Install in OpenClaw
/install wecom
Description
Send messages to WeCom (企业微信) via webhooks using MCP protocol. Works with Claude Code, Claude Desktop, and other MCP clients.
Usage Guidance
Install this only if you want an agent to post into the configured WeCom chat. Keep the webhook URL secret, confirm the destination group, avoid sending secrets or confidential data unless intended, and prefer reviewed local files or verified npm provenance for installation.
Capability Analysis
Type: OpenClaw Skill
Name: wecom
Version: 1.0.3
The skill bundle provides a standard Model Context Protocol (MCP) server for sending text and markdown messages to WeCom (企业微信) via incoming webhooks. The implementation in src/index.ts and dist/index.js uses the axios library to perform POST requests to a user-defined WECOM_WEBHOOK_URL environment variable. The code logic is transparent, lacks any high-risk behaviors like unauthorized data exfiltration or shell execution, and the documentation in SKILL.md and README.md is strictly aligned with the tool's stated purpose.
Capability Assessment
Purpose & Capability
The code, README, SKILL.md, and skill.json consistently describe and implement sending text and markdown messages to WeCom via incoming webhooks.
Instruction Scope
The tools accept arbitrary caller-provided message content and mention lists, which is expected for a chat-sending integration; users should rely on client approval or workflow review before sending sensitive content.
Install Mechanism
Installation uses normal npm/TypeScript MCP commands, while README also suggests global npm or npx usage; users should verify package provenance if installing from the registry rather than the reviewed artifact.
Credentials
The required WECOM_WEBHOOK_URL is a posting credential and is proportionate to the integration, but it should be treated as a secret because anyone with it may post to the configured chat.
Persistence & Privilege
No artifact evidence shows hidden persistence, background self-starting, shell execution, local file access, credential harvesting, or unrelated privileged behavior.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install wecom - After installation, invoke the skill by name or use
/wecom - Provide required inputs per the skill's parameter spec and get structured output
