filefunction / class

Why would anyone build with this?

REASON 1

Calculate the exact storage slot for a namespaced ERC-7201 storage area in a smart contract.

REASON 2

Verify that a storage location in existing code matches the namespace that generated it.

REASON 3

Let an AI assistant like Claude or Cursor handle ERC-7201 storage math while writing Solidity.

REASON 4

Audit a smart contract's storage layout for compliance with the ERC-7201 standard.

How do you spin it up?

Difficulty · moderate Time to first run · 30min

Requires configuring an MCP-compatible AI assistant (Claude, Cursor, or Copilot) to run the server command.

Yoink these prompts

Prompt 1
Set up erc7201-mcp in Cursor so it can calculate ERC-7201 storage slots while I write Solidity.
Prompt 2
Ask my AI assistant to verify this storage location matches the ERC-7201 namespace I defined.
Prompt 3
Compute the storage slot for a namespace called 'MyContract.storage.v1' using erc7201-mcp.
Prompt 4
Explain how ERC-7201 namespaced storage works using erc7201-mcp's validation function.
