mcp-tools-bundle 1.2.0

3 zero-dependency MCP servers in pure Python — CDP scraper, crypto monitor, email sender

MCP Tools Bundle — 3 Zero-Dependency MCP Servers in Pure Python

Three production-ready MCP (Model Context Protocol) servers for AI agents. Zero pip dependencies. Pure Python stdlib. 105 tests passing.

Servers

Server	Tools	Tests	Repo
mcp-cdp-scraper	12	38	github.com/aaameobius-crypto/mcp-tools-bundle
mcp-crypto-monitor	10	30	github.com/aaameobius-crypto/mcp-tools-bundle
mcp-email-sender	8	37	github.com/aaameobius-crypto/mcp-tools-bundle
Total	30	105

Why Zero Dependencies?

Every MCP server here uses only Python's standard library — no pip installs, no npm, no Playwright, no Selenium, no requests. Just Python 3.10+ and an internet connection.

This means:

• Docker images stay tiny (~50MB vs 250MB+ with Playwright)
• No supply chain risk — no third-party packages to audit
• Fast CI — no dependency resolution, no cache invalidation
• Portable — works in any Python environment without venv setup

Quick Install

# Clone all three
git clone https://github.com/aaameobius-crypto/mcp-tools-bundle.git
git clone https://github.com/aaameobius-crypto/mcp-tools-bundle.git
git clone https://github.com/aaameobius-crypto/mcp-tools-bundle.git

# No pip install needed — zero dependencies!
# Just run directly:
python mcp-cdp-scraper/src/server.py --manifest
python mcp-crypto-monitor/src/server.py --manifest
python mcp-email-sender/src/server.py --manifest

mcp-cdp-scraper — Web Scraping via Chrome DevTools Protocol

12 tools: scrape_page, extract_text, extract_links, extract_images, extract_table, fill_form, click_element, screenshot, get_html, wait_for, scroll_to, list_tabs

Connects to any Chrome/Chromium instance via raw WebSocket CDP. React/Vue compatible form filling using native setters + synthetic events. No Playwright, no Selenium.

from src.server import MCPCDPScraperServer

server = MCPCDPScraperServer()
result = server.handle_tool_call("scrape_page", {"url": "https://news.ycombinator.com"})

mcp-crypto-monitor — Crypto Wallet & Price Monitoring

10 tools: get_btc_balance, get_eth_balance, get_erc20_balance, get_btc_transactions, get_price, get_price_binance, get_portfolio_value, get_gas_price, get_fear_greed, monitor_address

Uses free public APIs only — Blockchain.info, Etherscan, CoinGecko, Binance, alternative.me. No API keys required.

from src.server import MCPCryptoMonitorServer

server = MCPCryptoMonitorServer()
result = server.handle_tool_call("get_portfolio_value", {"holdings": {"BTC": 0.5, "ETH": 10.0}})

mcp-email-sender — Email Validation & SMTP

8 tools: validate_email, validate_email_batch, check_mx_records, is_disposable, is_role_based, send_email, send_email_batch, test_smtp_connection

Email validation (format, disposable, role-based, MX records) + SMTP sending (TLS/SSL, CC/BCC, batch). Pure stdlib (smtplib, email, re, socket).

from src.server import MCPEmailServer

server = MCPEmailServer()
result = server.handle_tool_call("validate_email", {"email": "[e-mail]"})

Architecture

Each server follows the same pattern:

MCP Client (Claude / Hermes / any)
    │  JSON-RPC over STDIO
    ▼
MCPServer (src/server.py)
    │  Tool dispatch + schema
    ▼
Engine (src/<engine>.py)
    │  Zero-dep business logic
    ▼
External API / Chrome / SMTP

Testing

# Run all tests
cd mcp-cdp-scraper && python -m pytest tests/ -q    # 38 passed
cd mcp-crypto-monitor && python -m pytest tests/ -q  # 30 passed
cd mcp-email-sender && python -m pytest tests/ -q    # 37 passed
# Total: 105 tests, all passing
