What it does

Microsoft Graph API is an agent skill from aiskillstore/marketplace. This skill should be used when the user asks to "read my emails", "send an email", "compose email", "check my calendar", "get calendar events", "create a meeting", "schedule an event", "add calendar event", "search emails", "list mail folders", "show unread messages", "what meetings do I have", "fetch emails from Microsoft", "access Outlook", or mentions Microsoft Graph, Office 365 email, or Outlook calendar integration.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 14 other files, including scripts and reference files (for example `references/graph-api.md`, `scripts/auth.ts` and `scripts/calendar.ts`).

It sits in Backend & APIs, covering Cloud office suites. It works with Microsoft 365 and Microsoft Outlook. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.

When your agent uses it

  • Asks to read my emails
  • Check my calendar
  • Get calendar events
  • Create a meeting

Example prompts

  • “read my emails”
  • “send an email”
  • “compose email”
  • “/microsoft-graph-api”

Requirements

  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit 4ac52da. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 9 files in scripts/ (TypeScript), which the agent can run.

    Shell commands in SKILL.md call:

    • bun

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • microsoft.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Microsoft Graph API loads about 1.5k tokens when it runs, and up to ~2.9k if it reads all its reference files. Until then it costs about 111 tokens; SKILL.md has 250 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~111
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 250 words (~1,505 tokens).

“Access Microsoft 365 emails and calendar through TypeScript scripts executed via Bun.”

Does Microsoft Graph API access the network?

SKILL.md names 1 domain. In commands or code: microsoft.com; the agent is likely to contact it when it follows the instructions. This is read from the text; nothing was executed.

Is Microsoft Graph API safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
