Lead411
Pull B2B company lists, search firms, and enrich contacts from Lead411 while researching who to sell to.
Overview
Lead411 MCP is an Idea-phase MCP server that provides B2B company search, lead generation, and contact enrichment via Lead411’s hosted SSE endpoint.
What is this MCP server?
- Remote SSE MCP at https://mcp.lead411.com
- B2B lead generation, company search, and contact enrichment
- Authenticates with required secret header X-API-KEY
- Registry version 1.0.0 with website lead411.com
- No local npm package—hosted MCP endpoint
- Remote SSE URL https://mcp.lead411.com
What problem does it solve?
Indie B2B builders stall on ICP research because company and contact data lives in a separate product from their coding agent.
Who is it for?
Solo SaaS founders doing outbound validation, niche B2B tools, or services who already budget for Lead411.
Skip if: B2C consumer apps, builders without a Lead411 subscription/API key, or teams that forbid third-party contact enrichment.
What do I get? / Deliverables
After you add the remote MCP with X-API-KEY, your agent can query Lead411 for companies and enriched contacts inside the same research session.
- Agent-queryable B2B company search results
- Contact enrichment payloads from Lead411 tools
- Faster ICP and outbound list building without custom scrapers

Journey fit
Canonical shelf is Idea because Lead411 MCP is primarily for discovering and qualifying B2B audiences before you commit to a full build. Audience subphase matches company search and contact enrichment used to define ICP and outbound targets early in the journey.
How it compares
Hosted B2B data MCP, not a CRM replacement or generic web-scraping skill.
