The listed licence is MIT. Check the upstream terms for permitted use and commercial requirements; a public repository does not by itself mean the software is free or open source. Connected APIs and hosted services may have separate charges.

What can Liveauth MCP Server do?

MCPVault has not yet recorded the tool list for Liveauth MCP Server; it is captured when the server passes a live MCP handshake. The description above is what the project publishes.

Liveauth MCP

Verified

by dulzuradev

Authentication, pay-per-call metering, budgets, and signed receipts for AI agents and MCP tools using proof-of-work, Lightning, and L402. Runs credential-free with PoW or connects to a LiveAuth project for production metering.

01 / Choose your client

02 / Before you connect

The maintainer declares that no authentication is required.

Install the runtime required by the project and make it available to your client.

Project instructionsEnvironment variable names (optional)

Use names from the project instructions, separated by commas. Enter names only, never secret values.

03 / Add the configuration

Source: maintainer launch command

claude mcp add --transport stdio 'liveauth-mcp' -- 'npx' '-y' '@liveauth-labs/mcp-server@1.3.1'

Run in your terminal after replacing any placeholders.

04 / Check it in your client

Open your client’s MCP settings and confirm the server connects and lists its tools. A copied configuration does not confirm a working connection.

Security profile

Exposure: Limited

Runs commands or loads code on your machine, but does not reach secrets or other agents.

What this server can reach, from a static read of the shipped code. Nothing was executed and nothing here is a verdict: a browser tool has to run commands and an API wrapper has to call its API. Decide what fits your setup.

NVIDIA SkillSpector v2.11.0, MCPVault MCP-server policy. Scanned 6 days ago @ 5a3d172.

Detected

Runs unpinned packages at runtime1 places
Executes npx or uvx without a version, so a compromised upstream release would run.

Not detected: reads environment variables in bulk, sends conversation content outward, runs shell commands, reads or writes other agents' configuration, accesses credential files, uses elevated privileges, installs itself to run later, matches a known malicious pattern.
