Mi Medical Exclusions

@pipeworx/mi-medical-exclusions

Michigan Medicaid provider sanctions screening. Check a provider by name, NPI or license number against the Michigan Department of Health and Human Services (MDHHS) List of Sanctioned Providers, the state-level counterpart to the federal HHS OIG LEIE (leie pack) and sibling of il-medical-exclusions, tx-medical-exclusions, ny-omig-exclusions, ca-medical-exclusions and fl-medical-exclusions.

Part of Pipeworx — an MCP gateway connecting AI agents to 1866+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

• mi_medical_check_exclusion(name?, npi?, license?, limit?): screens a provider. An NPI or license match is an identification; a name match, even an exact one, is a candidate lead only (no date of birth is published). The response leads with counts by sanction source, then the matches. Each match carries the sanction date and source, a second sanction date and source where present (often the action being lifted), provider category and MDHHS's reason text. A no-match names the filters tried.
• mi_medical_exclusion_coverage(year? | start_date? end_date?): totals by sanction source, individuals vs businesses, NPI, license and reason coverage, oldest and newest sanction date and the list's own publication date. With year or a date range it counts sanctions in that window over the whole list, split by sanction source. The counted field is sanction_date (the first Sanction Date column), never the second date; the response says so.

Auth

Keyless.

Data source

Michigan Department of Health and Human Services, List of Sanctioned Providers (4,111 rows at capture). It merges sanctions from MDHHS, its Office of Inspector General, Licensing and Regulatory Affairs, the former DCH and HHS; each row names its source. data_as_of is the publication date printed on the list itself.

What the list does and does not say

• MDHHS says the list is built partly from outside sources and may be incomplete.
• The reason field is free text and is blank on about 60% of rows; some values are Social Security Act section numbers such as 1128(a)(1), not plain language.
• No date of birth and no reinstatement flag. When an action was lifted the row usually stays with a second date (for example "Summary Suspension Terminated"), so read reason and second_sanction_date together before calling anyone currently sanctioned.

Personal data

The list has a City column. It is kept for businesses only; for any individual it is dropped at ingest, and a test asserts it. No street address or date of birth is published or served. This follows the standing rule for state exclusion packs: name plus the sanction record plus the date, never an address for an individual.

How the data is served

The publication is a bulk spreadsheet, not a query service. It is copied by scripts/bake-index.mjs, registered in workers/gateway/src/pack-baked-indexes.json, uploaded to KV at deploy and injected as args._bakedIndex (never a module-scope import; fleet #2754). A missing or malformed injection throws loudly rather than answering "not found".

Refresh: re-run node mcps/mi-medical-exclusions/scripts/bake-index.mjs and commit; there is no scheduled refresh yet, same as the sibling baked packs.

Quick Start

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

{
  "mcpServers": {
    "mi-medical-exclusions": {
      "url": "https://gateway.pipeworx.io/mi-medical-exclusions/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/mi-medical-exclusions/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 1866+ 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/mi_medical_check_exclusion \
  -H 'Content-Type: application/json' \
  -d '{"name":"1st Priority Physical Therapy"}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/mi_medical_check_exclusion. 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": {
    "mi-medical-exclusions": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-mi-medical-exclusions"]
    }
  }
}

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-mi-medical-exclusions

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 Mi Medical Exclusions data" })

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