Details
From the project READMEstillos-notary
Deprecated — superseded by stillos-notary-mcp (npm).
This package still works (the underlying notary API doesn't change), but stillos-notary-mcp is the actively developed
package: more tools (verify_receipt, file_dispute as first-class), a live remote HTTP MCP endpoint in addition to
stdio, and the current canonical domain. Install that one for new integrations.
This repo stays up as the historical home of the public Vauban/ForeSeal interop discussion (issue #1).
Direct tool access to StillOS's signed, x402-paid verification and screening primitives — no separate API docs lookup, no SDK install beyond this package.

Tools
- notary_commit — commit any claim string to a tamper-evident, Ed25519-signed receipt. $0.10 USDC on Base.
- notary_claim_verdict — signed verdict on a claim, resolved against a named external ground-truth source. Launch price $0.05 USDC on Base through 2026-10-13.
- notary_screen_entity — OFAC SDN sanctions name screen, signed receipt, freshness timestamp. $0.001 USDC on Base.
- notary_distress_score — validated corporate distress-foresight score (Altman Z-score from live SEC XBRL). Backtested 71% sensitivity / 100% specificity / ~109-day median lead on real Chapter 11 filings. $0.15 USDC on Base.
Payment
Every tool call is a real HTTP POST to https://stillosdigitalholdings.com/notary/*. An unpaid call returns the endpoint's real x402 402 response verbatim — parse the accepts[] array, pay, and retry the same tool call with an x_payment_header argument containing your X-PAYMENT header value.
Every paid response is Ed25519-signed and independently verifiable at GET /notary/verify?hash=... — you don't have to trust StillOS's word for it.
Backed by a $10 on-chain correctness bond: any counterparty can dispute a signed verdict and get paid up to $1 if it's proven wrong against its own cited source. See /notary/dispute.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
