MCP Setup (AI Agents)

Add to your MCP client config (e.g. ~/.claude.json or Claude Desktop settings.json):

{
  "mcpServers": {
    "smartlead": {
      "command": "npx",
      "args": ["-y", "@bcharleson/smartlead-cli", "mcp"],
      "env": {
        "SMARTLEAD_API_KEY": "your_api_key_here"
      }
    }
  }
}

Or if installed globally:

{
  "mcpServers": {
    "smartlead": {
      "command": "smartlead",
      "args": ["mcp"],
      "env": {
        "SMARTLEAD_API_KEY": "your_api_key_here"
      }
    }
  }
}

All 41 CLI commands are available as MCP tools instantly. Tool names use snake_case: campaigns_list, leads_add_to_campaign, analytics_overview, etc.

Output

All commands output compact JSON to stdout by default — ready for piping and agent parsing.

# Compact JSON (default)
smartlead campaigns list
# → [{"id":123,"name":"Q1 Outreach","status":"ACTIVE",...}]

# Pretty-printed
smartlead campaigns list --pretty

# Filter fields
smartlead campaigns list --fields id,name,status

# Suppress output (exit code only)
smartlead campaigns create --name "Test" --quiet

Errors go to stderr as JSON: {"error":"...","code":"AUTH_ERROR"}

Exit codes: 0 success · 1 error
