TAPAC — MCP Server for B2B Contact Finding

License: MIT Python 3.10+ MCP native Lint pre-commit axelfreeman/tapac-mcp MCP server

skills.sh

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:

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.

Find and verify B2B contacts.

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

TDQS

A4/5.0

Scored across 2 tools

Disambiguation5/5

The two tools serve completely distinct purposes: one checks server status, the other finds contacts. There is no overlap or ambiguity.

Naming Consistency5/5

Both tools follow a consistent snake_case pattern with the prefix 'tapac_', one describing a state (status) and the other an action (find_contacts). The naming is uniform.

Tool Count3/5

With only two tools, the server feels thin for a contact-finding service, but each tool is clearly defined and serves a necessary function. It is borderline but not excessive.

Completeness4/5

The server covers the core operation of finding and verifying contacts with extensive filtering, plus a status check. Minor gaps like retrieving a specific contact by ID are absent, but the main workflow is complete.
