Documentation Overview
attest-mcp-remote
Listed on the official MCP Registry as
io.github.SPAZIO-GENESI/attest-mcp-remote.
Remote MCP server (Streamable HTTP) for the Spazio Genesi digital-work attestation service. Zero install: add the URL as a connector in your MCP client and start verifying and attesting.
No file ever transits — by design. MCP has no reliable client→server file
channel, and this service doesn't want one: every tool works on the SHA-256
fingerprint of the work. Agents with code execution compute it locally
(sha256sum <file>), so the file never leaves the machine it lives on — not
even through this server. For local-file tooling use the stdio package
@spazio-genesi/attest-mcp;
for humans, the website (in-browser
hashing, full privacy) or the Telegram bot @SGAttestBot.
Status
In production. Live at https://attest-mcp-remote.it-e3f.workers.dev/mcp.
All 8 tools implemented, tested, and validated end-to-end against production,
including a real zero-install run from claude.ai (connector by URL, human
Turnstile approval, certificate PDF issued and archived).
Tools
| Tool | Auth | What it does |
|---|---|---|
service_status | none | Health of worker / archive / signer / Bitcoin anchor |
check_anchor | none | OpenTimestamps proof lookup for a fingerprint |
verify_attestation | none | Verify the server HMAC signature of an attestation |
lookup_certificate | none | Archive lookup + permanent links for a fingerprint |
authorize | starts device flow | User approves once in the browser (anti-bot check) |
complete_authorization | device flow | Claims the 24h session token (kept in session state, never echoed) |
attest_hash | session token or API key header | Bind a fingerprint to a signed server timestamp |
create_certificate_pdf | session-scoped | Generate + archive the certificate PDF, returns permanent links |
Credentials: either the zero-config device flow above, or an
Authorization: Bearer sg_k_… header on the connection (e.g. Claude Code:
claude mcp add --transport http attest <url> --header "Authorization: Bearer sg_k_…").
Self-service keys: https://imgauth.spaziogenesi.org/developer/keys
Develop
test/smoke.mjs drives the Streamable HTTP transport end-to-end (initialize →
tools/list → tools/call) against real, public production data (read-only).
test/smoke-auth.mjs covers the credentialed flow and is a local-only
harness: it needs an isolated imgauth wrangler dev (own --persist-to
state, SIGNER_URL emptied) because the user-approval step is simulated by
writing the local D1 directly — see the header comment in the file.
⚠️ When bumping the version
This server is also advertised through an MCP Server Card published by the web interface, which repeats this server's name, version and endpoint:
That file is not generated from this repository, so a version bump here
silently makes it wrong. When you change version in package.json and
server.json, update serverInfo.version in the card too — same release, same
day. (Publishing a card that misstates the version is the same class of problem
as an openapi.json left behind: a descriptor that lies is worse than none.)
Security
Report vulnerabilities → /sicurezza/
(responsible disclosure policy, safe harbor for good-faith research) — this
repo has no security.txt of its own (Worker with no static assets), but
the policy covers the whole project, including this workers.dev service.
