Second Brain

Talk to Tom Osborne's voice-cloned AI agent from inside Claude Desktop, Claude Code, Cursor, Cline, or any Model Context Protocol–compatible client.

Built on Tom's 100-question interview corpus, 15 years of operator memory, and 21,000+ curated marketing knowledge-base articles across 17 verticals (paid, content, SEO, sales, leadership, PR, ads, design, HR, finance, legal, local, marketing fundamentals, business strategy, creator, community, entrepreneurship).

What it does

Adds one tool to your MCP client:

ask_tom(question: string) → Tom's answer in his voice, with KB chunks retrieved

When called, it POSTs your question to https://tomosborne.me/api/cmo/chat along with your configured email, and returns Tom's reply. The same pipeline that powers tomosborne.me/cmo — same retrieval, same security gate, same voice.

Installation

1. Install via npm

npm install -g @tom-osborne/second-brain-mcp

(Or run via npx @tom-osborne/second-brain-mcp if you prefer not to install globally.)

2. Add to your MCP client config

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "second-brain": {
      "command": "npx",
      "args": ["-y", "@tom-osborne/second-brain-mcp"],
      "env": {
        "MCP_TOM_EMAIL": "[email protected]"
      }
    }
  }
}

Restart Claude Desktop. The ask_tom tool will appear in the MCP tools panel.

Claude Code

Add to your project's .mcp.json:

{
  "mcpServers": {
    "second-brain": {
      "command": "npx",
      "args": ["-y", "@tom-osborne/second-brain-mcp"],
      "env": {
        "MCP_TOM_EMAIL": "[email protected]"
      }
    }
  }
}

Or via the CLI:

claude mcp add second-brain -e [email protected] -- npx -y @tom-osborne/second-brain-mcp

Cursor / Cline / other MCP clients

Use the same shape — point at npx @tom-osborne/second-brain-mcp with MCP_TOM_EMAIL in env.

Usage

Once installed, in any MCP-aware chat:

Use ask_tom: how do I get to my first 100 customers as a DTC brand?

The tool returns Tom's answer in his voice, drawing on his interview corpus + the 21k-article KB.

Quotas

• Free tier: 5 questions per day per email (rate-limited at the API)
• Coffee unlock: +20 questions/day + faster replies + voice replies — buy at https://tomosborne.me/cmo
• Loyalty: every 6 coffees = 24h/7d/30d VIP unlock (unlimited premium)

If you hit the cap, the tool returns a clear "go upgrade" message rather than failing silently.

Environment variables

Variable	Required	Default	Purpose
MCP_TOM_EMAIL	Yes	—	Your email — used for daily quota tracking. Must be a real email.
MCP_TOM_API_KEY	No	—	Optional API key for higher-tier access (gate is server-side; ignored if not configured)
TOM_API_BASE	No	https://tomosborne.me	Override the API base (only useful for dev/testing)

Privacy

• Your questions are sent to tomosborne.me/api/cmo/chat over HTTPS
• Email is stored against your daily quota counter; never shared, never sold
• The Pages Function applies the same security filter set as the public /cmo chat (no wallet addresses, API keys, or PII in responses)
• Source: tomosborne.me is open-source-ish in spirit — DM Tom if you want to peek under the hood

Local development

git clone https://github.com/DegenDoes/second-brain-mcp.git
cd second-brain-mcp
npm install
[email protected] npm run dev   # tsx in watch mode

Test it via the MCP Inspector:

npx @modelcontextprotocol/inspector npx -y @tom-osborne/second-brain-mcp
