# 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](https://claude.ai/code) (CLI, desktop app, or IDE extension)
- A [Lead411 account](https://www.lead411.com) (free trial or paid plan)
---
## Installation
### 1. Install the plugin
In your terminal, from this directory:
```bash
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`):
```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:
```bash
# 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:
```bash
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:
```bash
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`
