Reliability & compatibility
Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Outlook Local MCP Server
A single-binary MCP server that connects Claude Desktop and Claude Code to Microsoft Outlook via the Microsoft Graph API. Manage your calendar, read email, and compose drafts without leaving your AI assistant.
Install
Go binary (recommended):
go install github.com/desek/outlook-local-mcp/cmd/outlook-local-mcp@latest
Claude Desktop extension (no terminal required):
Download the .mcpb file from the latest release and open it in Claude Desktop via Settings > Extensions > Install from file.
Tool invocation shape
All operations use four aggregate domain tools dispatched by an operation verb:
{tool: "calendar", args: {operation: "list_events", date: "today"}}
{tool: "mail", args: {operation: "list_folders"}}
{tool: "account", args: {operation: "list"}}
{tool: "system", args: {operation: "status"}}
Call any domain with operation: "help" to list its verbs and parameters.
