Best used with an AI agent

40+ live apps, open data APIs, MCP servers, and 200+ guides - more than anyone wants to click through. Point your AI here and it reads the whole map and does the work: finds the tool, pulls the data, runs the analysis, and hands you the links.

Here for the open-source code? Your agent finds the right repo for you - and can even clone and deploy it.

Prefer to explore on your own? Go right ahead.

Paste this to Claude Code, Codex, or any AI agent:
Go to tigzig.com and read tigzig.com/llms.txt. It is a practitioner toolkit - 40+ analytics apps, open no-auth data APIs, MCP servers, open-source repos (github.com/amararun), and 200+ build guides. Help me [your task]. Surface the exact links; where there is an API or MCP, call it directly; and if I want to self-host, find the repo and help me deploy it.

Claude for Analytics - in Excel, PowerPoint and Cowork

Everything I have built and written on using Claude (Anthropic's AI) inside Excel and PowerPoint - and as a universal agent for day-to-day analyst work. One-shot models, 50-chart dashboards, pulling live database and quant data into a sheet over MCP, plus the setup guides and playbooks. By a practitioner. Free and open.

Claude in Excel: build models, dashboards and reports

What Claude actually does once it is inside a spreadsheet - real, one-shot builds from a practitioner's sheet, not demos.

The working guides: Excel, PowerPoint, what works

The how-to playbooks - Excel and PowerPoint tips, an honest "is it worth it", and how Claude in Excel stacks up against Python-in-Excel.

Pull live data into Excel: databases and quant metrics over MCP

Connect Claude in Excel to your databases and analytics backends over MCP, so numbers come straight into the sheet - no copy-paste, no export dance. Start with the setup guide.

Beyond Excel: Claude as a universal agent

Excel is one front end. The same Claude drives PowerPoint, files, databases, coding and analysis from one place - Cowork and Claude Code. Lighter reading, and the research behind why it works.

More: the MCP hub, APIs, security and the apps

The infrastructure behind all of this - the MCP servers and APIs Claude connects to, the apps built with Claude Code, and what Claude looks like on the security side.
