TC Connector

Teach Charlie AI MCP Connector — bridges your Teach Charlie workflows to local AI agents like OpenClaw via the Model Context Protocol.

How It Works

OpenClaw Agent (local)
    | stdio (MCP protocol)
TC Connector (this package)
    | HTTPS
Teach Charlie API (remote)
    | internal
Langflow (executes workflow)

1. You enable workflows as "skills" in Teach Charlie
2. TC Connector fetches those skills and exposes them as MCP tools
3. Your local AI agent (OpenClaw, Claude Code, etc.) can call those tools
4. The connector routes calls to Teach Charlie, which runs the workflow in Langflow

Quick Start

Option A: Interactive Setup

npx tc-connector --setup

This walks you through entering your token, verifies it, and saves config to ~/.tc-connector/config.json.

Option B: Manual Setup

1. Generate an MCP Token

Go to Settings > OpenClaw Connection in your Teach Charlie dashboard and click Generate MCP Token.

2. Add to OpenClaw

Add this to your .mcp.json (or OpenClaw MCP config):

{
  "mcpServers": {
    "teach-charlie": {
      "command": "npx",
      "args": ["tc-connector", "--token", "tc_YOUR_TOKEN_HERE"]
    }
  }
}

Or if installed globally:

{
  "mcpServers": {
    "teach-charlie": {
      "command": "tc-connector",
      "args": ["--token", "tc_YOUR_TOKEN_HERE"]
    }
  }
}

3. Restart OpenClaw

Restart OpenClaw and your Teach Charlie workflow skills will appear as available tools.

Commands

Check Status

Verify your token and see available tools:

npx tc-connector --status
