Qwen Code + Nansen

One chat. Your Nansen, live inside Qwen Code.

Real prompts, answered with live data. This is the kind of session you will have in Qwen Code once the link is in.

Waiting for input…

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

These prompts ship with the Nansen Connector. Once yours is connected, they work in your sessions.

The full capability set, the prompts and the observed latency live on the Nansen Connector page.

Mission Control

See everything your Qwen Code agents do in Nansen.

When Qwen Code runs a tool in Nansen, it happens in your editor: you see the result, 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 Qwen Code agents make through Nansen is logged, enforced and auditable. See how AI Governance turns agent activity into accountability, and what it means for your Nansen workflows.

What sets us apart

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

Connecting Nansen to your AI is step one. But an open line between your agents and Nansen 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 Nansen is recorded and signed, so any change to the history becomes detectable.

02

Automatic Key Rotation

We rotate security keys every 24 hours. Your Nansen 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 Nansen actions never surprise you.

04

Isolated Sandbox

Every execution through Nansen 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 Nansen 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 Qwen Code sessions responsive.

07

Malicious File Protection

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

08

Credential Validation

We test your Nansen 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 Nansen connection runs on. Read how our infrastructure protects everything your Qwen Code agents do, end to end.

FAQ

Qwen Code access questions.

  • 01

    Does this work in the Qwen Code chat?

    Yes. Run /mcp in the chat to open the MCP dialog and see your server's tools, prompts and resources. If Qwen Code was already running, restart it in the same project.

  • 02

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

    Yes, and that's the point: the connection is yours, not Gemini'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 Nansen is already there.

  • 03

    Do I need to hand my Nansen password to Gemini?

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

  • 04

    What can I actually ask Gemini to do with Nansen?

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

  • 05

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

    Run qwen mcp list or open the /mcp dialog, confirm the url was pasted exactly as copied, and confirm the Connector is active in your Vinkius account. If Qwen Code was already running, restart it in the same project.

  • 06

    Can I remove the access later?

    Run qwen mcp remove and it's out of your sessions. Your Vinkius account keeps the connection and its history either way, ready for the next AI.

About the Connector

What Nansen adds to your AI.

Once you connect it, your AI gains 48 capabilities: the exact actions it can take in Nansen when you ask. The Connector page lists every one of them in detail, alongside the latency we measure in production and prompts worth trying first.
