Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
FRED economic time series + ALFRED vintages: data as originally published, before revisions.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

**FRED® economic data inside your AI agent — including what the numbers said *before* the revisions. An MCP server for the Federal Reserve Bank of St. Louis's FRED® API: search and read 800,000+ U.S. and international time series, follow the release calendar, and — the distinctive part — query ALFRED® vintage data**: any series exactly as it was known on a past date, and any single data point's full revision history from its initial print to today's value.
Read-only, built on public endpoints, powered by your own free FRED API key. Live API calls with a volatility-aware cache (vintage reads are immutable and cache long; current data stays fresh) — no bulk mirroring.
This product uses the FRED® API but is not endorsed or certified by the
Federal Reserve Bank of St. Louis. By using this server you agree to the
Status: v0.1.0 — live on PyPI (uvx mcpwright-fred) and the official MCP Registry (io.github.mcpwright/fred-mcp). 9 tools, CI-gated, built on mcpwright-core.
Economic numbers get revised — sometimes dramatically. The *advance* estimate of Q4-2008 real GDP told policymakers the economy was shrinking far more slowly than the number that stands today. If an agent reasons about what decision-makers knew *at the time* using *current* data, it is quietly wrong. get_series_as_of and get_revision_history make as-published data a first-class question.
| Tool | What it does |
|---|---|
search_series | Find series IDs by free text, best matches first |
get_series | One series' full metadata + verbatim notes |
get_observations | A date window of values; transforms (pct_change_yoy, …) + downsampling |
get_latest | The most recent value + the next scheduled release date |
compare_series | 2–5 series aligned on one date axis |
get_release_calendar | Upcoming data releases ("when's the next jobs report?") |
get_series_as_of ⭐ | A series exactly as known on a past date (ALFRED vintage) |
get_revision_history ⭐ | One data point's life: initial print → every revision → today |
get_vintage_dates ⭐ | When a series was released/revised; bounds the vintage tools |
All tools are read-only and annotated as such.
Every question below was run live against the real FRED API through these tools (answers as of June 2026 — ask again and they'll be current).
Everyday questions:
get_latest(UNRATE) → 4.3% (May 2026), next release 2026-07-02.get_latest(DGS10) → 4.53% (it correctly skips the . rows daily series publish on holidays).get_observations(CPIAUCSL, transform=pct_change_yoy) → 2.4% → 3.3% → 3.8% → 4.2% over Feb–May 2026.search_series → MEHOINUSA672N (real) and MEHOINUSA646N (nominal), annual.compare_series([UNRATE, JTSJOL]) → one aligned table.get_release_calendar(7) → 241 release dates, CPI included.get_observations(A191RL1Q225SBEA) → −0.6, +3.8, +4.4, +0.5%.get_observations(CPIAUCSL, frequency=annual) → one row per year.Questions only the vintage tools can answer:
get_series_as_of(GDPC1, "2009-02-15") → a −3.8% annualized decline as known then (in chained-2000 dollars — the metadata is vintage-pinned too) versus −8.5% in today's data. Policy ran on the first number.get_revision_history(UNRATE, "2020-05-01") → first published as 13.3 (2020-06-05), currently 13.2, with each revision dated.get_series_as_of(MORTGAGE30US, "2022-03-16") → 3.85% as known then; 6.48% today.get_vintage_dates(GDPC1) → 415 vintages since 1991-12-04.You need a free FRED API key (takes seconds): https://fred.stlouisfed.org/docs/api/api_key_request.html.
