Lead411 Claude Plugin

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.

Requirements

Claude Code (CLI, desktop app, or IDE extension)
A Lead411 account (free trial or paid plan)

Installation

1. Install the plugin

In your terminal, from this directory:

claude mcp add --config mcp.json

Or 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"
      ]
    }
  }
}

2. Connect your Lead411 account (OAuth)

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.

3. Copy the skills

Place the .claude/skills/ directory from this repo into your project or home Claude config directory:

# For project-level (affects only this project)
cp -r .claude/ /your/project/.claude/

# For global use across all projects
cp -r .claude/ ~/.claude/

Example workflows

Find VP-level contacts in SaaS companies using Salesforce

/lead411:search VP of Sales, SaaS, uses Salesforce, 50-200 employees, California

Returns a shortlist of matching contacts with title, company, location, and contact availability. Suggests refinements like filtering to Directors only or narrowing by sub-industry.

Research a target account before outreach

/lead411:get-company acme.com

Returns the full company profile. Follow up with:

Also show me their tech stack and recent news

Now show me VPs and above at that company

Unlock and push a high-intent lead

/lead411:search Head of Engineering, Series B startups, New York

Unlock Jane Smith at Acme Corp

Push Jane to HubSpot

Credit confirmation is shown before unlock. CRM push preview is shown before sync.

Enrich a company list from a spreadsheet

Paste a list of domains or upload a CSV, then:

/lead411:enrich
acme.com, globex.com, initech.com, umbrella.com

Returns enriched firmographics for each company. Push matching accounts to CRM in one step.

Set up CRM integration

/lead411:configure-crm

Shows supported CRMs and your current connection status. Guides you to Lead411 Settings to authorize a new CRM if none is connected.

Credit usage

Unlock actions (/lead411:unlock) consume 1 Lead411 credit per record. The plugin always shows a confirmation prompt with the credit cost before proceeding. CRM pushes and searches do not consume credits.

Supported CRMs

Lead411 supports direct CRM sync with platforms including Salesforce, HubSpot, Pipedrive, and others. Run /lead411:configure-crm to see the full list of supported integrations.

Local development & testing

Test the plugin locally without installing it from a marketplace:

claude --plugin-dir ./lead411-mcp-plugin

Then try any skill:

/lead411:search VP of Sales in Austin
/lead411:get-company stripe.com

Run /reload-plugins inside Claude Code to pick up changes without restarting.

To test multiple plugins at once:

claude --plugin-dir ./lead411-mcp-plugin --plugin-dir ./other-plugin

Troubleshooting

OAuth prompt doesn't appear on first use Start a new Cowork session after installing the plugin and run any /lead411: skill — the OAuth screen should appear automatically.

"No CRM configured" error on push Run /lead411:configure-crm and follow the setup instructions to connect your CRM in Lead411 Settings.

Tool calls return no results Check that your Lead411 account has an active plan and that the MCP server is reachable: curl https://mcp.lead411.com/mcp
