This MCP server provides Ethereum validation and cryptographic utilities, including address and private key validation, EIP-55 checksum conversion, address derivation, signature checks, and function selector encoding/decoding. It also includes ENS name validation, Keccak-256 hashing, vanity checks, and storage slot calculation.

Install & configure
Prerequisites
- requiredInstall the packageInstall the MCP server package from the project source as documented in the README.
$ pip install -e .
Install in your client
Paste into the AI you're chatting with — it will figure out the rest
Please install the `validation-mcp-server` MCP server into my current AI client (that's you).
Required prerequisites (do these first if not already done):
- **Install the package** — Install the MCP server package from the project source as documented in the README. Run: `pip install -e .`
Canonical MCP server config (stdio transport):
- command: `validation-mcp-server`
- args: []
Note: The README shows a stdio MCP server launched via the `validation-mcp-server` executable. No environment variables or additional runtime arguments are documented.
Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.Note: The README shows a stdio MCP server launched via the `validation-mcp-server` executable. No environment variables or additional runtime arguments are documented.
