Committee Releases MCP Server

@pipeworx/committee-releases

Documents congressional committees publish on their own websites — press releases, oversight letters, staff reports, released interview transcripts and investigation files. Keyless.

Part of Pipeworx — an MCP gateway connecting AI agents to 1863+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

• search_committee_documents(...) — find documents by headline across seven committees, filtered by committee, doc_type and (where dates exist) since.
• get_committee_document(...) — a document page's headline, publication date, published text and attached PDFs with URLs and sizes.
• list_committee_document_types(...) — which committees are covered and what each publishes.

Auth

None.

Why this exists

congressional-documents covers GovInfo — the official printed record, which lags the event by months and never receives the ad-hoc material a committee posts to its own site. This covers that gap, within hours of publication.

Committees covered

~40,600 documents indexed. All 30 major House and Senate committees were surveyed on 2026-07-30: most House committees publish no sitemap at all, so they cannot be added without a new adapter.

flat committees publish a sitemap with no dates. Their results carry last_updated: null, sort alphabetically rather than by recency, and refuse since instead of applying it to undated rows — which would return pre-cutoff documents as though they had passed the filter. The response says so via dates_unavailable.

Not every committee publishes every type. A doc_type a committee does not publish returns an explicit unavailable_types and a note, never an empty list that would read as "nothing on the subject".

Coverage and limits

• Search matches the document headline/slug, not body or PDF text. Searching 40,000 pages of body text needs full-text indexing. A null result means no headline matched — not that the subject is absent.
• PDF text is not extracted. Attachments come back as url + filename + bytes. Quote the page text and cite the attachment as a link; do not represent a PDF as having been read.
• Some pages are pure file wrappers with no prose of their own; those return empty text plus a no_prose_note rather than the site footer.
• get_committee_document fetches a caller-supplied URL, so it is host-allowlisted to the seven committee domains.

A deliberate omission

No person→mentions tool, for the reasons set out in congressional-documents: a name is not an identifier, and being named in a committee document is not an allegation.

Data sources

Each committee's Yoast sitemap index or sitemap.xml, e.g.:

• https://oversight.house.gov/sitemap_index.xml
• https://www.hsgac.senate.gov/sitemap_index.xml
• https://www.judiciary.senate.gov/sitemap.xml

All are served under a robots.txt with an empty Disallow: — crawling explicitly permitted.

Quick Start

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

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

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/committee-releases/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:

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

Both URLs reach the same gateway and the same 1863+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

curl -X POST https://gateway.pipeworx.io/v1/tools/search_committee_documents \
  -H 'Content-Type: application/json' \
  -d '{"query":"subpoena","limit":5}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/search_committee_documents. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Run it from npm

@pipeworx/mcp-committee-releases is a local stdio bridge to the Pipeworx gateway: your MCP client starts it with npx, and it forwards every call to the same https://gateway.pipeworx.io/committee-releases/mcp endpoint shown above. It needs network access; there is no offline mode.

{
  "mcpServers": {
    "committee-releases": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-committee-releases"]
    }
  }
}

Without a key it calls anonymously, capped at 50 calls a day. A free account raises that to 200 a day: get a key at https://pipeworx.io/signup and add "env": { "PIPEWORX_API_KEY": "<your key>" } to the server entry. The key is sent as a Bearer token, the same way a hosted connection sends it, so calls are metered and billed exactly as they are there.

It lists only this pack's tools by default. Set PIPEWORX_META_TOOLS=1 to also list ask_pipeworx and the other gateway-wide tools.

Behind an HTTPS proxy: Node's built-in fetch does not read HTTPS_PROXY by default. Newer Node releases honour it when NODE_USE_ENV_PROXY=1 is set; check your Node version's documentation.

Using with ask_pipeworx

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:

ask_pipeworx({ question: "your question about Committee Releases data" })

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