An MCP server for interacting with the Ethereum Name Service (ENS)
If you already use Ens, the ens mcp server is the piece that lets your assistant work with it directly. An MCP server for interacting with the Ethereum Name Service (ENS).
MCP Server for Ethereum Name Service (ENS), enabling Claude to interact with the ENS system to resolve names, check availability, retrieve records, and more.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
Prerequisites — The Prerequisites tool exposed by this serverInstallation — 1. Clone the repository or create a new project: bash git clone https://github.com/JustaName-id/ens-mcp-servermcp-server-ens on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.
Configuration is passed through the environment: PROVIDER_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Ens's toolset — Prerequisites, Installation — is a fair guide to whether it matches your workflow. It is maintained by JustaName-id; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
