Overview

Web3Auth's official MCP server helps AI coding assistants integrate MetaMask Embedded Wallets (the Web3Auth SDK line). It serves live SDK documentation search, integration examples, and type lookups. An agent builder plugs it in so a coding agent can wire embedded-wallet auth into an app against current docs instead of stale training data.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.

Install — as documented by the project, not run by us

claude mcp add --transport http satohub-web3auth-mcp https://mcp.web3auth.io/

A remote server: your client connects to the project's endpoint. Installing runs third-party software under your own credentials. Sato Hub publishes the documented invocation and, where the harness reproduced it, the date it did — neither is a safety review.

Live probe verifies the interface responds — not what the tools do, their safety, or their output quality. The call is one read-only tool named by this server's own list (list_/get_/search_, no mutating verb anywhere in the name, no required arguments and none that look like a key, an address or an amount), asked once a day with no arguments. Not asked is not a failure.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden. 46 of these checks predate 2026-09-01, when the probe counted a bot-block (HTTP 403) as a failure and recorded no reason for any failure. Every one of them passed, so the rate covers them too.
