验证安装

which mail-mcp
# 应输出: /home/xxx/.local/bin/mail-mcp

配置

mcporter 配置

~/.mcporter/mcporter.json 中添加:

{

常见邮箱配置

邮箱 IMAP SMTP 备注
Gmail imap.gmail.com:993 smtp.gmail.com:465 需要 App Password
阿里云企业邮箱 mail.qiye.aliyun.com:993 smtp.qiye.aliyun.com:465
腾讯企业邮箱 imap.exmail.qq.com:993 smtp.exmail.qq.com:465

使用示例

mcporter 调用

# 列出文件夹
mcporter call mail-mcp.list_folders

# 搜索邮件
mcporter call mail-mcp.search_emails --args '{"folder": "INBOX", "limit": 10}'

# 发送邮件
mcporter call mail-mcp.send_email --args '{
  "to": ["[email protected]"],
  "subject": "测试邮件",
  "body_text": "这是邮件内容"
}'

# 发送带附件的邮件
mcporter call mail-mcp.send_email --args '{
  "to": ["[email protected]"],
  "subject": "带附件的邮件",
  "body_text": "请查收附件",
  "attachments": [{
    "filename": "report.pdf",
    "content_type": "application/pdf",
    "data_base64": "JVBERi0xLjQK..."
  }]
}'

发送附件示例

import base64

# 读取文件并编码
with open("report.pdf", "rb") as f:
    data_base64 = base64.b64encode(f.read()).decode()

# 使用 data_base64 作为 attachments[].data_base64

Usage Guidance
This skill appears to implement mail send/receive via a helper (mail-mcp), but pay attention before installing: - Sensitive credentials: You will need to provide an email account and password (or app password). The SKILL.md suggests placing these in ~/.mcporter/mcporter.json (likely plaintext). Prefer creating an app-specific or least-privileged account and avoid reusing primary credentials. Check file permissions (chmod 600) and consider using a credentials manager or environment variables scoped to a short-lived session. - Install source: The included install.sh runs pip install directly from a GitHub repository. Inspect the upstream repository (https://github.com/AdJIa/mail-mcp-server) before running the installer. Run installs inside a virtualenv or container rather than system Python, and avoid --break-system-packages unless you understand the effect. - Missing declarations: The registry metadata does not declare required env vars/primary credential. Ask the publisher to declare the required credentials explicitly and to document how credentials are stored and protected. - What to do now: If you want to proceed, review the GitHub repo code, run the installer in an isolated environment, and use an app-specific mailbox/credentials. If you cannot audit the upstream code, treat this skill as higher risk and avoid supplying real account credentials.
Capability Analysis
Type: OpenClaw Skill Name: mail-skill Version: 0.1.0 The skill automates the installation of an external tool directly from a GitHub repository (AdJIa/mail-mcp-server) using `pip install` in `install.sh`, which introduces a supply chain risk by executing unverified remote code. Furthermore, `SKILL.md` instructs the agent to guide users into storing plaintext IMAP/SMTP credentials in a local configuration file (~/.mcporter/mcporter.json). While these actions are functionally consistent with the stated goal of email management, the combination of unverified remote execution and insecure credential handling presents a significant security risk.
Capability Assessment
Purpose & Capability
The skill's stated purpose (IMAP/SMTP mail management) matches the instructions and helper tool (mail-mcp). However the registry metadata lists no required environment variables or primary credential even though the SKILL.md clearly requires IMAP/SMTP credentials (EMAIL_USER, EMAIL_PASSWORD, IMAP_HOST, SMTP_HOST, etc.). That omission is inconsistent.
Instruction Scope
SKILL.md stays within the mail-management scope (install mail-mcp, configure mcporter, call mail-mcp commands). It does instruct the user to add sensitive credentials into ~/.mcporter/mcporter.json or environment variables, but it does not instruct reading unrelated system files or exfiltrating data. Still, instructions lack guidance about secure storage/permissions for those credentials.
Install Mechanism
There is no declared install spec in the registry, but an included install.sh runs pip install git+https://github.com/AdJIa/mail-mcp-server.git (with --break-system-packages). Installing directly from a GitHub repo is common but has higher risk than installing a vetted package; --break-system-packages can alter system Python state. The install script writes nothing else and otherwise is simple, but the absence of a formal install entry in metadata is inconsistent.
Credentials
The skill requires highly sensitive credentials (email account and password or app-specific password) to function, but the registry metadata does not declare any required env vars or a primary credential. The instructions suggest storing passwords in ~/.mcporter/mcporter.json (likely plaintext) without recommending secure handling or minimal-scoped credentials. This is disproportionate to how the skill is documented in the registry.
Persistence & Privilege
The skill is not always:true and does not request elevated or persistent platform privileges. It does not modify other skills' configs. Autonomous invocation is allowed (default) but is not combined with other strong red flags here.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install mail-skill
  3. After installation, invoke the skill by name or use /mail-skill
  4. Provide required inputs per the skill's parameter spec and get structured output
