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.

MCP Server: TREMOR - Global Macro, Credit & Markets Data (Tigzig V2)

The Tigzig V2 Unified Data Surface: curated macro, credit-stress, valuation, insurance, India, global, markets and FX indicators across 8 categories. Category-first navigation, callable directly from any MCP client. Same dataset as the TREMOR app.

Open, no auth. Two transports (Streamable HTTP + SSE) and an open HTTP API also available at tigzig.com/apis.

What This Server Does

#

Four MCP Tools

  • list_categories - the 8-category menu (also baked into the server instructions so an agent sees the full map at session start, no tool call needed).
  • list_indicators_in_category - per-category indicator catalog (id, name, frequency, last date); optional compact mode.
  • find_indicator - cross-category fuzzy substring search on indicator id and display name.
  • v2_get_series - time series, one or more indicators, wide format (one row per date, one column per indicator). Date filters optional.

Eight Categories

  • us_macro - FRED + Michigan: monetary, labor, inflation, GDP, sentiment, housing, financial conditions
  • us_credit - delinquency + charge-offs (FRED, FFIEC), NCUA credit unions, NY Fed household debt, FDIC banks
  • us_valuation - Shiller CAPE, Buffett indicator, nominal GDP, US Treasury yields
  • us_insurance - Fed Z.1 invested-asset breakdown for Life and P&C insurers
  • india_macro - RBI WSS, MoSPI (IIP, CPI, WPI, GDP), NSE Nifty 50 PE/PB/DivYield
  • global_macro - OECD Business Confidence (37 countries), European sovereign yields
  • markets - daily prices for 12 symbols (equity indices, US 10Y, DXY, gold, copper, WTI, Brent)
  • currencies - daily FX (USDINR, USDJPY, USDKRW, USDTWD, USDTRY, USDPHP, USDVND)

Limits

  • Max 10 indicators per v2_get_series call
  • TSV output carries a # meta line flagging any unknown or empty IDs
  • 60 req/min per IP

MCP Configuration

#

Recommended - Streamable HTTP

https://api.tigzig.com/v2/mcp/http

Newer MCP spec (2025-03-26). Single endpoint, serverless-friendly. Try this first.

Fallback - SSE

https://api.tigzig.com/v2/mcp/sse

Legacy MCP transport (2024-11-05). Use if your client does not yet speak Streamable HTTP.

Adding to Claude.ai

  1. Open Claude.ai - Settings - Connectors
  2. Add custom connector, paste the Streamable HTTP URL
  3. If it does not connect, swap to the SSE URL
  4. Approve - the agent now has list_categories, list_indicators_in_category, find_indicator and v2_get_series

Same URLs work for Cursor, Continue, and any other MCP client. The MCP server identifies itself as "Tigzig V2 Unified Data Surface".

How It Works

#
  • FastAPI backend, same dataset that powers the TREMOR app charts
  • Indicators stored in DuckDB, refreshed on the schedule of each upstream source (bulk downloads + replica 3x daily)
  • MCP layer exposes four category-first tools over Streamable HTTP and SSE
  • Open HTTP API mirrors the same data at /v2/, /v2/categories, /v2/series for non-MCP clients; bulk downloads at /v2/download/all
  • V1 (/tremor/v1/) remains available for existing integrations; V2 is recommended for new ones
  • Cloudflare in front for rate limiting and WAF

Data Sources

#

Indicators are pulled from primary publishers; the dictionary returns the upstream source and source series ID for each entry.

  • US: FRED, NY Fed, NCUA, FDIC, Shiller
  • India: RBI, MoSPI, NSE
  • EU / Global: ECB, OECD

Sample indicator IDs: us_treasury_30y_yield, us_bank_delinq_cc, shiller_cape, india_credit_deposit_ratio.

Example Agent Prompts

#
  • "Pull the last 5 years of US 30-year Treasury yield and US credit card delinquencies. Are they correlated?"
  • "Show me every macro early-warning indicator that is currently above its 2007 pre-crisis level."
  • "List every Indian indicator you can pull and tell me which sources they come from."
  • "Get Shiller CAPE for the last 145 years and tell me how today compares."
