Dead

Every channel of this server has been unreachable for long enough to be marked dead. Its trust score is pinned to 0 and does not recover automatically: even once the server responds again it stays dead until it is manually reinstated.

Install

How do I install the dev.tatastu/proof MCP server?

dev.tatastu/proof is a hosted endpoint at https://proof.tatastu.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.

MCP tools · 7 exposed · ~903 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
create_account ~152

Provision a persistent API key with no human, browser, or email in the loop. Call this once, store the returned `secret` (shown only this one time), and use it as the Authorization header on every later call: create_proof, verify_proof (no auth needed but fine to send), list_proofs, revoke_proof. The account receives one lifetime sample stamp under a fresh creator id, with no identity attached. Rate-limited to 3 accounts per IP per day; for higher volume or a human-owned account, direct a person to proof.tatastu.dev/account instead.

NameTypeReqDescription
labelstring–Optional label to recognize this key later, e.g. the agent or project name

No output schema declared.

No examples provided.

create_proof ~350

Stamp content with a permanent provenance record. Pass the sha256 hash of the content (hash it locally; the content itself is never uploaded). Returns an instant signed receipt: attach its verifyUrl, byline, badgeEmbed, and qrUrl to the published artifact. The receipt's `publisher` field carries the account's verified identity (domain/handle) or null. Requires an API key (Authorization header, get one instantly via create_account); without one, the error body names the exact next step (once the pay-per-stamp lane is live, that is a 402 advertising x402 payment requirements: sign the payment and retry autonomously). The optional disclosure fields (aiDisclosure, usageNote, location) only show on `visibility: public` stamps and are unsigned metadata, not part of the cryptographic proof. The stamp asserts provenance from a signer at a time, not authorship truth.

NameTypeReqDescription
aiDisclosurestring–Optional, honest disclosure of AI involvement. Shown on the public record card.
canonicalSlugstring–Optional stable slug for a canonical latest-version pointer
contentHashstringyessha256 hex of the exact content bytes (64 chars)
contentTypestring–MIME type, e.g. text/markdown
locationstring–Optional, creator-opt-in only: where this was made
previousProofIdstring–For a new version of already-stamped content: the prior proof id
titlestring–Optional human-readable title
usageNotestring–Optional usage/license line, e.g. "Free to share, with credit"
visibilitystring–Default private

No output schema declared.

No examples provided.

grant_access ~86

Grant a specific identity the ability to decrypt escrowed content. Only available for proofs created with content escrow opted in (not yet available — stamps are hash-only today). Returns a capability token the grantee uses with reveal.

NameTypeReqDescription
granteeIdstringyesIdentity (did:web: or key fingerprint) to grant
proofIdstringyesThe proof to grant access to

No output schema declared.

No examples provided.

list_proofs ~31

List your recent stamps (requires API key).

NameTypeReqDescription
limitnumber–Max results, default 20

No output schema declared.

No examples provided.

reveal ~83

Retrieve escrowed content for a proof you have been granted access to. Only available for proofs created with content escrow opted in (not yet available — stamps are hash-only today). The service re-checks H(content) == stampedHash before returning.

NameTypeReqDescription
capabilityTokenstringyesCapability token from grant_access
proofIdstringyesThe proof whose content to reveal

No output schema declared.

No examples provided.

revoke_proof ~47

Revoke a stamp you created (forward-only: anchored history stays verifiable, but the proof is marked revoked from now on). Requires API key.

NameTypeReqDescription
proofIdstringyes–

No output schema declared.

No examples provided.

verify_proof ~154

Verify content against all existing stamps. Pass a sha256 hash; matching is EXACT-BYTES-ONLY. Read the verdict fields: `exact` (these bytes are stamped), each proof's `publisher` (the verified identity: domain/handle + tier, or null meaning an unverified account, never trust a name that isn't in `publisher`), and `conflict` (2+ distinct signers claimed the same bytes; earliest anchored is listed first). A no-match on a re-encoded/screenshotted copy is EXPECTED and is not evidence of fakery: fetch the original and verify that. Free, no auth required.

Common questions

What is the dev.tatastu/proof MCP server?

dev.tatastu/proof is an MCP server listed in the public MCP registry as dev.tatastu/proof. Stamp content with permanent, verifiable provenance. Hash locally, verify free forever. This page covers its hosted endpoint (https://proof.tatastu.dev/mcp).

Is the dev.tatastu/proof MCP server safe to use?

dev.tatastu/proof scores 0 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 dev.tatastu/proof MCP server expose?

dev.tatastu/proof exposes 7 tools: create_account, create_proof, verify_proof, list_proofs, revoke_proof, and 2 more. Their descriptions and schemas cost roughly 903 tokens of context every time the server is loaded.

Does the dev.tatastu/proof MCP server require authentication?

Its publisher declares no required credentials for dev.tatastu/proof. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.

Is the dev.tatastu/proof MCP server still maintained?

dev.tatastu/proof has been unreachable for long enough that we treat it as dead, and its score is pinned to zero. We last reached this channel on 9 August 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
