Search MetaMask Embedded Wallets (Web3Auth) documentation and examples. Use for SDK discovery, feature lookup, and finding relevant examples. Returns doc page links with snippets and matching example projects.
AI agents call search_docs to retrieve information from MetaMask Embedded Wallets MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
chain | string | — | Filter examples by blockchain family |
query | string | — | What you are looking for -- e.g. 'React custom auth', 'Android deep linking', 'JWT grouped connections' |
category | string | — | Filter examples by category |
platform | string | — | Filter examples by platform |
Parameters from the server's own tool schema.
Even though search_docs only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Risk signalsAccepts freeform code/query input (query)
Documented attack patterns abuse exactly the kind of access search_docs gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MetaMask Embedded Wallets MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for search_docs:
{
"version": "1",
"default": "deny",
"tools": {
"search_docs": {}
}
}search_docs is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search MetaMask Embedded Wallets (Web3Auth) documentation and examples. Use for SDK discovery, feature lookup, and finding relevant examples. Returns doc page links with snippets and matching example projects. It is categorised as a Read tool in the MetaMask Embedded Wallets MCP MCP Server, which means it retrieves data without modifying state.
search_docs accepts 4 parameters: chain, query, category, platform. The full parameter table on this page comes from the server's own tool schema.
Register the MetaMask Embedded Wallets MCP server in PolicyLayer and add a rule for search_docs: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MetaMask Embedded Wallets MCP. Nothing to install.
search_docs is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the search_docs rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for search_docs. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
search_docs is provided by the MetaMask Embedded Wallets MCP server (web3auth/integrate). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
