Leadbay
Connects Claude to your Leadbay account for AI-driven B2B lead discovery and outreach prep. Pull daily scored leads, run deep qualification passes, enrich contact titles, and log outreach activity without leaving your agent workflow. Leadbay treats leads like an inbox, not a database: fresh batches arrive daily, paced by your actual follow-through. The top slice gets auto-qualified; the rest can be deepened on demand. Tools cover read-only ops like research cards and campaign metrics, plus write actions for bulk qualification, audience tuning, and activity logging. Best used as a daily rhythm: pull leads, qualify promising ones, prep outreach, then report what you sent.

Readme
Leadbay MCP
Leadbay MCP
Leadbay MCP connects your AI assistant to your Leadbay account, so you can work your leads by simply asking.
Pull leads, qualify them, draft outreach, and log activity — in plain language. Your assistant acts on your real Leadbay data, with your permissions, just as you would in the app.
Everything is personalized — nothing to configure. Leadbay runs advanced AI on your website and market data to source and score leads against your target profile, so outreach becomes meaningful connection instead of senseless spamming.
Tell your assistant which leads to prospect, connect your channels, and it sources contacts from Leadbay and handles outreach on your behalf. Enjoy the outreach you no longer have to do.
MCP stands for Model Context Protocol — an open standard that lets AI assistants like Claude securely connect to external tools and data. This server is open source and lives at github.com/leadbay/mcp.
