B2B Contact Mining

Find and verify B2B business contacts without buying a database. The agent mines fresh leads from Google, Telegram, and Discord — then SMTP-validates every email before it goes into a cold-outreach list. Free, self-hosted, no vendor lock-in.

When to Use

• The user wants to find B2B business emails or phone numbers.
• Building a cold-outreach / lead-gen list from scratch.
• Replacing Apollo, ZoomInfo, Hunter, or a resold contact database.
• Mining leads from Telegram channels or Discord communities.
• Verifying that a list of emails is real before sending.

Don't use for: buying or reselling contact data, or non-B2B consumer leads.

Prerequisites

• The agent's own web-search tool for Google / Telegram / Discord.
• The SMTP validator needs dnspython — install deps from requirements.txt (see README).
• Optional: TAPAC API key (https://tapacapi.com/get-key) to automate the pipeline as an MCP server.
