## Introduction

Hermes is a 24/7 autonomous agent that lives on your computer or server — it remembers what it learns and evolves as your usage grows.
This guide explains the easiest and most robust way to connect your Microsoft Viva Engage account to Hermes. You can do this through either Composio Connect CLI or Composio Connect MCP. For personal use we recommend the CLI, but you won't go wrong with MCP either.

- Search and load tools from relevant toolkits on-demand, reducing context usage.
- Chain multiple tools to accomplish complex workflows via a remote workbench, without excessive back-and-forth with the LLM.
- Manage app authentication end-to-end with zero manual overhead.

## Connect Microsoft Viva Engage to Hermes

1. Install the Composio CLI
Run the install script directly, or paste https://composio.dev/hermes into your Hermes chat box to have it installed for you.

```bash
curl -fsSL https://composio.dev/install | bash
```

## What is the Microsoft Viva Engage MCP server, and what's possible with it?

The Microsoft Viva Engage MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Microsoft Viva Engage account. It provides structured and secure access to Viva Engage communities, members, owners, and engagement roles, so your agent can create and update communities, manage members and owners, discover engagement roles, and assign or remove role memberships on your behalf.
- Community management: Have your agent create communities, update their names, descriptions, or privacy settings, list available communities, and delete communities when needed.
- Member administration: Let the agent add individual members or groups of members to a community, list current members, and remove members without deleting their user accounts.
- Owner management: Direct your agent to add community owners, list current owners, or remove a user's community admin status.
- Engagement role discovery: Instruct your agent to list the predefined Viva Engage administrative and corporate communication roles, including the roles assigned to you or another user.
- Role assignments: Have your agent assign or remove a predefined Viva Engage engagement role for a user.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `MICROSOFT_VIVA_ENGAGE_ADD_COMMUNITY_MEMBER` | Add Community Member | Add one Microsoft Entra user to a Viva Engage community by adding the user to its associated Microsoft 365 group. Requires group_id from community.groupId, not the Viva Engage community ID. |
| `MICROSOFT_VIVA_ENGAGE_ADD_COMMUNITY_MEMBERS_BULK` | Add Community Members in Bulk | Atomically add up to 20 users to a Viva Engage community's associated Microsoft 365 group. If any user reference is invalid, no users are added. |
| `MICROSOFT_VIVA_ENGAGE_ADD_COMMUNITY_OWNER` | Add Community Owner | Make one Microsoft Entra user a Viva Engage community admin by adding the user as an owner of the community's associated Microsoft 365 group. This grants administrative privileges: confirm the target user and group before calling. Add the owner as a member separately if member capabilities are also required. Requires group_id from community.groupId, not the Viva Engage community ID. |
| `MICROSOFT_VIVA_ENGAGE_ASSIGN_ENGAGEMENT_ROLE_MEMBER` | Assign Engagement Role Member | Assign one predefined Viva Engage administrative or corporate communication role to a Microsoft Entra user. This changes the user's privileges; confirm both the role and target user before calling. Retain the returned member ID for safe removal; Graph currently uses the target user ID as that member ID when this route returns 204. |
| `MICROSOFT_VIVA_ENGAGE_CREATE_COMMUNITY` | Create Community | Start asynchronous creation of a Viva Engage community. This provisions Microsoft 365 tenant resources and returns an operation reference; poll the operation separately before treating the community as created. |
| `MICROSOFT_VIVA_ENGAGE_DELETE_COMMUNITY` | Delete Community | Permanently delete a Viva Engage community and all associated Microsoft 365 content, including its connected group, OneNote notebook, and Planner plans. This destructive action cannot be undone. |
| `MICROSOFT_VIVA_ENGAGE_GET_COMMUNITY` | Get Community | Get one Viva Engage community by community ID, including its distinct associated Microsoft 365 group ID. |
| `MICROSOFT_VIVA_ENGAGE_GET_ENGAGEMENT_ASYNC_OPERATION` | Get Engagement Async Operation | Get the status and resulting resource reference for a Viva Engage asynchronous operation such as community creation. Make separate calls more than 30 seconds apart while polling. |
