# pipeworx `fred` — FRED

## Coverage
US economic series from the St. Louis Fed — interest rates, inflation, unemployment, GDP — with the release each figure came from.

Catalog `tool_count`: 6. Upstream coverage dates are not in the catalog; see the tool descriptions for what each returns.

## Access
MCP endpoint `https://gateway.pipeworx.io/fred/mcp` — JSON-RPC `tools/list` and `tools/call` over POST, SSE-framed response (`event: message`, one `data:` line; the answer is in `result.structuredContent`). `tools/list` on 2026-10-01 returned 42 tools: these 6 plus the 36 platform tools every pack endpoint lists.

Tools (names and first sentence of each description as served on 2026-10-01):

- `fred_get_series` — AUTHORITATIVE historical time-series for US economic indicators from FRED (Federal Reserve Bank of St. Louis — the official US macroeconomic data repository, 800k+ series). Required: `series_id`, `_apiKey`.
- `fred_search` — Search for economic data series by keyword. Required: `search_text`, `_apiKey`.
- `fred_series_info` — Get metadata for a series: title, units, frequency, seasonal adjustment, notes, and date range. Required: `series_id`, `_apiKey`.
- `fred_category` — Browse economic data by category (housing, employment, money/banking, etc.). Required: `_apiKey`.
- `fred_releases` — Check upcoming and recent economic data releases. Required: `_apiKey`.
- `fred_release_dates` — Economic data RELEASE CALENDAR from FRED — the dates indicators are/were published, including FUTURE scheduled dates. Required: `_apiKey`.

Client setup: `claude mcp add pipeworx-fred -- npx -y mcp-remote https://gateway.pipeworx.io/fred/mcp`.

Called on 2026-10-01 without a credential: `fred_series_info {series_id: UNRATE}` → HTTP 200, title "Unemployment Rate", observation_end 2026-08-01, last_updated 2026-09-04. The schema lists `_apiKey` as required; the call succeeded without it.

## Auth
Catalog `auth.shape`: `platform-keyed`. Verbatim detail: "Pipeworx supplies the fred API key — no key needed from you. You may override it with `_apiKey`." No credential is needed at the gateway to list or call (anonymous tier; see the gateway record).

## Rate limits
Gateway anonymous tier: 50 calls per day per IP, reset 00:00 UTC, printed in `x-ratelimit-*` headers (observed 2026-10-01 on the fred and weather packs; this pack was called). Upstream limits are not stated in the catalog.

## Freshness
Not stated in the catalog. Reliability: measured 100% over 14 synthetic checks in 7d (last checked 2026-09-28).

## Known gaps
- Cost per call as quoted: 0 credits ($0.0000), category `gov`, basis `list`.
- Cost note, verbatim from the catalog: "The fred upstream licence forbids charging any incremental fee for this data. It is free on every tier and does not count toward volume pricing."
- Licence flag in the catalog: `non-commercial`.
- Your own upstream key can be passed as `_apiKey`.
- This record is the catalog's description plus one `tools/list`; it is not a test of the upstream data. Reuse it to find the tool, then observe the upstream yourself.

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
