/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 your agent to post selected content into WeCom. Do not send secrets, credentials, regulated data, or private prompts through it unless that is approved, and keep WECOM_WEBHOOK_URL out of logs, screenshots, and source control. Prefer a version with updated dependencies and a lockfile.
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 described capability is narrowly aligned with the stated purpose: an MCP server for sending text and markdown messages to WeCom through a user-supplied webhook URL.
Instruction Scope
The tool accepts arbitrary message content, so users should understand that anything sent through it leaves the local agent environment and is posted to WeCom; the scanner concern is valid as guidance but not evidence of hidden behavior.
Install Mechanism
The package uses normal Node dependencies for an MCP server and HTTP client. The reported caret dependency ranges and vulnerability advisories are supply-chain maintenance issues, not artifact-backed malicious behavior.
Credentials
Network access to the configured WeCom webhook and use of WECOM_WEBHOOK_URL are proportionate to the messaging function.
Persistence & Privilege
No evidence indicates persistence, privilege escalation, shell execution, credential-store reading, broad file access, or automatic background operation. The webhook URL itself should be treated as a secret.
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
