The Brain

Connect Claude to 20 years of teaching innovation.

Every method answer Larry gives comes from the Brain: a live map of 181 thinking methods, which one fits this moment, and how they chain, calibrated by what actually worked for 100+ real ventures. Your key keeps that connection alive, and answers say where they came from.

Free 30-day trial. No credit card. Key delivered instantly.

Three steps

From sign-in to Brain-connected.

1

Sign in

One-click Google. Your 30-day trial starts instantly.

2

Get the key

Unique API key provisioned automatically. Copy from your dashboard.

3

Connect

One config entry. Brain intelligence activates immediately.

What the key changes

Grounded answers, or an honest refusal.

With a working key

Larry's method answers come from the teaching graph and say so, with a source line. Chaining, calibrated grading against 100+ real projects, and cross-domain patterns all ride on the same connection.

Without one

Larry tells you plainly the Brain is disconnected and refuses to invent method answers, instead of serving a look-alike. Your rooms, files, and local graph keep working the whole time. A refusal is the product being honest, not broken.

Plans and prices live on one page: see pricing. The trial is free, no credit card.

Setup

Got your key? Connect in 60 seconds.

Two paths, depending on where you run Claude.

CLIClaude Code (terminal)

Run this

/mos:setup brain
# Larry asks for your API key
# Paste it when prompted
# Done. Brain is connected.

Or manually: add MINDRIAN_BRAIN_KEY=your-key to your project's .env.

DTClaude Desktop / Cowork

claude_desktop_config.json

{
  "mcpServers": {
    "mindrian-brain": {
      "url": "https://mindrian-brain.onrender.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Replace YOUR_API_KEY with the key from your dashboard. Restart Claude Desktop.

Troubleshooting

If something feels off.

Getting 'RESOURCE_EXHAUSTED' or a Pinecone quota error?

Run rm -f .mcp.json then restart. Your rooms, files, and local graph are untouched; while the Brain is unreachable, Larry says so and holds off on method answers instead of improvising.

Getting '401 Invalid API key'?

Check the key. If expired, sign in again to verify trial status.

Brain server slow on first request (30-60s)?

The Brain server sleeps after 15 minutes idle. The first call wakes it. Subsequent calls are fast.

Old config with neo4j-brain / pinecone-brain entries?

Delete .mcp.json and use /mos:setup brain instead. The old direct-database pattern is deprecated.
