MCP tools · 8 exposed · ~1,536 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
attest_hash ~426

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 normalized and BOUND by the signature — immutable after issuance, but they remain self-declared (they don't prove authorship). Compute the SHA-256 locally if you have code execution (`sha256sum <file>` / `shasum -a 256 <file>` / `certutil -hashfile <file> SHA256`). NEVER send file bytes or base64 through tool arguments: this server never receives files. If you cannot compute a hash locally, point the user to the website (https://attestazione.spaziogenesi.org, full privacy: hashing happens in the browser) or the Telegram bot @SGAttestBot.

NameTypeReqDescription
annostring–Declared year/version (bound by the signature).
autorestring–Declared author (bound by the signature).
namestring–File name (descriptive only, shown on the certificate).
notestring–Declared notes (bound by the signature).
sha256stringyesSHA-256 fingerprint of the work: 64 hexadecimal characters. Compute the SHA-256 locally if you have code execution (`sha256sum <file>` / `shasum -a 256 <file>` / `certutil -hashfile <file> SHA256`).…
sizeinteger–File size in bytes (descriptive only).
titolostring–Declared title of the work (bound by the signature).
typestring–MIME type (descriptive only).

No output schema declared.

No examples provided.

authorize ~77

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`. Not needed if the connection already carries an API key header, or for verification tools.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

check_anchor ~175

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.

NameTypeReqDescription
sha256stringyesSHA-256 fingerprint of the work: 64 hexadecimal characters. Compute the SHA-256 locally if you have code execution (`sha256sum <file>` / `shasum -a 256 <file>` / `certutil -hashfile <file> SHA256`).…

No output schema declared.

No examples provided.

complete_authorization ~40

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.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

create_certificate_pdf ~197

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 links (the PDF itself is downloadable from its URL — it is never inlined here).

NameTypeReqDescription
sha256stringyesSHA-256 fingerprint of the work: 64 hexadecimal characters. Compute the SHA-256 locally if you have code execution (`sha256sum <file>` / `shasum -a 256 <file>` / `certutil -hashfile <file> SHA256`).…

No output schema declared.

No examples provided.

lookup_certificate ~188

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 information is reachable only by whoever knows the fingerprint.

NameTypeReqDescription
sha256stringyesSHA-256 fingerprint of the work: 64 hexadecimal characters. Compute the SHA-256 locally if you have code execution (`sha256sum <file>` / `shasum -a 256 <file>` / `certutil -hashfile <file> SHA256`).…

No output schema declared.

No examples provided.

service_status ~57

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.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

verify_attestation ~376

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 only. Whether a given file matches the fingerprint must be checked locally by re-hashing the file. If the certificate carried declared metadata (title/author/year/notes), they must be provided EXACTLY as printed for the signature to verify.

NameTypeReqDescription
annostring–Declared year/version, exactly as printed (only if the certificate shows it).
attestazionestringyesThe attestation string exactly as printed on the certificate: "SHA-256:<hash>@<ISO timestamp>Z"
autorestring–Declared author, exactly as printed (only if the certificate shows it).
hmacstringyesThe server HMAC signature exactly as printed on the certificate (base64, 44 characters ending with '=').
notestring–Declared notes, exactly as printed (only if the certificate shows them).

Install

How do I install the io.github.SPAZIO-GENESI/attest-mcp-remote server?

io.github.SPAZIO-GENESI/attest-mcp-remote is a hosted endpoint at https://attest-mcp-remote.it-e3f.workers.dev/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

Common questions

What is the io.github.SPAZIO-GENESI/attest-mcp-remote server?

io.github.SPAZIO-GENESI/attest-mcp-remote is listed in the public MCP registry as io.github.SPAZIO-GENESI/attest-mcp-remote. Zero-install remote MCP server for proof-of-existence file attestation. This page covers its hosted endpoint (https://attest-mcp-remote.it-e3f.workers.dev/mcp).

Is the io.github.SPAZIO-GENESI/attest-mcp-remote server safe to use?

io.github.SPAZIO-GENESI/attest-mcp-remote scores 18 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the io.github.SPAZIO-GENESI/attest-mcp-remote server expose?

io.github.SPAZIO-GENESI/attest-mcp-remote exposes 8 tools: service_status, check_anchor, verify_attestation, lookup_certificate, authorize, and 3 more. Their descriptions and schemas cost roughly 1,536 tokens of context every time the server is loaded.

Does the io.github.SPAZIO-GENESI/attest-mcp-remote server require authentication?

Its publisher declares no required credentials for io.github.SPAZIO-GENESI/attest-mcp-remote. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.

Is the io.github.SPAZIO-GENESI/attest-mcp-remote server still maintained?

io.github.SPAZIO-GENESI/attest-mcp-remote is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
