✓ Watched since 2026-06-03 — behavioral baseline locked. We re-check this server's tool surface on a schedule; if it adds, removes, or silently rewrites a tool (rug-pull), we record it.

What it offers — 5 tools · Developer Tools

search_docs

Search MetaMask Embedded Wallets (Web3Auth) documentation and examples. Use for SDK discovery, feature lookup, and finding relevant examples. Returns

get_doc

Fetch the full content of a MetaMask Embedded Wallets documentation page. Use after search_docs to read the actual doc. Tries Algolia, then llms.txt,

get_example

Fetch the complete source code of a Web3Auth integration example from GitHub. Returns all source files needed to understand how the integration works.

get_sdk_reference

Fetch SDK source code (type definitions, interfaces, hooks) from the open-source Web3Auth SDK repos. Use for REFERENCE and DEBUGGING only — to verify

search_community

Search or fetch posts from the MetaMask Embedded Wallets community forum (builder.metamask.io). Use for troubleshooting real user issues, finding work

Observed behavior

No proxied traffic observed for this host yet. Connect it at /connect and its grade gains a measured Reliability score + per-tool behavioral evidence — the half a static scan can't produce.

Findings

No blocking issues found in the static + spec checks.

Grade another server

We re-grade mcp.web3auth.io on a schedule and alert your Slack/webhook the moment its tools change or its grade drops — rug-pull insurance for the connection.

Share this report card

A 1200×630 card with the grade + audit — drop it in a post, Slack, or your repo.

Embed this grade

A live badge — it re-verifies itself and shows current stability. Static scorecards can't. Paste it in your README or site to show users you're independently audited.

Agents: check this before connecting

Add the wmcp.sh trust oracle as an MCP server and call grade_mcp_server / check_mcp_drift in your agent's pre-connection gate:

How this grade is computed. An open, independent rubric — Spec conformance (20%), Security mapped to the OWASP MCP Top 10 (30%), Reliability (20%), Tool hygiene (15%), Transparency (15%) — run by connecting to the server and inspecting its real MCP surface. The grade is free and identical whether or not the operator pays. v1 uses static + spec signals from a single connection; continuous uptime, real latency, and annotation-truthing (declared readOnly vs observed behavior) layer on via the wmcp.sh proxy.
