About weapp-agent-mcp

weapp-agent-mcp is an MCP server published by the GitHub account Chaixueyuan. Agent-first MCP server for WeChat Mini Program debugging & automation via WeChat DevTools.

It runs on your own machine: your AI client starts it from the npm package @chaixueyuan/weapp-agent-mcp at version 0.4.8.

It asks for 2 secrets: WEAPP_AUTO_ACCOUNT and WEAPP_DEVTOOLS_TICKET. Give it a key with the least access that still works.

Version 0.4.8 was published on 1 July 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, 0 warn, 0 fail, 2 info. How we check.
