Cf Exclusion Check missed 3 checks this week

Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.

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

exclusion

exclusion_batch_check

Screen 2-200 people/businesses against the same sources as exclusion_check in one call. Tiered price by item count: $0.30 (2-10), $1.00 (11-50), $3.00 (51-200), charged once via x402. An invalid item is reported in place, not a failure; all-invalid is refused before charging.

exclusion_check

Screen a person or business against the HHS-OIG List of Excluded Individuals and Entities (LEIE) AND the SAM.gov exclusions list. Costs $0.05 per call via x402. Returns a verdict, a confidence level, the basis of each match, and the reason it matched. A match is a name match unless it was made on an identifier (npi, uei, cage); it is not an identity determination.

exclusion_sources

List the loaded exclusion sources (OIG LEIE and SAM.gov), their row counts, load dates, load completeness and whether a bulk reseed is due. Free. Screening itself is paid: exclusion_check per name, or exclusion_batch_check for 2-200 at once ($0.30/$1.00/$3.00 by size).

Cf Exclusion Check — questions

Answers built from our own checks of this server.

What can Cf Exclusion Check do?

It exposes 3 tools, read directly from the server on our last check. Among them: exclusion_batch_check, exclusion_check, exclusion_sources. 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 Cf Exclusion Check working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 565 ms. The bar chart above shows every period we have measured.

How do I connect Cf Exclusion Check?

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 Cf Exclusion Check need an API key?

No. Cf Exclusion Check completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Cf Exclusion Check?

It answers our handshake in 565 ms on average, which is faster than 20% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