| `MICROSOFT_VIVA_ENGAGE_LIST_COMMUNITIES` | List Communities | List Viva Engage communities in the tenant, one Microsoft Graph page at a time, including each community ID and associated Microsoft 365 group ID. |
| `MICROSOFT_VIVA_ENGAGE_LIST_COMMUNITY_MEMBERS` | List Community Members | List direct members of a Viva Engage community's associated Microsoft 365 group, one Microsoft Graph OData page at a time. Requires group_id from community.groupId, not the Viva Engage community ID. Hidden members are visible only when the connection also has Member.Read.Hidden. |
| `MICROSOFT_VIVA_ENGAGE_LIST_COMMUNITY_OWNERS` | List Community Owners | List owners of a Viva Engage community's associated Microsoft 365 group, who are community admins, one Microsoft Graph OData page at a time. Requires group_id from community.groupId, not the Viva Engage community ID. |
| `MICROSOFT_VIVA_ENGAGE_LIST_ENGAGEMENT_ROLE_MEMBERS` | List Viva Engage Role Members | List users assigned to one predefined Viva Engage role and return the selected assignment properties. Include id for later removal and userId for identity correlation. Requires a role_id from List Viva Engage Roles and a native-mode Viva Engage network; legacy and external networks are unsupported. |
| `MICROSOFT_VIVA_ENGAGE_LIST_ENGAGEMENT_ROLES` | List Viva Engage Roles | List the predefined administrative and corporate communication roles that can be assigned in Viva Engage, one Microsoft Graph page at a time. Custom roles cannot be created, and this API supports only native-mode Viva Engage networks with a work or school account. |
| `MICROSOFT_VIVA_ENGAGE_LIST_MY_ASSIGNED_ENGAGEMENT_ROLES` | List My Assigned Viva Engage Roles | List Viva Engage roles assigned to the signed-in work or school user, one Microsoft Graph page at a time. |
| `MICROSOFT_VIVA_ENGAGE_LIST_USER_ASSIGNED_ENGAGEMENT_ROLES` | List User Assigned Viva Engage Roles | List Viva Engage roles assigned to a specified Microsoft Entra user, one Microsoft Graph page at a time. |
| `MICROSOFT_VIVA_ENGAGE_REMOVE_COMMUNITY_MEMBER` | Remove Community Member | Remove one user from a Viva Engage community's associated Microsoft 365 group, revoking community membership without deleting the user object. Dynamic-group memberships cannot be changed with this action. The request always retains the safety-critical /$ref suffix. |
| `MICROSOFT_VIVA_ENGAGE_REMOVE_COMMUNITY_OWNER` | Remove Community Owner | Remove a user's community admin status by removing the user as an owner of the Viva Engage community's associated Microsoft 365 group. This is destructive to admin access: verify another user owner remains because Microsoft Graph does not allow removal of the last user owner. The request always retains the safety-critical /$ref suffix. |
| `MICROSOFT_VIVA_ENGAGE_REMOVE_ENGAGEMENT_ROLE_MEMBER` | Remove Engagement Role Member | Revoke one user's Viva Engage role assignment. This can remove administrative or corporate communication privileges: confirm the role and assignment before calling. Use the role_member_id returned by listing or assigning role members; Graph currently uses the target user ID as this member ID on assignment. |
| `MICROSOFT_VIVA_ENGAGE_UPDATE_COMMUNITY` | Update Community | Update a Viva Engage community's name, description, or privacy by community ID. Provide at least one field; omitted fields remain unchanged. |

## Conclusion

### Way Forward
With Microsoft Viva Engage connected, Hermes can now act on your behalf whenever it detects a relevant task or you ask it to.
From here, you can extend Hermes further:
- Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup. Each new integration compounds what Hermes can do for you.
- Build workflows across tools: Once multiple apps are connected, Hermes can chain actions together — turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft.
- Let it learn your patterns: The more you use Hermes, the better it gets at anticipating how you'd handle recurring tasks. Give it feedback on drafts and decisions, and it will adapt.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Microsoft Viva Engage MCP?

With a standalone Microsoft Viva Engage MCP server, the agents and LLMs can only access a fixed set of Microsoft Viva Engage tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Microsoft Viva Engage and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Hermes?

Yes, you can. Hermes fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Microsoft Viva Engage tools.

### Can I manage the permissions and scopes for Microsoft Viva Engage while using Tool Router?

Yes, absolutely. You can configure which Microsoft Viva Engage scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Microsoft Viva Engage data and credentials are handled as safely as possible.
