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 only if you intend agents to post content into a WeCom group. Do not send secrets, personal data, or internal material unless that WeCom channel is approved for it, keep WECOM_WEBHOOK_URL out of logs and repositories, and prefer pinned/local dependency execution with updated packages.
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
Credentials
The only required secret-like value is WECOM_WEBHOOK_URL, which is proportionate for a webhook sender but should be protected as a credential.
Install Mechanism
Installation uses standard npm commands with no custom install hooks observed; however, examples and metadata include unpinned npx/ts-node usage, and the lockfile confirms several scanner-flagged dependency versions.
Instruction Scope
The documentation and tool names disclose external WeCom sending, but they do not prominently warn that message content leaves the local environment.
Persistence & Privilege
No persistence, background service installation, privilege escalation, local file harvesting, or memory modification behavior was found.
Purpose & Capability
The stated purpose is WeCom webhook messaging, and the code implements three MCP tools that send caller-provided text or markdown to the configured webhook.
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
