Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

screen

screen_exclusion

Screens one person or business name against a mirrored copy of the HHS-OIG List of Excluded Individuals/Entities (LEIE), the list of people and businesses excluded from Medicare, Medicaid and other federal health care programs. Person names match in any word order, with or without middle names or initials, suffixes (Jr, Sr, III), credentials (MD, RN), punctuation, hyphenated surnames, common nicknames and one-letter typos; business names match without company-form words (LLC, Inc, PC) and with abbreviations and small typos. Returns ranked possible matches with score, name, general category and specialty, city, state, ZIP, NPI when present, exclusion type with its meaning, exclusion date and any waiver, or a no-match result at the threshold, plus the list's as-of date. Optional state, NPI and date-of-birth filters narrow common names.

screen_exclusions

Screens up to 25 person or business names in one call against the same LEIE mirror as screen_exclusion and returns only the best possible match per name (or no match at the threshold) in compact form, with a summary count. When a state, npi or dob filter leaves out every record at or above the threshold, the result for that entry is no_match_after_filters and it shows the best record the filter left out. Each entry can be a name string or an object with name and optional state, npi and dob (YYYY-MM-DD).

exclusion

exclusion_list_status

Returns the version of the mirrored LEIE: OIG's last update date and the month the data runs through, the source file's timestamp, size and hash, record counts (individuals, entities, with NPI), the latest monthly supplement, and when the mirror was last built and last checked for updates.

npi

check_npi

Validates a 10-digit National Provider Identifier (check digit) and looks it up in the NPI field of the LEIE mirror. Returns the excluded record(s) that carry it, or a not-on-list result. Most LEIE records have no NPI, so a not-on-list result does not show that a provider is not excluded.

Healthcare Exclusion Lookup — questions

Answers built from our own checks of this server.

What can Healthcare Exclusion Lookup do?

It exposes 4 tools, read directly from the server on our last check. Among them: check_npi, exclusion_list_status, screen_exclusion, screen_exclusions. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Healthcare Exclusion Lookup working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 80 of 80 checks got a reply (100.0%), average response time 152 ms. The bar chart above shows every period we have measured.

How do I connect Healthcare Exclusion Lookup?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Healthcare Exclusion Lookup need an API key?

No. Healthcare Exclusion Lookup completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Healthcare Exclusion Lookup?

It answers our handshake in 152 ms on average, which is faster than 82% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
