What AI agents can do with Cryptographic Action Attestor: 2 tools for secure auditing
Securely record and verify every action taken by your autonomous agents.
Attest action
Records an event by computing a SHA-256 hash and appending it to the log. This creates a permanent, tamper-proof audit trail for any specific action.
Get audit log status
Checks the current integrity and total size of your audit log. Use this to quickly verify that no part of your history has been altered.
One MCP enables access. Vinkius turns MCPs into production-ready infrastructure.
You're looking at one of 5,800+ managed MCPs. The real value isn't the catalog. It's the control plane that secures, governs, audits, and manages every interaction between your agents and the tools they use.
No Shadow AI
Every agent action is visible, approved, and auditable. Nothing runs outside your governance.
Absolute agent control
Fine-grained permissions for every agent, MCP, and tool. Instantly revoke access and audit every execution.
Cost control per token
Spend broken down to the token, tool, and agent. Budgets and hard limits. No surprise invoices.
Managed & monitored infra
We operate the runtime, authentication, scaling, retries, and monitoring. Your team manages AI, not infrastructure.
Data protection, DLP by design
Sensitive data is filtered before reaching the model. Access is governed so agents receive only the information they're allowed to use.
Token optimization, real savings
Lower AI costs by delivering the right context instead of unnecessary tools. Better accuracy, faster responses, and fewer wasted tokens.
Cryptographic Action Attestor stops invisible agent tampering
Security engineers and DevOps leads who cannot afford 'ghost' changes in their automated pipelines.
Security Engineer
Verifies that agent actions match authorized requests during security audits.
DevOps Lead
Ensures deployment logs haven't been altered after a production rollout.
Compliance Officer
Maintains an immutable trail of activity for regulatory reporting requirements.
Frequently Asked Questions
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 MCP 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 tool records the name of the tool 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 tools to view the sequence of recorded events in the ledger.
