I built 2 MCP servers that make Claude a financial analyst and SEO auditor

If you use Claude Code or Claude Desktop, you probably know about MCP (Model Context Protocol) — the standard for giving AI agents access to external tools. There are 17,000+ MCP servers out there, but most are basic API wrappers.

I built two that try to go beyond wrapping: they add intelligence on top of the data.

FinanceKit MCP — Financial Market Intelligence

12 tools. The core value is the technical analysis engine — it doesn't just return raw data from Yahoo Finance. It calculates 10 technical indicators, detects patterns, and gives you a plain-English verdict.

Ask Claude: "Run technical analysis on NVDA"

You get:

Overall bias: STRONGLY BULLISH (quantified: 3.0 bullish vs 0.5 bearish signals)
RSI, MACD, Bollinger Bands, SMA(20/50/200), EMA, ADX, Stochastic, ATR, OBV
Pattern detection: Golden Cross, Death Cross, overbought/oversold
7 detailed signals like: "MACD bullish — line above signal, both positive. Strong upward momentum."

Other tools: stock quotes, crypto prices (CoinGecko), market overview (S&P 500, NASDAQ, DOW, VIX, top movers), multi-asset comparison with Sharpe ratios and drawdown, portfolio analysis with sector breakdown.

SiteAudit MCP — Instant Website Audits

8 tools. Give it any URL and it runs 20+ SEO checks, analyzes security headers, verifies SSL certificates, measures performance, and can compare multiple sites.

Ask Claude: "Audit stripe.com"

You get:

Overall: 92/100 (Grade A) — SEO: 94, Performance: 90, Security: 90
Specific issues: "Title too long (66 chars)", "46/75 images missing alt text"
SSL certificate status and expiration
Performance: 66ms response, gzip compression, no redirects

The compare_sites tool is the killer feature for competitive analysis — compare your site against 3 competitors in one command.

Also includes Lighthouse scores and Core Web Vitals via Google PageSpeed Insights API, and broken link detection with concurrent checking.

How to install

⭐ Recommended: MCPize (zero setup, free tier)

The fastest path. No terminal, no Python setup, no config wrestling. Works immediately in Claude Desktop, Cursor, Windsurf, and Claude Code:

👉 Install FinanceKit on MCPize — Free 100 calls/mo
👉 Install SiteAudit on MCPize — Free 100 audits/mo

Or add directly to your MCP config:

{
  "mcpServers": {
    "financekit": { "url": "https://financekit-mcp.mcpize.run/mcp" },
    "siteaudit": { "url": "https://siteaudit-mcp.mcpize.run/mcp" }
  }
}

Pricing tiers

FinanceKit: Free ($0) → Hobby ($9) → Pro ($29) → Team ($79) → Business ($179) → Enterprise ($499)

SiteAudit: Free ($0) → Hobby ($7) → Pro ($19) → Agency ($49) → Agency Plus ($119) → Enterprise ($349)

Bundle: Pro Combo (both) = $39/mo (save 19%)

Annual plans get 2 months free.

Advanced: self-hosted (developers)

Prefer to run locally? Both are MIT-licensed and free to self-host — you manage updates and rate limits:

Self-hosted install

# Claude Code CLI
claude mcp add financekit -- uvx --from financekit-mcp financekit
claude mcp add siteaudit -- uvx --from siteaudit-mcp siteaudit

# Or Claude Desktop / Cursor / Windsurf config
{
  "mcpServers": {
    "financekit": {
      "command": "uvx",
      "args": ["--from", "financekit-mcp", "financekit"]
    },
    "siteaudit": {
      "command": "uvx",
      "args": ["--from", "siteaudit-mcp", "siteaudit"]
    }
  }
}

Also on Smithery (one-click install) and PyPI.

For most users, MCPize is the better choice — zero setup, always up-to-date, no infrastructure to manage.

Tech stack

FastMCP 3.2 for the MCP server framework
yfinance + CoinGecko API for financial data
ta library for technical analysis calculations
BeautifulSoup for HTML parsing (SiteAudit)
Google PageSpeed Insights API for Lighthouse (free, 25K calls/day)
TTL-based caching to minimize API calls

Both are open source (MIT) and now listed on the Official MCP Registry (io.github.vdalhambra/financekit-mcp and siteaudit-mcp):

What's next

I'm working on v1.2 with premium tools for Pro tier and above:

FinanceKit: smart alerts, backtesting, options chains, news sentiment, insider trading, sector rotation, risk metrics
SiteAudit: extended 50+ SEO checks, competitor gap analysis, scheduled audits, white-label PDF reports, full-site crawler, WCAG accessibility checks
