What this skill does

# Microsoft Graph Agent Skill

Search, look up, and call any of the 27,700+ Microsoft Graph APIs — all locally, no network calls needed. Use the three search commands to find the right endpoint, check permissions and parameters, then optionally execute calls directly or hand off to a Graph MCP server.

## What's Included

The Microsoft Graph API has **27,700+ endpoints** updated weekly — well past LLM training cutoffs. This skill bundles the complete API surface as local indexes that you search instantly with no network calls.

| Index | Count | What it contains |
|---|---|---|
| OpenAPI endpoints | 27,700+ | Path, method, summary, description, permission scopes |
| Endpoint docs | 6,200+ | Permissions (delegated/app), query parameters, required headers, default vs `$select`-only properties |
| Resource schemas | 4,200+ | All properties with types, supported `$filter` operators, default/select-only flags |
| Community samples | Growing | Hand-verified queries mapping natural-language tasks to exact API calls |

## How to Run

The `msgraph` CLI is bundled with this skill. Run all commands through the launcher script in this skill's directory:

- **macOS / Linux**: `bash <path-to-this-skill>/scripts/run.sh <command> [args...]`
- **Windows**: `powershell <path-to-this-skill>/scripts/run.ps1 <command> [args...]`

For example, to search for mail-related APIs on macOS:

```
bash /home/user/.opencode/skills/msgraph/scripts/run.sh openapi-search --query "send mail"
```

In all examples below, `msgraph` is shorthand for the full launcher invocation.

## Finding the Right API

This is the primary purpose of the skill. Follow this progressive lookup strategy — each level adds detail:

1. **Your own knowledge** — try first for well-known endpoints (`/me`, `/users`, `/groups`).
2. **`sample-search`** — curated, hand-verified samples. Highest quality. Use for common tasks and multi-step workflows.
3. **`api-docs-search`** — per-endpoint permissions, supported query parameters, required headers, default vs `$select`-only properties, and resource property details with filter operators.
4. **`openapi-search`** — full catalog of 27,700 Graph APIs. Use when you cannot find the endpoint any other way.
5. **Reference files** — concept docs on query parameters, advanced queries, paging, batching, throttling, errors, and best practices. Read only when you need specific guidance.

This order is guidance — adapt based on the task. For example, jump straight to `api-docs-search` if you already know the endpoint but need its permissions.

### sample-search

Search curated community samples that map natural-language tasks to exact Microsoft Graph API queries:

```
msgraph sample-search --query "conditional access policies"
msgraph sample-search --product entra
msgraph sample-search --query "managed devices" --product intune
```

| Flag | Description |
|---|---|
| `--query` | Free-text search (searches intent and query fields) |
| `--product` | Filter by product: `entra`, `intune`, `exchange`, `teams`, `sharepoint`, `security`, `general` |
| `--limit` | Max results (default 10) |

At least one of `--query` or `--product` is required. Results include multi-step workflows.

### api-docs-search

Look up detailed documentation for a specific endpoint or resource type:

```
msgraph api-docs-search --endpoint /users --method GET
msgraph api-docs-search --resource user
msgraph api-docs-search --query "ConsistencyLevel"
```

| Flag | Description |
|---|---|
| `--endpoint` | Search by endpoint path (e.g. `/users`, `/me/messages`) |
| `--resource` | Search by resource type name (e.g. `user`, `group`, `message`) |
| `--method` | Filter by HTTP method: `GET`, `POST`, `PUT`, `PATCH` |
| `--query` | Free-text search across all fields |
| `--limit` | Max results (default 10) |

At least one of `--endpoint`, `--resource`, or `--query` is required.

**Endpoint results** include: required permissions (delegated work/school, delegated personal, application), supported OData query parameters, required headers, default properties, and endpoint-specific notes.

**Resource results** include: all properties with types, supported `$filter` operators (eq, ne, startsWith, etc.), and whether each property is returned by default or requires `$select`.

### openapi-search

Search the full OpenAPI catalog of 27,700 Microsoft Graph APIs:

```
msgraph openapi-search --query "send mail"
msgraph openapi-search --resource messages --method GET
```

| Flag | Description |
|---|---|
| `--query` | Free-text search (searches path, summary, description) |
| `--resource` | Filter by resource name (e.g. `users`, `groups`, `messages`) |
| `--method` | Filter by HTTP method |
| `--limit` | Max results (default 20) |

At least one of `--query`, `--resource`, or `--method` is required.

## Using with MCP Servers

If the agent has access to a Microsoft Graph MCP server (such as [lokka.dev](https://lokka.dev) or any other Microsoft Graph MCP server), use the search tools above to find the right endpoint, permissions, and request syntax, then use the information with the MCP server for execution.

In this mode, **no authentication through this skill is needed**. The skill acts purely as a knowledge layer — the MCP server handles authentication and API execution.

## Direct Microsoft Graph API Execution

When no Graph MCP server is available, this skill can authenticate to Microsoft 365 and execute Microsoft Graph API calls directly.

### Authentication

The tool supports **delegated (user)** and **app-only (application)** authentication, auto-detected from environment variables.

**Quick start:**

```
msgraph auth status          # check if signed in
msgraph auth signin          # sign in (opens browser) - recommended
msgraph auth signin --device-code  # sign in via device code (headless)
msgraph auth signout         # clear the session
```

- **Delegated auth** (default): Interactive browser sign-in, with device code fallback for headless environments. Supports incremental consent — on 403, the tool re-authenticates with required scopes and retries automatically.
- **App-only auth**: Auto-detected when `MSGRAPH_CLIENT_SECRET`, `MSGRAPH_CLIENT_CERTIFICATE_PATH`, `MSGRAPH_FEDERATED_TOKEN_FILE`, or `MSGRAPH_AUTH_METHOD=managed-identity` is set. Requires `MSGRAPH_TENANT_ID`.

For detailed authentication configuration including certificates, managed identity, workload identity federation, and all environment variables, see [references/docs/authentication.md](references/docs/authentication.md).

### Making Graph API Calls

**IMPORTANT**: Run `msgraph auth status` before the first `graph-call` in a session to verify authentication.

```
msgraph graph-call <METHOD> <URL> [flags]
```

#### Read Operations

```
msgraph graph-call GET /me
msgraph graph-call GET /users --select "displayName,mail" --top 10
msgraph graph-call GET /me/messages --filter "isRead eq false" --top 5 --select "subject,from,receivedDateTime"
msgraph graph-call GET /users --filter "startsWith(displayName,'John')"
```

#### Write Operations

**IMPORTANT**: YOU MUST ask the user for confirmation before any write operation. Write operations require the `--allow-writes` flag.

```
msgraph graph-call POST /me/sendMail --body '{"message":{"subject":"Hello","body":{"content":"Hi"},"toRecipients":[{"emailAddress":{"address":"[email protected]"}}]}}' --allow-writes
msgraph graph-call PATCH /me --body '{"jobTitle":"Engineer"}' --allow-writes
```

**DELETE is always blocked** regardless of flags.

#### graph-call Flags

| Flag | Description | Example |
|---|---|---|
| `--select` | OData $select | `--select "displayName,mail"` |
| `--filter` | OData $filter | `--filter "isRead eq false"` |
| `--top` | OData $top (limit results) | `--top 10` |
| `--expand` | OData $expand | `--expand "members"` |
| `--orderby` | OData $orderby | `--orderby "displayName desc"` |
| `--api-version` | `v1.0` or `beta` (default: beta) | `--api-version v1.0` |
| `--scopes` | Request additional permi
