LeadMCP
MCP server that gives your B2B outreach agent superpowers. LeadMCP lets your agent tap into Leadbay's rich knowledge base of companies, turning outreach activity from senseless spamming into meaningful connections.
Ask your agent for new leads, and it will pull highly qualified companies that score well against your target profile and meet your qualification criteria.
Everything is personalized—nothing to configure. Leadbay runs advanced AI agents on your website and leverages deep B2B sales expertise to optimize how leads are sourced for you.
Tell your agent which leads you want it to prospect, connect your communication channels, and it will source contacts from Leadbay and handle outreach on your behalf. Enjoy the outreach you no longer have to do.
How Leadbay thinks (mental model for your agent)
- Inbox, not a database. Each day your user logs back in, a fresh batch of leads is delivered. Batch size is paced by how many leads the user has actually acted on recently — some workflows produce a big stream of smaller prospects, others a narrow stream of bigger ones. Pulling more won't produce more; acting on leads does.
- Two scoring layers. Every lead ships with a basic
score (firmographic — already decent, usually correlates with AI). Roughly the top 10 of each batch are also AI-qualified (targeted web research + qualification questions → ai_agent_lead_score). Leads below the top 10 aren't worse — the system is saving resources. The agent can request deeper qualification (leadbay_bulk_qualify_leads) or contact enrichment (leadbay_enrich_titles) on any lead that looks worth it.
- Daily rhythm. The agent works best as a daily check-in: pull fresh leads, skim the auto-qualified top, deepen 1-3 promising ones, propose outreach, then log what actually got sent via
leadbay_report_outreach. If your host supports scheduling, set up a daily run.

Install in Claude (recommended)
The fastest way to get started is the one-click Claude extension.
1. Download the extension
👉 Download the latest LeadMCP for Claude (.dxt)
On the releases page, click the file ending in .dxt to download it.
2. Install it
Double-click the downloaded .dxt file. Claude opens and shows an install dialog — click Install, and you're done.
If the double-click doesn't open Claude, install it manually:
- Open Claude and go to your profile → Settings → Extensions.
- Open Advanced settings.
- Choose Install extension… and select the
.dxt file you downloaded.
3. Sign in
Claude will prompt you to connect Leadbay. Sign in with your Leadbay account and you're ready — just ask your agent for leads.
Using another assistant?
LeadMCP also works with Claude Code, Claude Desktop, Cursor, and Codex. The universal installer sets everything up for you and lets you sign in with Leadbay.
Requires Node.js 22+. Then run:
npx -y -p @leadbay/mcp@latest installer
It opens in your browser where you click Sign in with Leadbay, then pick which assistants to connect. Works on macOS, Windows, and Linux.
To uninstall, run the same installer with --uninstall:
npx -y -p @leadbay/mcp@latest installer --uninstall
It opens an uninstall window showing only the assistants that have Leadbay connected — pick the ones to remove and click Remove selected. It only removes Leadbay; your other settings and connections are left untouched.
For developers
Everything below is for contributors and anyone running LeadMCP from source or wiring it into automation.
Install a local version with the custom installer
To run your local checkout (instead of the published package), first build it from source:
pnpm install
pnpm prompts:build
pnpm -r build
Then point the installer at your freshly built version with --local:
pnpm --filter @leadbay/mcp installer -- --local
--local registers the MCP client(s) against the build in your working tree rather than @leadbay/mcp@latest. OAuth is handled automatically — you don't need to pass --oauth. The installer asks per-target before writing anything.
