Why people use Cryptographic Action Attestor
Cryptographic Action Attestor stops invisible agent tampering
This Connector changes the game by making every entry part of a cryptographic chain. You can't just delete a line without breaking the entire hash sequence, which makes any tampering immediately obvious. You get a ledger that actually stands up to scrutiny.
What Vinkius changes
You get a verifiable, tamper-proof history of every autonomous decision.
Use it from Claude, ChatGPT, Cursor or another AI client you already have.

Before you connect
Questions about Cryptographic Action Attestor.
The practical details behind the request, access and result.
How does Cryptographic Action Attestor protect my logs?
It uses SHA-256 hashing to link every new entry to the previous one. This creates a chain where any modification to an old record breaks the entire sequence, making tampering easy to spot.
Can I use Cryptographic Action Attestor with Claude or Cursor?
Yes. Since it follows the Model Context Protocol, you can connect it to any compatible client like Claude, Cursor, or Windsurf through Vinkius.
Is the Cryptographic Action Attestor ledger permanent?
The ledger is append-only, meaning once an action is recorded, it cannot be removed or changed without invalidating the audit trail. This provides a permanent history of events.
How do I detect tampering using Cryptographic Action Attestor?
You can run a status check on your logs at any time. If anyone has attempted to alter the history, the integrity check will fail and alert you to the discrepancy.
Does Cryptographic Action Attestor support multiple agents?
Yes. You can use a single instance of this Connector to create a centralized, unified audit trail for all your different autonomous agents and workflows.
How does the server ensure the log hasn't been tampered with?
The server uses SHA-256 hashing to create a cryptographic fingerprint for every action. When you call get_audit_log_status, the system recomputes all hashes in the log and compares them against the stored values to detect any unauthorized changes.
What information is recorded during an attestation?
The attest_action capability records the name of the capability used, the specific parameters passed to it, and a Unix timestamp.
Can I see previous actions in the log?
Yes, you can use the history retrieval capabilities to view the sequence of recorded events in the ledger.
