Connect Mark and your agent gets 7 tools, among them create_account, create_proof, grant_access. It answers at https://makemark.io/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 1 of 6 times since 10 September 2026; the last check, on 19 October 2026, succeeded.
Mark: stamp files with a signed, timestamped provenance record. Hash locally; verify free.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
create_account | 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 Inputs: label |
create_proof | 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 pub Inputs: contentHash, contentType, title, visibility, previousProofId, canonicalSlug |
grant_access | 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. Inputs: proofId, granteeId |
list_proofs | List your recent stamps (requires API key). Inputs: limit |
reveal | 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 r Inputs: proofId, capabilityToken |
revoke_proof | Revoke a stamp you created (forward-only: anchored history stays verifiable, but the proof is marked revoked from now on). Requires API key. Inputs: proofId |
verify_proof | 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 Inputs: contentHash |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://makemark.io/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: dev.tatastu. Endpoint host: makemark.io. ARD identifier: urn:air:dev.tatastu:mcp:proof.
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.
