With MCP1
Etherscan for the whole team, behind one URL
- 01
Install it once
An admin adds Etherscan from the MCP1 catalog. Its authentication or token stays sealed in MCP1, never on a laptop.
- 02
Decide who gets what
Open it to groups, fully or read-only, and set rules per tool. Destructive tools can need an admin.
- 03
Connect any client
Claude, Cursor, ChatGPT, Codex and the rest connect one gateway URL and sign in with their own account.
