TAPAC — MCP Server for B2B Contact Finding

Find & verify B2B contacts in real time. Scrapes company websites, Discord, and Telegram — then validates every email via SMTP. Built as a native MCP server, so Claude, ChatGPT, Cursor, and any AI agent can call it directly.

Install in one command:

uvx --from git+https://github.com/axelfreeman/tapac-mcp tapac-mcp

Then ask your agent: "Find 20 VP Sales at US SaaS companies with 50–500 employees."

Why TAPAC

Databases rot. 23% of contacts change jobs every year (ZoomInfo 2025), 40% of emails die within 2 years (NeverBounce). Buy a contact list and a quarter of it is stale before you send a single email.

TAPAC doesn't sell a database. It scrapes live and validates at request time:

	TAPAC	Static DBs (Apollo, ZoomInfo, Hunter)
Data source	Real-time scraping	Frozen snapshot
Bounce rate	2–5%	10–35%
Validation	SMTP, in the moment	None / after the fact
MCP / AI agents	✅ native	❌
Discord / Telegram	✅	❌
Pricing	Pay-per-use, $0.10–0.50/contact	$34–$15,000+/mo or /yr

Quick Start

1. Install

uvx --from git+https://github.com/axelfreeman/tapac-mcp tapac-mcp

Requires uv (one-liner installer: curl -LsSf https://astral.sh/uv/install.sh | sh).

Node instead of Python? The same server ships on npm — no Python toolchain needed, Node 18+:

npx -y @tapacapi/mcp

{
  "mcpServers": {
    "tapac": {
      "command": "npx",
      "args": ["-y", "@tapacapi/mcp"],
      "env": { "TAPAC_API_KEY": "your_key_here" }
    }
  }
}

Package: @tapacapi/mcp.

2. Wire into your agent

The same command + args work everywhere. Pick your agent:

Claude Desktop — claude_desktop_config.json:

{
  "mcpServers": {
    "tapac": {
      "command": "uvx",
      "args": ["--from", "git+https://github.com/axelfreeman/tapac-mcp", "tapac-mcp"]
    }
  }
}

Claude Code (terminal):

claude mcp add tapac -- uvx --from git+https://github.com/axelfreeman/tapac-mcp tapac-mcp

Codex (OpenAI) — ~/.codex/config.toml:

[mcp_servers.tapac]
command = "uvx"
args = ["--from", "git+https://github.com/axelfreeman/tapac-mcp", "tapac-mcp"]

Cursor — .cursor/mcp.json:

{
  "mcpServers": {
    "tapac": {
      "command": "uvx",
      "args": ["--from", "git+https://github.com/axelfreeman/tapac-mcp", "tapac-mcp"]
    }
  }
}

Windsurf — ~/.codeium/windsurf/mcp_config.json (same JSON as Cursor).

DeepSeek — the chat app doesn't register local MCP servers natively. Use DeepSeek through an MCP-capable client (Claude Code / Cursor with the DeepSeek API), or connect to the hosted endpoint https://tapacapi.com/mcp/sse.

3. Get your free API key

First run points you to https://tapacapi.com/get-key. Set it once:

export TAPAC_API_KEY=your_key_here

4. Ask for contacts

"Find 20 VP Sales at US SaaS companies with 50–500 employees, verify emails."

The agent asks for the criteria it needs, calls tapac_find_contacts, and returns verified contacts (name, title, company, email, source, verification status).

100 free searches, no credit card.

Status

Live. Install it, wire it into your agent, grab a free API key, and ask for contacts.

---

Demo script (no MCP wiring needed)

See the tool output shape instantly — run the tools directly without wiring the server:

uv run scripts/demo.py

It prints tapac_status() plus a sample tapac_find_contacts() call.

Skill (optional)

SKILL.md documents the TAPAC tools for any agent that loads skills. Install it with a symlink so git pull keeps it fresh:

ln -s "$PWD" ~/.agents/skills/tapac

Need this done for you?

What's in this repo is the free half of the work: sourcing, verification, and the volume a test actually needs to be readable. If you'd rather have that run against your own market:

• Engagement, scope and public pricing
• What actually ships in a done-for-you engagement
• Proof — what is live right now
• Appointment setting: the four checks a contact row passes before it is sent
