Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

A futuristic MCP client docking bay
V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Automate a task

Put Lit Protocol to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

Lit Protocol works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Lit Protocol to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Connect your client

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 20 capabilities arrive ready to run.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Lit Protocol, so you can see the experience inside your AI.

It does not authenticate your account with Lit Protocol. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

Who it's for

Built for the work Lit Protocol owners hand off.

This MCP is built for technical users working within the Web3 and decentralized security space.

  • 01

    Web3 Developers

    Automate PKP and Lit Action management directly from your coding environment.

  • 02

    Security Engineers

    Audit access control groups and manage usage keys using natural language.

    Test and run decentralized logic in TEEs to verify application behavior.

FAQ

Questions Lit Protocol owners ask.

  • 01

    How do I use this MCP with my AI client?

    Once you subscribe on Vinkius, you connect your client like Claude or Cursor once. From there, the capabilities are immediately available to your agent.

  • 02

    What are PKPs?

    Programmable Key Pairs (PKPs) are decentralized wallets that act as identities within the Lit Protocol ecosystem.

  • 03

    Can I run custom code?

    Yes, you can use the execute_lit_action capability to run JavaScript code or use an IPFS CID within a TEE.

  • 04

    How do I handle billing?

    The MCP includes capabilities to check your balance, create payment intents via Stripe, and confirm payments to top up credits.

  • 05

    Is the execution secure?

    Lit Actions run inside Trusted Execution Environments (TEEs), which provides a secure and isolated space for your code.

  • 06

    Can I execute custom JavaScript code securely within a TEE?

    Yes! Use the execute_lit_action capability. You can provide either inline JavaScript code or an IPFS CID to run immutable programs inside Lit's Trusted Execution Environments.

  • 07

    How do I see all the decentralized wallets (PKPs) associated with my account?

    Simply use the list_wallets capability. It will return all Programmable Key Pairs (PKPs) owned by your account, including their IDs and addresses.

  • 08

    Is it possible to organize access control by grouping different identities?

    Absolutely. You can use add_group to create a new group and then add_pkp_to_group to manage which decentralized identities belong to that specific access schema.
