Overview

AI-generated overview

A local stdio MCP server exposing StillOS notary tools: signed claim commitments, claim verdicts, OFAC sanctions screening and corporate distress scoring, each

What you can do
Commit a claim string to a tamper-evident, Ed25519-signed receipt for a fee in USDC on Base. Request a signed verdict on a claim resolved against a named external ground-truth source. Screen an entity name against the OFAC SDN sanctions list and get a signed receipt with a freshness timestamp. Get a corporate distress-foresight score derived from live SEC XBRL data. Each call is a real HTTP POST to the provider's notary endpoints, and unpaid calls return an x402 payment challenge to parse, pay and retry.
When to use it
When you need a signed, independently verifiable record of a claim, a verdict checked against a cited source, a sanctions name screen, or a corporate distress score, and you are willing to pay per call in USDC on Base.
Requirements
Runs locally via npx (Node.js) over stdio. No declared authentication, environment variables or headers. Network access to the provider's notary endpoints is required. A crypto wallet able to pay USDC on Base is needed, since each tool call is paid through the x402 flow.
Before you install
Every tool call costs real money in USDC on Base (prices range from about $0.001 to $0.15 per call), and the assistant must handle the x402 payment challenge and pass a payment header value. The package is marked deprecated in favor of a successor package. Requests, including claim strings and entity names, are sent to the provider's servers. Verdicts are signed but rely on the provider's cited sources and a small on-chain bond.

Installation

In SourceWeft

  1. Open Stillos Notary in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

stillos-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Deprecated — superseded by stillos-notary-mcp (npm).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.

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
