Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

excel scanned grade A with 0 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 7d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

快速调用

方式一:Skill 接入(首推)

安装(二选一):

# 方式 A:OMP harness 用户(自动注册 skill)
# skill 文件部署到 ~/.omp/agent/skills/excel/,harness 自动发现

# 方式 B:手动安装
git clone https://github.com/TangentDomain/excel-mcp-server.git
cp -r excel-mcp-server/.omp/skills/excel ~/.omp/agent/skills/excel

使用

# 首次运行自动安装依赖(uv venv + pip install 从 GitHub)
python ~/.omp/agent/skills/excel/bin/excel-cli.py query --file data.xlsx --sql "SELECT * FROM Sheet1"

# Windows venv 安装后可直接用 exe(跳过自举,更快)
~/.omp/agent/skills/excel/.venv/Scripts/excel-cli.exe <command> [options]

# 检查更新
excel-cli self-update --check
excel-cli self-update          # 更新到最新版

Skill 入口:~/.omp/agent/skills/excel/bin/excel-cli.py,首次运行自动创建 venv + 从 GitHub 安装,后续通过 self-update 更新。

方式二:源码直接调用(开发环境)

本项目即为 excel-mcp-server 源码,可以用 uv run 直接调用:

uv run python -m excel_mcp_server_fastmcp.cli <command> [options]

输出格式(所有命令统一):JSON {success: bool, data: Any, message: str, meta: dict}

所有命令共用参数--file <路径> 是每个命令的必填参数(除 self-update)。路径用绝对路径。

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.
