Oig Corporate Integrity MCP Server

@pipeworx/oig-corporate-integrity

HHS-OIG Corporate Integrity Agreements — does this healthcare company or individual have a Corporate Integrity Agreement (CIA), since when, what obligations does it impose, and what is its current status? A CIA is a different condition from an exclusion (see the leie and ny-omig-exclusions packs): an entity under a CIA is still participating in Medicare/Medicaid, under binding compliance obligations OIG negotiated instead of seeking exclusion.

Part of Pipeworx — an MCP gateway connecting AI agents to 1721+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

• oig_cia_check(name, limit?) — checks an entity against the current HHS-OIG CIA roster. An exact name match is the strongest signal; a normalized-name or token match is returned as a labelled candidate, since CIA entity names are frequently compound (a company plus named co-signers, e.g. "SNAP Diagnostics, LLC and Gil Raviv"). For the best match, fetches the entity's own detail page live to return the effective date, term/duration, settlement amount and the agreement PDF URL — none of that is baked, so it is never stale. Returns found: false with the list's as-of date and total agreement count when no match exists.
• oig_cia_obligations(name?, document_url?) — resolves the entity (same matching as oig_cia_check) or takes a document_url directly, fetches the agreement PDF live from oig.hhs.gov, extracts its text, and reports which of six obligation categories (Board Resolution, Independent Review Organization/IRO reviews, Compliance Officer/Committee, Annual or Implementation reporting, a disclosure program, excluded-persons screening) actually appear in the text, each with a short excerpt. Not every CIA includes every category — a sole-individual CIA typically has no Board Resolution clause — and some older, fully closed agreements have no PDF posted at all, reported as found: false, not an error.
• oig_cia_list(status?, limit?, offset?) — browses the baked CIA list by status (Effective / Suspended / Closed / Refused). Fast (no live fetch), but carries only what the list card shows — call oig_cia_check on a specific entity for effective date, term and the agreement document.

Data sources

• https://oig.hhs.gov/compliance/corporate-integrity-agreements/browse-cias/ — the paginated, filterable CIA roster (339 agreements as captured, 20 per page). No JSON/REST endpoint and no bulk CSV/Excel export exist.
• Each agreement's own detail page (/compliance/corporate-integrity-agreements/browse-cias/<slug>/) — effective date, term, settlement amount, category/tags, and the agreement PDF's URL. Fetched live, per call, never baked.
• The agreement PDF itself (oig.hhs.gov/documents/cias/<id>/<file>.pdf) — text PDFs, extracted with shared/src/pdf-text.ts.

Why only the LIST is baked

Root CLAUDE.md's standing rule for this shape: a baked table never sits in gateway module scope. scripts/bake-index.mjs crawls all 17 pages of the browse list and bakes only the entity name, detail-page path, the status badge/date shown on the list card, location and report type — into src/oig-cia-index-data.ts, registered in workers/gateway/src/pack-baked-indexes.json, uploaded to KV at deploy, and injected as args._bakedIndex (fleet #2754 pattern, same as south-dakota-code / ny-omig-exclusions / usgs-mineral-commodities). A missing or malformed injection throws loudly rather than answering "no CIA found" — see src/index.test.ts.

Per-entity detail (effective date, term, settlement amount, the agreement PDF URL and its text) is deliberately not baked — it is fetched live from that one entity's own detail page and PDF on every oig_cia_check / oig_cia_obligations call. Most callers never ask about most of the 339 rows, so pre-crawling all of them would be wasted work; fetching live also means a newly-closed or newly-suspended agreement is visible immediately instead of waiting for the next bake.

Re-run node mcps/oig-corporate-integrity/scripts/bake-index.mjs periodically to refresh the list and recommit. OIG's own page carries no static freshness banner ("As of today") — data_as_of on every response is simply the bake script's own capture date.

Transport/parse failures throw loud

A non-200 from a detail page or PDF, or a 200 whose content no longer matches the shape this pack parses, is reported as a thrown error naming the upstream status — never silently reshaped into found: false, which for a compliance screening tool would be indistinguishable from "no CIA on file". See src/index.test.ts for the stubbed-fetch contract tests.

Reachability

Verified live 2026-10-07 from both a laptop fetch and a throwaway wrangler dev --remote Worker on the prod Cloudflare account: identical 200 responses and byte lengths from the Cloudflare edge on the browse list, a detail page and an agreement PDF (92,934 / 44,393 / 696,577 bytes respectively). This host has no robots.txt at all (404).

Quick Start

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

{
  "mcpServers": {
    "oig-corporate-integrity": {
      "url": "https://gateway.pipeworx.io/oig-corporate-integrity/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/oig-corporate-integrity/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 1721+ 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/oig_cia_check \
  -H 'Content-Type: application/json' \
  -d '{"name":"Alliance Parent, Inc."}'

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

Standalone (no gateway account)

This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:

{
  "mcpServers": {
    "oig-corporate-integrity": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-oig-corporate-integrity"]
    }
  }
}

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-oig-corporate-integrity

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.

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 Oig Corporate Integrity data" })

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