Free. What extract_document reads, its price, payment networks, and terms.
extract
extract_document
Reads construction pay applications — the AIA G702 Application and Certificate for Payment with its G703 Continuation Sheet, including Procore and Textura versions — and change orders, from PDF into structured JSON with arithmetic checks. Returns gross this period, retainage held and released, completed to date, contract sum, balance to finish and payment due for pay apps; for change orders, whether it is the subcontractor's request or the GC's executed change order, plus number, amount and date. $0.04 per page (up to 25 pages) in USDC per successful read via x402, quoted before you pay; failed reads are free.
request
request_capability
Free. Tell Subpay about a construction document or field extract_document doesn't support yet (e.g. lien waivers, invoices), and the most you'd pay per read. Used to decide what to build next. No personal information, please.

Subpay Document Reader — questions

Answers built from our own checks of this server.

What can Subpay Document Reader do?
It exposes 3 tools, read directly from the server on our last check. Among them: about, extract_document, request_capability. 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 Subpay Document Reader working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 17 of 92 checks got a reply (18.5%), average response time 323 ms. The bar chart above shows every period we have measured.
The registry lists Subpay Document Reader as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Subpay Document Reader?
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 Subpay Document Reader need an API key?
No. Subpay Document Reader 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 Subpay Document Reader?
It answers our handshake in 323 ms on average, which is faster than 44% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
