Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "outlook": {
      "command": "npx",
      "args": [

      ]
    }
  }
}

Run this in your terminal

claude mcp add outlook -- npx -y olkcli mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "outlook": {
      "command": "npx",
      "args": [
        "-y",
        "olkcli",
        "mcp"

Common questions

Is Outlook safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.16.1) reached the registry 26 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

olk — Microsoft Outlook in Your Terminal

olk is a scriptable CLI and MCP server for Outlook mail, calendars, contacts, tasks, and OneDrive through Microsoft Graph. It works with personal Outlook.com accounts and enterprise Microsoft 365 accounts.

Install

brew install rlrghb/tap/olk

or

go install github.com/rlrghb/olkcli/cmd/olk@latest

The npm package is olkcli; the installed command is olk:

npm install -g olkcli

See macOS notes if macOS asks for Keychain access after an upgrade.

Quick start

olk auth login

olk auth status olk mail list --json --results-only --select id,subject,from olk mail search 'from:person@example.com subject:urgent' olk calendar view --days 7 olk contacts search "Alex" olk todo lists list olk drive ls

For work/school accounts and enterprise-only features:

olk auth login --enterprise

Common commands

Need	Command
Check the signed-in account	`olk auth status` or `olk whoami`
Find message IDs and subjects	`olk mail list --json --results-only --select id,subject,from`
Search mail	`olk mail search "from:person@example.com subject:urgent"`
View the next week	`olk calendar view --days 7`
Search contacts	`olk contacts search "Alex"`
List task lists	`olk todo lists list`
Browse OneDrive	`olk drive ls`
Send mail	`olk mail send --to person@example.com --subject "Hi" --body "Hello"`
Draft a reply-all with an extra Cc	`olk mail reply --reply-all --draft --body "$(cat reply.txt)" --cc person@example.com`
Draft HTML with an inline image	`olk mail drafts create --to person@example.com --subject "Steps" --html --body ' ' --inline steps=steps.png`
Synchronize changes	`olk changes --json`
Use JSON for scripts	`olk mail list --json --results-only`
Use as an MCP server	`olk mcp`

See the command reference for all commands and flags.

Inline images in HTML drafts

Use a cid: URL in the HTML and supply the matching image with repeatable --inline CID=PATH flags. This works for new drafts and true threaded reply or reply-all drafts:

olk mail reply <ID> --draft --html \

--body ' See both images: ' \ --inline logo=logo.png --inline steps=steps.png

olk mail drafts create --to person@example.com --subject "Instructions" --html \ --body ' Follow these steps: ' \ --inline steps=steps.png

Each CID must be unique and referenced by the HTML. Files must be images and each must be under 3 MB, the Microsoft Graph simple-attachment limit. Draft commands do not send mail; immediate sends and forwards do not accept --inline.

Output and scripting

Results are written to stdout; diagnostics and prompts go to stderr.

olk mail list --json --results-only | jq '.[].subject'

olk contacts list --plain

Output modes are JSON (--json), TSV (--plain), and aligned tables by default. Use --concise to omit large bodies/previews and --select to limit fields where supported. See scripting and sync.

Safety defaults

Use --no-write --no-send --no-input for unattended read-only runs.
MCP exposes curated tools and requires explicit opt-in for mutations.
External mail, calendar, contact, and file text can be wrapped with --wrap-untrusted for agent-safe consumption.
Refresh tokens are stored in the OS keychain; access tokens are kept in memory only.

Read the security and privacy guide before connecting an agent or sharing logs.
