Security
An MCP server is an API surface like any other, so the same hardening applies. How much depends on what your server actually does.
- Data-only server (reads a curated dataset): small surface - rate limiting and input validation are usually enough.
- Database or SQL server: the full database hardening applies - read-only enforcement, query validation, resource-exhaustion blocks.
- Wraps a backend: add the FastAPI backend checks - CORS, auth, concurrency limits, plus the MCP-specific items.
The Tigzig security checklist covers all of it - React, FastAPI, Postgres, DuckDB, Cloudflare and a dedicated MCP section.
Live apps & tools on the same backends
6
Want to see a backend in action? These live apps, tools and custom GPTs run on the SAME APIs and MCP servers above - the Technical Analysis, Security Performance, Yahoo Finance and Markdown-to-PDF backends power all of them.
Portfolio Analytics Agent
MCP AGENTOSS
An MCP agent (not just a server) for portfolio analytics - it drives QuantStats over a conversation. Open the app, or read the docs to mount it.
Quants Agent / Portfolio Analysis Suite
Web app running the Technical Analysis, Security Performance and Yahoo Finance backends together - QuantStats, SPR and TA reports in one place.
Database AI Suite (DATS-4)
Chat with any database. Ask the agent to convert an analysis to PDF and it calls the Markdown-to-PDF backend.
Markdown to PDF (web tool)
The web front end for the Markdown-to-PDF backend - paste markdown, download a PDF.
Custom GPTs
Several ChatGPT custom GPTs are wired to these same backends - Multi-Database, Quants, and Technical Analysis.
Flowise / n8n agent flows
Low-code agent flows that mount these MCP servers to produce reports and PDFs.
