The Unified Agenda of Federal Regulatory and Deregulatory Actions — every RIN
(Regulation Identifier Number) a federal agency has told OIRA it intends to
propose, finalize, or has completed, published biannually since Fall 1995.
This is the LEADING record ahead of ecfr/federal-register's trailing one:
an agency's "planning to propose X" shows up here, edition by edition, often
years before the same rule actually publishes or takes effect.
Part of Pipeworx — an MCP gateway connecting AI agents to 1683+ live data sources.
reg_agenda_search(agency?, keyword?, stage?, edition?, limit?) — search RINs by agency, free-text keyword, and/or rulemaking stage. Defaults to the newest edition on file.reg_rin(rin) — full detail for one RIN across EVERY edition it has appeared in, showing how its stage/status changed over time.reg_agency_agenda(agency, edition?, limit?) — one agency's full regulatory agenda for an edition, grouped by rule_stage.reg_agenda_coverage() — which editions are currently loaded (oldest/newest, total rows).Keyless — no operator key needed. Backed by reginfo_rins, refreshed
monthly by workers/data-pipeline (dataset reginfo).

Editions run REGINFO_RIN_DATA_199510.xml .. present, April(04)/October(10)
each year.A missing edition answers HTTP 200, not 404. reginfo.gov serves a ~50KB
HTML "no such report" page (Content-Type: text/html) for an edition that
was never published — a real edition answers Content-Type: application/xml.
The ingest HEAD-probes content-type before ever GETting a file, so a not-yet-
published edition (or a genuine off-cycle gap in the pre-2000 grid) costs a
cheap HEAD request rather than leaking an HTML page into the data.
One row PER (rin, publication_id), not per RIN. A RIN's rule_stage
changes edition to edition ("Proposed Rule Stage" → "Final Rule Stage" →
"Completed Actions") — that history is the whole point of this dataset, so a
newer edition never overwrites an older one. reg_rin returns every edition
a RIN has appeared in, newest first.
Coverage grows in gradually, not all at once. The backfill drains in
edition by edition rather than loading all ~60 editions back to 1995 in one
pass; reg_agenda_coverage reports exactly which editions are loaded right
now, so a caller can tell "not backfilled yet" apart from "genuinely never
published".
Agency matching covers name, acronym, AND code, and matches on either the direct agency or its PARENT — asking for "Interior" also surfaces its sub-agencies' (e.g. Fish & Wildlife) rules, since the source records both levels per RIN.
The abstract is HTML wrapped in CDATA in the source XML. The ingest
strips tags and decodes entities before writing the abstract column, so
callers only ever see plain text.
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
tools/list at https://gateway.pipeworx.io/reginfo/mcp returns the tools in the table
above plus the shared Pipeworx meta-tools — ask_pipeworx,
discover_tools, search_within, remember/recall and the rest of the
gateway-wide set. So the tool count you see is larger than this table: a
single-pack endpoint currently lists roughly 30 shared tools alongside the
pack's own. The connection's initialize response states its exact scope, and
is the authoritative answer for a given day.
This is deliberate, not multiplexing by accident. The meta-tools are what let a
scoped connection answer a question this pack does not cover — via
ask_pipeworx, which routes across the whole catalog — without you adding a
second MCP server. There is currently no way to mount a pack endpoint without
them; if the extra schemas cost you more context than the routing is worth,
connect to the full gateway once rather than to several pack endpoints.
Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:
Both URLs reach the same gateway and the same 1683+ data sources. The
only difference is which pack's tools are listed directly; ask_pipeworx
reaches all of them from either one.
No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/reg_agenda_search. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.
This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:
Or run it directly to confirm it starts:
It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call
for only this pack's tools — none of the shared meta-tools the gateway
connection above adds. Same source, same tools, no ask_pipeworx routing.
Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:
The gateway picks the right tool and fills the arguments automatically.
