Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00166 | $0.03897 |
| Opus 5 | $0.00083 | $0.01948 |
| Sonnet 5 | $0.00033 | $0.00779 |
| Haiku 4.5 | $0.00017 | $0.00390 |
Grade C, and why
obsidian-helper scanned grade C with 2 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 12d 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

mcp.json carries server URLs and auth tokens; reading it lets a mod discover and abuse other integrations.

Obsidian Helper - 智能笔记助手
这是一个与 Obsidian MCP 深度整合的智能助手,提供三大核心功能来提升你的笔记效率。
⚡ 首次使用必读:自动检测与配置引导
执行任何功能前,Claude 必须先执行 STEP 0
STEP 0: MCP 连接检测(每次会话首次使用时执行)
├─ 尝试调用 obsidian_list_files_in_vault()
├─ 如果成功 → 继续执行用户请求的功能
└─ 如果失败 → 进入【配置引导流程】
配置引导流程(全中文提示)
当 MCP 连接失败时,Claude 必须向用户显示以下引导信息:
检测到 Obsidian MCP 未连接,我来帮你配置!
📋 配置步骤
第一步:安装 Obsidian 插件
- 打开 Obsidian → 设置 → 第三方插件
- 关闭「安全模式」
- 点击「浏览」,搜索 Local REST API
- 安装并启用该插件
第二步:获取 API Key
- 在 Obsidian 设置中找到 Local REST API 插件设置
- 点击「Copy API Key」复制你的 API Key
- 记下端口号(默认是
27124)
第三步:配置 Claude Code MCP
在终端运行以下命令,将 你的API_KEY 替换为刚才复制的 Key:
# 创建 MCP 配置目录(如果不存在)
mkdir -p ~/.claude
# 添加 Obsidian MCP 配置
cat >> ~/.claude/mcp.json << 'EOF'
{
"mcpServers": {
"mcp-obsidian": {
"command": "npx",
"args": ["-y", "mcp-obsidian"],
"env": {
"OBSIDIAN_API_KEY": "你的API_KEY",
"OBSIDIAN_HOST": "https://127.0.0.1:27124"
}
}
}
}
EOF
或者手动编辑 ~/.claude/mcp.json:
{
"mcpServers": {
"mcp-obsidian": {
"command": "npx",
"args": ["-y", "mcp-obsidian"],
"env": {
"OBSIDIAN_API_KEY": "你的API_KEY",
"OBSIDIAN_HOST": "https://127.0.0.1:27124"
}
}
}
}
第四步:重启 Claude Code
# 完全退出 Claude Code,然后重新启动
claude
第五步:验证连接
重启后,再次输入你想要的命令(如 /daily),我会自动验证连接是否成功。
❓ 常见问题
| 问题 | 解决方案 |
|---|---|
| 插件找不到 | 确保 Obsidian 版本 ≥ 1.0.0 |
| 连接被拒绝 | 检查 Obsidian 是否正在运行 |
| API Key 无效 | 重新在插件设置中复制 Key |
| 端口冲突 | 在插件设置中修改端口,并更新 mcp.json |
需要帮助? 告诉我你遇到的具体错误信息,我来帮你解决。
连接成功后的提示
当 MCP 连接成功时,Claude 应该简短确认:
✅ Obsidian 已连接!检测到你的知识库,现在开始执行 [功能名称]...
🎯 核心功能概览
| 命令 | 功能 | 使用场景 |
|---|---|---|
/daily |
智能日记助手 | 每日开始时,快速启动一天 |
/capture <主题> |
知识捕获 | 随时记录想法、笔记 |
/review [period] |

What ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 12d ago First seen · 562 lines · 166 tokens per session scan C f1452300a2b2
obsidian-helper is a skill published in the GitHub repository ZhanlinCui/Agent-Skills-Hunter (186 stars, last pushed 6mo ago), licensed MIT. It adds 166 tokens to every session and 3,897 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it C with 2 findings (reads agent configuration directories, reads mcp configuration). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
