wechat — MCP server by Dcatfly/weixin_claude

wechat

wechat is an MCP server for Claude Code from Dcatfly/weixin_claude_code. Its token cost is not measured, scanned A, a copy of whatsapp, MIT.

A local MCP server configuration for WeChat, launched with Bun from the add-on's project directory.

In plain words

What is it for?: Starting the configured WeChat MCP server for use by a coding agent.
Why use it?: It provides the setup needed to start the server, but the input does not describe what WeChat data or actions it supports.

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: listed in a Claude config.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Part of the weixin_claude_code plugin — 1 MCP server shipped together

Good fit Starting the configured WeChat MCP server for use by a coding agent.

Installing this writes the configuration, not the program: `bun` runs a file from the repository, so clone it first and make the path in the command match where you put it.

Install

Getting it into your agent

This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Claude Code

/plugin marketplace add Dcatfly/weixin_claude_code

Claude Code

/plugin install weixin_claude_code

Installing this writes the configuration, not the program: `bun` runs a file from the repository, so clone it first and make the path in the command match where you put it.

Made for: Claude Code.

Or install weixin_claude_code, the plugin that ships this one along with the rest of its 1 MCP server.

Security

Grade A, and why

wechat scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

83% identical to whatsapp — 14 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
