StatCite

Economic statistics your AI can actually cite.

StatCite is a free remote MCP server + REST API serving official economic statistics — World Bank, IMF WEO, ECB reference rates, optional FRED — where every number ships with its full citation: source, dataset, series ID, canonical URL, license, retrieval date, and a ready-to-paste citation sentence. Plus verify_stat: check any claimed economic figure against the official series and get a verdict (match / close / mismatch / cannot_verify) with diagnostics for the classic errors (wrong year, percent-vs-decimal, millions-vs-billions).

• Website & docs: https://statcite.com · docs · OpenAPI · llms.txt
• MCP endpoint: https://statcite.com/mcp (Streamable HTTP, stateless, no auth)

Data & licensing

StatCite does not originate the underlying statistical observations; derived values and verification verdicts are calculated transparently from cited source data with the method disclosed. World Bank (CC BY 4.0); IMF (per IMF terms — attribution + downstream conditions; commercial reuse may require IMF permission); ECB (attribution, informational rates); Eurostat via DBnomics (CC BY 4.0); FRED disabled by default (an operator enabling it must review the current FRED API Terms of Use first — they include restrictions relevant to caching, redistribution, and AI/software use). IMF WEO projections are labeled as projections; WEO is served via DBnomics, which can lag the IMF's release calendar — responses cite the resolved vintage and flag stale ones. Server code: MIT.
