@pipeworx/congressional-documents

Full-text search and retrieval over the official record of Congress — hearing transcripts, committee reports and the Congressional Record. Platform key (data.gov), BYO accepted.

Part of Pipeworx — an MCP gateway connecting AI agents to 1394+ live data sources.

Tools

• search_congressional_documents(...) — search the full text of hearings, committee reports, committee prints, House/Senate documents and the Congressional Record. doc_type takes plain words ("hearings", "reports", "record").
• get_congressional_document_text(...) — the actual document text, with its page citation and govinfo.gov URL, paged via offset/next_offset (a hearing runs ~200k characters).
• list_congressional_document_types(...) — what each document type contains, and what this source covers. Keyless.

Auth

Platform key (PLATFORM_DATAGOV_KEY), or BYO via _apiKey. Free, instant signup at https://api.data.gov/signup — one key works across GovInfo and most federal APIs.

Why this exists

All of this is reachable through the govinfo pack, but only as search_packages({collections:"CHRG"}) and list_granules. No model asked "what was said in the congressional hearing about X" will reach for a granule API or know that CHRG means hearings. The data was never missing; the path to it was.

It exists for grounding: this corpus is voluminous, badly structured and heavily paraphrased second-hand, which makes it exactly what models confabulate about. Every result carries the package/granule id, the official citation and a govinfo.gov URL so an answer can quote rather than recall.

Coverage

Published documents only. A hearing transcript appears months after the hearing. Ad-hoc releases a committee posts to its own website never reach GovInfo at all — use search_committee_documents (committee-releases) for those.

page_citation is a Congressional Record convention ([Pages S6557-S6559]); hearings do not carry one, so it is legitimately null there.

A deliberate omission

There is no person-centric tool — nothing that takes a name and returns documents mentioning them. Two reasons:

1. A name is not an identifier. Searching "Epstein" across hearings ranks Anthony C. Epstein, a D.C. Superior Court nominee, first. A person-shaped tool would silently merge unrelated people who share a surname.
2. Appearing in a document is not an allegation. The record names witnesses, staff, cited authors and people mentioned once in passing. A "is X in the record" tool invites a summarizer to collapse was mentioned into was implicated.

Every response carries that disclosure. Please do not add a person→mentions tool; the omission is the design.

Data sources

• https://api.govinfo.gov/search
• https://api.govinfo.gov/packages/{packageId}/granules/{granuleId}/htm

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "congressional-documents": {
      "url": "https://gateway.pipeworx.io/congressional-documents/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 1394+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Congressional Documents data" })

The gateway picks the right tool and fills the arguments automatically.
