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.

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.

02

Contract Debugging

Use the agent to read contract states or query historical events to verify logic.

03

Solana Token Swapping

Instruct your agent to get swap quotes and execute token swaps on the Solana Mainnet.

04

User Activity Auditing

Ask your agent to list transactions or search for specific user details to monitor engagement.

Automate a task

Put ThirdWeb 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

ThirdWeb 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 ThirdWeb 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. 29 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 ThirdWeb, so you can see the experience inside your AI.

It does not authenticate your account with ThirdWeb. 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 ThirdWeb owners hand off.

This MCP is built for professionals working at the intersection of AI and blockchain.

  • 01

    Web3 Developers

    They use the agent to prototype contract interactions and test auth flows in their IDE.

  • 02

    DApp Operators

    They hand off user profile management and event monitoring to the agent.

  • 03

    Product Managers

    They use the agent to query on-chain data and user details to track platform activity.

FAQ

Questions ThirdWeb owners ask.

  • 01

    How do I connect this MCP to my AI client?

    You connect once through your MCP-compatible client like Claude or Cursor. Vinkius hosts the MCP, so you just need to provide your ThirdWeb credentials to get started.

  • 02

    Which blockchains are supported?

    The MCP supports multiple chains, including specific deep integration for Solana operations like swapping and signing.

  • 03

    Can I use this to manage user logins?

    Yes, the MCP includes capabilities for email, SMS, social, and passkey authentication, as well as linking those identities to wallets.

  • 04

    Do I need to write code to interact with smart contracts?

    No, you can use natural language to tell your agent to read from or write to contracts using the provided capabilities.

  • 05

    Is my ThirdWeb API key secure?

    Vinkius manages your credentials and keeps the connection running securely so you don't have to manage local environment variables manually.

  • 06

    Can I read data from a smart contract without paying gas?

    Yes! Use the read_contract capability. It performs read-only calls (multicall) to the blockchain, which do not require gas or state changes.

  • 07

    How do I start an authentication flow for a new user?

    You can use the initiate_auth capability by specifying the method (email, sms, etc.) and the user's identifier. Then, use complete_auth with the verification code to finish the login.

  • 08

    Can I find a user's profile if I only have their wallet address?

    Absolutely. Use the get_user_details capability and provide the address parameter. The agent will return any associated user IDs, emails, or phone numbers linked to that wallet in your project.
