Tigzig Tremor v2 Is Live. 330+ Macro + Credit Indicators Behind an MCP. 83% Lighter Startup. Just Ask Your AI Agent.

Published: June 24, 2026

Pulling macro and credit data for an analysis is mostly grunt work. Finding the series, downloading, cleaning. I put it all behind an MCP. Now you just ask Claude Cowork, Claude in Excel, whichever AI agent you use. In plain English. 330+ indicators across US, India, global macro, credit, markets and FX .. all at one place ...

Now ask your AI agent:

v2 is now live. Earlier the whole catalog was stuffed into one giant description the agent had to load up front, about 8,000 tokens before it did anything. Now knowledge discovery has a separate path ... it charts its own path.. sees an 8-category menu, drills into just the tables it needs, pulls only the relevant bits. That cut the startup load by about 83%.

And that discovery layer carries my own notes on each series. Like "this charge-off is quarterly, multiply by 4 to annualize". So the AI does not quietly get it wrong.

Free. Open. No sign-up. Use the live MCP or install your own. Or just have your AI hit the APIs directly.
