Use Lead411's B2B contact and company intelligence directly inside Claude. Search for leads, enrich company accounts, unlock contact details, and push records to your CRM — all without leaving your conversation.
- Claude Code (CLI, desktop app, or IDE extension)
- A Lead411 account (free trial or paid plan)
In your terminal, from this directory:
claude mcp add --config mcp.jsonOr manually add the MCP server to your Claude Code config (~/.claude/claude_desktop_config.json or project .claude/settings.json):
{
"mcpServers": {
"lead411": {
"command": "npx",
"args": [
"mcp-remote",
"https://mcp.lead411.com/mcp",
"--allow-http",
"--header",
"X-MCP-UI-MODE: ui"
]
}
}
}The first time you use a Lead411 skill, mcp-remote will open your browser and prompt you to authorize Claude to access your Lead411 account. This is a one-time OAuth step — your token is stored locally and refreshed automatically.
No API keys to copy. No connector browser required.
