Waiting for input…

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

These prompts ship with the National Archives Catalog Connector. Once yours is connected, they work in your chats.

Mission Control

See everything your agents do in National Archives Catalog.

When your agents run a tool in National Archives Catalog, it happens on the client side: you see the answer in the chat, but not the request itself, what data it carried, or whether a rule was broken.

Now every move lands on your screen.

Every execution is recorded, enforced, and shown to you: what ran, what it returned, what was blocked, and why.

Request Volume & Latency

requests latency

Every request your agents make through National Archives Catalog is logged, enforced and auditable. See how AI Governance turns agent activity into accountability, and what it means for your National Archives Catalog workflows.

What sets us apart

It's not just the Connector that stays safe. Everything your agents do through it is.

Connecting National Archives Catalog to your AI is step one. But an open line between your agents and National Archives Catalog is only half the story: without protection, every action they take runs unguarded.

That's why protection doesn't stop at the door.

Every action your agents take through the Connector runs inside our infrastructure: signed activity logs, automatic key rotation, spending limits that pause instead of surprise, and a sandbox that isolates every execution.

01

Tamper Proof Activity Log

Every request your agents make in National Archives Catalog is recorded and signed, so any change to the history becomes detectable.

02

Automatic Key Rotation

We rotate security keys every 24 hours. Your National Archives Catalog connection stays protected without any manual work.

03

Spending Protection

We enforce the spending limit you choose and pause actions that exceed it until approval is received. Your National Archives Catalog actions never surprise you.

04

Isolated Sandbox

Every execution through National Archives Catalog runs isolated, with 34+ security rules covering memory, CPU, network access, file handling and execution.

05

Security Event Streaming

Security events flow to Splunk, Datadog or your own webhook, so National Archives Catalog activity lands in the tools you already rely on.

06

Instant Resume

Idle connections resume in 3 to 5 ms while preserving their state, keeping your conversations responsive across every client.

07

Malicious File Protection

We detect compressed files designed to exhaust system resources and block them before they ever reach National Archives Catalog.

08

Credential Validation

We test your National Archives Catalog credentials before saving them. Invalid credentials are rejected instead of being stored.

09

Separate Usage Limits

Usage stays isolated per account, so activity in one connection never consumes another account's allowance.

One Connector, one link, and the whole operation is protected. Not just the connection: everything your agents do through it.

These guarantees are not add-ons: they are the infrastructure every National Archives Catalog connection runs on. Read how our infrastructure protects everything your agents do, end to end.

FAQ

Claude access questions.

  • 01

    Does this work on claude.ai and in the Claude desktop app?

    Yes. You add the same link under Customize and Connectors in both, and your chats work the same in each.

  • 02

    If I connect National Archives Catalog to Claude, can I use the same connection in ChatGPT or Gemini later?

    Yes, and that's the point: the connection is yours, not Claude's. You paste the same link in any AI you use, and there's nothing new to set up or pay again. Connect a new AI and National Archives Catalog is already there.

  • 03

    Do I need to hand my National Archives Catalog password to Claude?

    Never. You sign in once at Vinkius, and we keep your logins encrypted and away from your AI. Claude only ever sees the link, and you can remove it whenever you want.

  • 04

    What can I actually ask Claude to do with National Archives Catalog?

    Whatever the Connector covers: check data, run actions and bring answers back into the chat. The Connector page lists every capability your AI gains, with real examples you can copy.

  • 05

    Claude doesn't show the Connector. What do I check?

    Make sure the link was pasted exactly as copied and that the Connector is active in your Vinkius account, then reopen the connectors list in Claude. A deactivated Connector stops appearing in new chats.

  • 06

    Can I remove the access later?

    Anytime. Remove the connector under Customize and Connectors in Claude and it's out of your chats. Your Vinkius account keeps the connection and its history either way, ready for the next AI.
