# pipeworx `congress` — Congress

## Coverage
US congressional bills, members, and votes via GovTrack — no API key required

Catalog `tool_count`: 5. Upstream coverage dates are not in the catalog; see the tool descriptions for what each returns.

## Access
MCP endpoint `https://gateway.pipeworx.io/congress/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 41 tools: these 5 plus the 36 platform tools every pack endpoint lists.

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

- `search_bills` — ANSWERS "what bills about X has Congress introduced" / "recent congressional bills on X" / "federal legislation about X" / "find the <Named> Act" — searches US FEDERAL congressional bills (US House & Senate, national la… Required: `query`.
- `get_bill` — Look up one congressional bill from GovTrack by its real-world identifier — congress number, bill type and bill number, e.g. the 118th Congress H.R. 1. Required: `congress`, `bill_type`, `number`.
- `get_members` — Get current members of Congress with their name, party, state, district (for representatives), and contact information. No required arguments.
- `get_votes` — Get recent congressional votes on bills, newest first. No required arguments.
- `get_recent_bills` — List the most recent congressional bills — newest first by introduction date or by latest action. No required arguments.

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

## Auth
Catalog `auth.shape`: `keyless`. Verbatim detail: "No key required — open upstream, callable as-is." 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 listed, not called). Upstream limits are not stated in the catalog.

## Freshness
Not stated in the catalog. Reliability: not measured — catalog says treat as unknown, not good.

## Known gaps
- Cost per call as quoted: 50 credits ($0.0050), category `gov`, basis `list`.
- No catalog notes on cost or licence.
- 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.
