What it does

Bridges Microsoft Graph: mail, calendar, files, and the directory. Requires an Azure app registration and admin consent, which is the real work — the server itself is the easy part. In most organisations the bottleneck is the consent, not the code.

Install

Terminal

npx -y @softeria/ms-365-mcp-server

Client configuration

Paste this into your MCP client config (Claude Desktop, Cursor, or any client that reads mcpServers), then restart the client.

mcp.json

{
  "mcpServers": {
    "microsoft-365": {
      "command": "npx",
      "args": [
        "-y",
        "@softeria/ms-365-mcp-server"
      ]
    }
  }
}

Use it for

Reading mail and calendar inside a Microsoft tenant

Skip it if

Consumer Outlook accounts or tenants that block third-party apps

When to use it

Reach for this when the task needs microsoft365 inside the agent loop. Skip it if a plain shell command or a one-off script is enough — every server you add costs context and adds a failure mode.

Other TypeScript servers

Filesystem — Gives an agent scoped read, write, and search access to directories you explicitly allow
Memory — A persistent knowledge graph stored in a local JSON file, exposed through entities, relations, and observations
Sequential Thinking — Gives the model a scratchpad for structured, revisable reasoning: numbered thoughts that can branch, revise, and conclude
