Readme
ownerwatch logo
ownerwatch-mcp
A Model Context Protocol server that lets a coding agent answer "who controls this contract?" for any EVM address. It walks owners, proxy upgrade admins, beacons, EIP-2535 diamonds (upgradeable through diamondCut, an upgrade path no proxy slot reveals — so most tools read a diamond as immutable), Safes (signers, threshold, modules, transaction guard), timelocks (delay), AccessControl and AccessManager roles, and flags EOAs, 1-of-N Safes and powers held without a timelock.
It is built on ownerwatch and runs over stdio on your machine. Every tool is read-only: no key, no wallet, no account, and nothing is ever sent on-chain.
