Local MCP Server Connects Claude to Mac Apps Without Cloud or Tokens

What Local MCP Does

Local MCP is a native macOS MCP server that connects Claude Desktop (along with Cursor, Windsurf, and VS Code) to local Mac applications. The tool provides direct access to several productivity applications without requiring cloud processing or API tokens.

Core Features

• Read, search, send, and reply to emails from Mail.app (supports Gmail, Outlook, iCloud, Exchange)
• Create, list, and delete calendar events across all accounts
• Read Microsoft Teams chats and channels without Graph API tokens
• Full OneDrive file management including read, write, search, and move operations
• Support for Word, Excel, PowerPoint, and PDF files

Key Differentiators

• Privacy-first approach: All data remains on your Mac with zero cloud processing
• Zero configuration required: Install and restart Claude Desktop
• Teams integration reads from local IndexedDB, eliminating OAuth and Microsoft API requirements
• Includes 38 MCP tools with safety previews (emails show preview before sending, requiring user confirmation)

Installation

Install via npm:

npm install -g local-mcp

Or add to your Claude Desktop configuration:

{"mcpServers":{"local-mcp":{"command":"npx","args":["-y","local-mcp@latest"]}}}

Availability

The tool offers a 14-day free trial with no credit card required. The developer is actively seeking feedback from users.
