Real details out. Stand-ins in.
```
POST /v1/redact
{ "text": "Customer: Marta Kowalczyk, card 4111 1111 1111 1111" }

→ "Customer: Sylvie Nakashima, card 4024 0071 3421 9888"
```
Redact
Real details out. Stand-ins in.
No session and no SDK. Send text and get it back with names, emails, phone numbers, addresses, cards and account numbers swapped for believable stand-ins, plus a map of what was swapped.

Restore
And back again.
```
POST /v1/restore
"Tell Sylvie Nakashima…"
→ "Tell Marta Kowalczyk…"
```
Restore
And back again.
Send the model's reply and the map to /v1/restore, and the real names, numbers and addresses go back in. The map stays with you; Secure AI keeps no copy.

Drop-in Proxy
Already using an OpenAI client? Change one line.
Point your existing client at /v1/proxy. Details are taken out on the way through and put back in the reply, using your own model key. Tool calls work too: results are hidden like everything else, and each call comes back with the real values, checked against your rules first.

Agents that speak MCP reach the same controls as tools at /mcp: hide details, put them back, and check an action before it runs. Building your own MCP server? Start from create-secure-mcp.

Quick start

Inspect
Every action, judged before it runs.
Inspect
Every action, judged before it runs.
/v1/inspect judges whether an action may happen at all. Send the tool call your agent was about to make; the decision comes from rules held on your account, not from anything in the request. Approve waits for a person.
Guard
Wrap a function. It runs safely, or not at all.
```
const send = sai.guard(
  "email.send", mailer.send);
```
Guard
Wrap a function. It runs safely, or not at all.
The SDK wraps a function your agent already calls and runs it with the rewritten arguments, so protection does not depend on anybody remembering to check a decision. A refusal throws.
What It Finds
Finds what's personal. Even without a label.
What It Finds
Finds what's personal. Even without a label.
A number with no label, like “payment from 10972500”, is read in its sentence and taken out when it is an account, an ID or a place. You can add any term of your own.
Rules
Start from PCI, HIPAA or GDPR.
Rules
Start from PCI, HIPAA or GDPR.
Rules per kind of data, per tool and per direction, starting from a template rather than an empty file. Allow your own domain once, for every agent.
Approvals
A person decides.
Approvals
A person decides.
An action a rule holds waits in Approvals. If nobody answers in time, the action is denied.
Audit Log
Everything your agents did. None of the details.
Audit Log
Everything your agents did. None of the details.
Kinds and locations of what was found, the decision and the tool, never the values themselves.
Gateway
Every request, checked on the way out.
Gateway
Every request, checked on the way out.
Point an HTTP client at /v1/gateway/<url> and every request gets the same inspection on its way out.
