Today is the operative word: we check Subproof every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 5

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

compliance

get_compliance_summary

Get the subcontractor compliance summary: totals for tracked, not received, lapsed cover, lapsing this week, and awaiting check.

expiring

get_expiring_cover

List subcontractor documents expiring within the next N days (default 30) so certificates can be renewed before a sub goes uncovered.

export

export_compliance_report

Export the full subcontractor compliance report as CSV text (sub, document, due date, status, request history).

sub

search_sub_docs

Search subcontractor documents by sub name or document type. Returns matching records with expiry date and status (on file, needs check, not received, lapsed).

uninsured

list_uninsured_subs

List subcontractors with lapsed or missing insurance documents — the ones creating liability exposure right now. Most dangerous first.

Subproof — questions

Answers built from our own checks of this server.

What can Subproof do?

It exposes 5 tools, read directly from the server on our last check. Among them: export_compliance_report, get_compliance_summary, get_expiring_cover, list_uninsured_subs, search_sub_docs. 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 Subproof 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 209 ms. The bar chart above shows every period we have measured.

How do I connect Subproof?

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

Does Subproof need an API key?

No. Subproof completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Subproof?

It answers our handshake in 209 ms on average, which is faster than 60% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
