About Liquid
Liquid is an MCP server published by the GitHub account ertad-family. Connect your AI agent to anything — APIs, databases, and agents; read and write, auto-discovered.
It runs on your own machine: your AI client starts it from the PyPI package liquid-mcp at version 0.1.0.
It asks for 3 secrets: OPENAI_API_KEY, GEMINI_API_KEY and ANTHROPIC_API_KEY. Give it a key with the least access that still works.
Version 0.2.0 was published on 28 May 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 1 warn, 0 fail, 1 info. How we check.
