Let AI agents act on sensitive data —
without ever reading it.
ASTIS exposes encryption, signing, tokenization, and audit to AI agents over the Model Context Protocol — so agents in your products and workflows can operate on regulated data while business-payload plaintext never reaches the model.
Infrastructure access shouldn't mean model access to your plaintext.
Where agents meet sensitive data
Anywhere an AI agent must operate on regulated or confidential data — but the model should never see it in clear.
Regulated AI workflows
Agents process personal, health, or payment data without that plaintext ever reaching the LLM or a third-party model — supporting GDPR data minimisation and EU AI Act data governance, even when the model is hosted outside the EU.
Agentic apps & copilots
Embed crypto in your AI features — the model acts on sensitive data through tools, ASTIS holds the plaintext boundary.
AI coding agents
Claude Code, Cursor, and Windsurf integrate ASTIS faster with dev-time tooling — endpoint reference, starter code, static checks.
Automation pipelines
Agents sign, tokenize, and verify across steps; trust travels with the artifact, not the plaintext.
Two modes
Dev-time tooling on the hosted server, and runtime crypto self-hosted in your own infrastructure.
Hosted at mcp.astis.io
Coding agents get tooling to ship ASTIS integrations faster — no secrets, no runtime crypto, just reference and scaffolding.
Self-hosted in your infrastructure
Agents call real cryptographic operations from a deployment inside your own infrastructure — keys and decryption stay with you.
Why teams trust agents with it
Business-payload-blind
Agents get cryptographic tools, not plaintext. Business-payload plaintext never reaches the model — ZK-MCP by design.
Customer-controlled keys
With HYOK CVS, key custody and decryption authority stay on your infrastructure.
Scoped & audited
Runtime access is opt-in and scoped; every cryptographic operation lands in a tamper-evident audit trail.
How ASTIS maps to the EU AI Act
For AI systems handling personal or sensitive data, keeping plaintext out of the model supports several EU AI Act obligations. ASTIS is designed to support these controls — it is not an AI Act conformity assessment, and obligations fall on the AI system's provider or deployer.
Keep personal data out of the model
Art. 10 · data & data governance
ASTIS encrypts or format-preserves data before it reaches the LLM — supporting data-governance and minimisation across your AI data flows.
Logged, exportable evidence
Art. 12 · record-keeping / logging
A tamper-evident audit trail of the cryptographic operations an agent performs — evidence of what was accessed, when, and by which key.
Harden the data layer
Art. 15 · accuracy, robustness & cybersecurity
Encryption and customer-controlled keys protect the data your AI system depends on; the business-payload-blind edge reduces the attack surface.
No EU plaintext to a non-EU model
GDPR interplay · Chapter V transfers
The AI Act doesn’t replace GDPR. Keeping plaintext out of the model means EU personal data isn’t transferred to a non-EU LLM in clear — even when the model is hosted outside the EU.
Give your agents crypto, not your plaintext.
