# 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/ ``` --- ## Skills | Skill | What it does | |---|---| | `/lead411:search` | Find contacts or companies by title, industry, location, tech stack, or hiring signals | | `/lead411:get-employee` | Get an enriched profile for a specific person | | `/lead411:get-company` | Get a full company profile: firmographics, tech stack, news, and jobs | | `/lead411:unlock` | Reveal gated contact details (email, direct dial) — consumes 1 credit | | `/lead411:push-to-crm` | Sync contacts or companies to your connected CRM | | `/lead411:configure-crm` | Check or set up your Lead411 CRM integration | | `/lead411:enrich` | Batch enrich a CSV or list of company domains with Lead411 data | --- ## 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` --- ## Resources - [Lead411 website](https://www.lead411.com) - [Lead411 API docs](https://www.lead411.com/api) - [Claude Code docs](https://docs.anthropic.com/claude-code) - [Claude Plugin docs](https://code.claude.com/docs/en/plugins)
