Connect io.github.SPAZIO-GENESI/attest-mcp-remote and your agent gets 8 tools, among them attest_hash, authorize, check_anchor. It answers at https://attest-mcp-remote.it-e3f.workers.dev/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 11 September 2026; the last check, on 20 October 2026, succeeded.
Zero-install remote MCP server for proof-of-existence file attestation.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
attest_hash | Attest a work: the service binds the SHA-256 fingerprint to a server-side timestamp and signs it (HMAC). Requires a credential (device flow via `authorize`, or an API key header). Optional declared metadata (title/author/year/notes) are nor Inputs: sha256, name, size, type, titolo, autore |
authorize | Start the device-flow authorization to attest works in this session (up to 20 attestations, 24h). Returns a link the USER must open in a browser and approve (anti-bot check included). After the user approves, call `complete_authorization`. |
check_anchor | Check whether a work's SHA-256 fingerprint has an OpenTimestamps proof anchored in Bitcoin. The proof is created at attestation time and matures (pending → Bitcoin-confirmed) within a few hours. Inputs: sha256 |
complete_authorization | Complete the device-flow authorization after the user approved in the browser. Polls the service briefly; if approval hasn't happened yet, just call this tool again. |
create_certificate_pdf | Generate and archive the certificate PDF for a fingerprint attested in this session with `attest_hash`. The PDF is cryptographically signed, anchored in Bitcoin (OpenTimestamps) and archived server-side; this tool returns the permanent link Inputs: sha256 |
lookup_certificate | Look up whether a work's SHA-256 fingerprint has an attestation certificate in the public archive, and get its permanent links (public certificate page, PDF download, OpenTimestamps proof, browser verification). Trust model: this informatio Inputs: sha256 |
service_status | Health of the Spazio Genesi attestation service components: worker (attestation engine), archive (certificate storage), signer (PDF cryptographic signature), anchor (Bitcoin/OpenTimestamps calendars). Values: ok | degraded | down | n/d. |
verify_attestation | Verify the server HMAC signature of an attestation issued by the Spazio Genesi service. Confirms that the attestation string (fingerprint + timestamp) and any declared metadata are authentic and untampered. Note: this checks the SIGNATURE o Inputs: sha256, attestazione, hmac, titolo, autore, anno |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://attest-mcp-remote.it-e3f.workers.dev/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: io.github.spazio-genesi. Endpoint host: attest-mcp-remote.it-e3f.workers.dev. ARD identifier: urn:air:io.github.spazio-genesi:mcp:attest-mcp-remote.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
