Built 2 production MCP servers with FastMCP: FinanceKit (stock analysis) & SiteAudit (SEO audits)

[vdalhambra]

Wanted to share two MCP servers I built using FastMCP 3.2 — both are live on PyPI, MCPize, and Smithery.

FinanceKit MCP — Financial Market Intelligence

12 tools for stock analysis, crypto data, and portfolio management. The main value-add over raw API wrappers is the technical analysis engine — it calculates 10 indicators (RSI, MACD, Bollinger Bands, SMA including 200-day, ADX, Stochastic, ATR, OBV), detects patterns like Golden Cross/Death Cross, and returns an overall bullish/bearish bias with a quantified signal score.

Also includes a market_overview tool that shows major indices (S&P, NASDAQ, DOW), VIX, and top gainers/losers.

SiteAudit MCP — Instant Website Audits

8 tools. Give it any URL and get a full SEO audit (20+ checks), security headers analysis, Lighthouse scores via PageSpeed API, broken link detection, and multi-site comparison.

FastMCP experience

FastMCP made this really smooth — the @mcp.tool decorator pattern is clean, async/sync support just works, and the Client class made testing straightforward. The transport auto-detection (stdio locally, HTTP in cloud via PORT env) was key for deploying to MCPize.

One tip for anyone deploying to cloud: add sys.path.insert(0, str(Path(__file__).resolve().parent.parent)) at the top of your server.py if you use a src/ layout — container environments dont always resolve Python paths correctly.

Feedback welcome!
