LangChain + Svix

One agent. Your Svix, live inside LangChain.

Real prompts, answered with live data. This is the kind of session your agent will run once the adapter is in.

Waiting for input…

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

These prompts ship with the Svix Connector. Once yours is connected, your agent can run them.

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

Mission Control

See everything your LangChain agents do in Svix.

When your LangChain agent runs a tool in Svix, it happens inside your code: you see the output, 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 LangChain agents make through Svix is logged, enforced and auditable. See how AI Governance turns agent activity into accountability, and what it means for your Svix workflows.

What sets us apart

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

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

02

Automatic Key Rotation

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

04

Isolated Sandbox

Every execution through Svix 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 Svix 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 LangChain sessions responsive.

07

Malicious File Protection

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

08

Credential Validation

We test your Svix 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 Svix connection runs on. Read how our infrastructure protects everything your LangChain agents do, end to end.

FAQ

LangChain access questions.

  • 01

    Which LangChain version supports this?

    LangChain 1.4.0 or newer with the mcp extra (pip install langchain[mcp]). The MCPAdapter lives in the langchain.mcp namespace and is currently in beta.

  • 02

    If I connect Svix to my LangChain agent, can I use the same connection in Claude or ChatGPT later?

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

  • 03

    Do I need to hand my Svix password to my agent?

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

  • 04

    What can my agent actually do with Svix?

    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

    The tools don't show up. What do I check?

    Confirm the URL matches your link exactly and that the Connector is active in your Vinkius account, then call list_tools again. A deactivated Connector stops responding.

  • 06

    Can I remove the access later?

    Anytime. Remove the MCPAdapter call from your code and the tools leave your agent. Your Vinkius account keeps the connection and its history either way, ready for the next AI.

About the Connector

What Svix adds to your AI.

Once you connect it, your AI gains 15 capabilities: the exact actions it can take in Svix 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.
