Token Revoke MCP server

Let your AI check and cancel risky token permissions on your crypto wallet across many blockchains.

This is a small helper that connects your AI assistant to your crypto wallet's token permissions. It can list every app or contract that is allowed to spend your tokens, and it can cancel those permissions when you want. It is handy if you use crypto wallets and want to keep them tidy and safe.

What is an MCP server? The 30-second version

On its own, your AI can only chat. An MCP server is a small helper program that gives your AI a new skill or a connection to an app or service. This one connects your AI to your crypto wallet's token permissions across many blockchains. So when you ask your AI to check or cancel a permission, it can actually look it up and do it for you.

What this MCP server does

You ask your AI something like show me all the token permissions for my wallet on Polygon. Your AI uses this helper, which talks to a service called Moralis to fetch the list. The helper also knows how to send a cancel request to the blockchain when you ask it to. Then it tells you what it found or what it did, right in the chat.

Flow diagram: you ask your AI “Show my token permissions on Polygon”, the Token Revoke MCP server connects it to Moralis, and you get back list of permissions.

What you can do with it

List all token permissions for your wallet on a chosen blockchain
Show token names, balances, and the dollar value at risk for each permission
Cancel a specific token permission for a certain spender
Check if a cancel transaction went through
Work with over 50 blockchains, including Ethereum, Polygon, and BSC

Try asking your AI

“Show me all the token approvals for my wallet on Polygon.”
“Revoke the allowance for token 0x2791bca1f2de4661ed88a30c99a7a9449aa84174 to spender 0x1111111254eeb25477b68fb85ed929f73a960582 on BSC.”
“Did my transaction 0x123... on BSC go through?”
“List all approvals on Ethereum that are worth more than 100 dollars.”

What it gives back to you

You get a list of permissions with details like the token symbol, how much you hold, the dollar value at risk, and who can spend it. For a cancel request, you get a short message with a transaction hash and a note that it is not yet confirmed. When you check a transaction, you get a status like pending, successful, or failed, plus the block number if it is done.

Before you start

What you need

Node.js version 18 or higher
A Moralis API key (a kind of password for apps; you can get one from Moralis)
An Ethereum-compatible private key for your wallet (this is sensitive, keep it safe)

Good to know

This helper can send real transactions that cancel token permissions, and it needs your wallet's private key, so only use it with a wallet you are comfortable giving that access to.
