Etherscan MCP Tool

This tool provides functionality to interact with blockchain data, specifically to retrieve the total supply of a token on a given chain, retrieve the chain ID for a given chain name, and retrieve a filtered list of RPC endpoints for a given chain ID.

Usage

The tool exposes the following functionalities:

• Get Total Supply: Retrieves the total supply of a token given its address and chain ID.
• Get Chain ID: Retrieves the chain ID for a given chain name.
• Get Filtered RPC List: Retrieves a filtered list of RPC endpoints for a given chain ID.

Get Total Supply

To get the total supply of a token, you need to provide the chain ID and the token address.

Parameters:

• chain_id: The ID of the blockchain network.
• token_address: The address of the token.

Example:

To find the total supply of token 0x6B2a01A5f79dEb4c2f3c0eDa7b01DF456FbD726a on chain 56, you would use the following:

{
  "chain_id": 56,
  "token_address": "0x6B2a01A5f79dEb4c2f3c0eDa7b01DF456FbD726a"
}

The tool would then return the total supply of the token, such as:

46141292590

Get Chain ID

To get the chain ID, you need to provide the chain name.

Parameters:

• chain_name: The name of the blockchain network.

Example:

To find the chain ID for BNB Smart Chain Mainnet, you would use the following:

{
  "chain_name": "BNB Smart Chain Mainnet"
}

The tool would then return the chain ID, such as:

56

Get Filtered RPC List

To get a filtered list of RPC endpoints, you need to provide the chain ID. You can also filter by isOpenSource and tracking.

Parameters:

• chain_id: The ID of the blockchain network.
• isOpenSource (optional): Filter by isOpenSource.
• tracking (optional): Filter by tracking (none, yes, limited, unspecified).

Example:

To find the RPC list for chain ID 1, you would use the following:

{
  "chain_id": "1"
}

The tool would then return the RPC list for chain ID 1.
