------| | THERON_TOKEN | — | Optional bearer; required for account-scoped deliverables. | | THERON_BASE_URL | https://tryvext.com | API base. |
