Mcp Office — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited Mcp Office (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

Local-first, governed MCP servers for Microsoft Office — built for developers who want to treat Office files the way they treat code.
MCP Office is a suite of Model Context Protocol servers that expose Microsoft Office capabilities as governed, deterministic tool calls. Each server runs locally on Windows, connects to your MCP client (Claude Desktop, VS Code Copilot, or any MCP-compatible client), and gives you structured control over Office files — without an in-app AI assistant.
This is not a Copilot replacement. It is a developer-first execution layer for Office automation.
| Package | What it does | Install | Tools |
|---|---|---|---|
excelmcp | Read, write, style, validate, and export Excel workbooks | pip install mcp-office | 65 |
pptmcp | Build, edit, review, and export PowerPoint presentations. Output Contract framework for machine-verifiable slide specs | pip install mcp-office | 51 |
wordmcp | Template assembly, tracked-changes support, and structural QA for Word documents | pip install mcp-office | 50 |
| Package | Status |
|---|---|
mailmcp | Integrated into the current source distribution; Windows Outlook UAT and published-artifact verification pending |
MailMCP is now included in the repository's single mcp-office source distribution, but the currently published PyPI artifact does not yet claim MailMCP availability. See mailmcp/README.md for source validation while Windows Outlook UAT and release verification remain open.
New packages are added as they complete their proof cycle. See ROADMAP.md.

pip install mcp-officeOr clone and install the consolidated suite from source (including MailMCP and Windows COM support):

cd mcp-office

python -m pip install -e ".[com]"Open %APPDATA%\Claude\claude_desktop_config.json (create it if it doesn't exist) and add the servers you installed:

}Replace C:\\path\\to\\your\\files with the directory where your Office files live. Restart Claude Desktop after saving.
In Claude Desktop, send:
Call capabilities() on excel-excelmcp
Call capabilities() on powerpoint-pptmcp
Call capabilities() on word-wordmcpEach should return a tool list (65 for Excel, 51 for PowerPoint, 50 for Word). If a server is missing, check that python resolves to the venv where you installed mcp-office.

| Requirement | Notes |
|---|---|
| Windows 10 or 11 | COM automation requires Windows |
| Python 3.11+ | python --version to confirm |
| Microsoft Office | Required for COM-dependent tools (styling, PDF export, tracked-changes). Read-only docx/xlsx/pptx tools work without Office. |
| Classic Outlook desktop | Required for MailMCP. MailMCP remains release-pending until Windows Outlook UAT and published-artifact verification pass. |
| MCP client | Claude Desktop or VS Code with Copilot |
