Set up

Add Microsoft 365 User Profile to Hermes in four steps

Admins approve the server once. Everyone in Hermes then gets it through the same governed connection.

  1. 1

    Approve Microsoft 365 User Profile in Runlayer

    Add Microsoft 365 User Profile from the catalog and choose who can use it and which of its tools are allowed.

  2. 2

    Connect Hermes to Runlayer

    Users add the Runlayer Plugin to Hermes by following Runlayer’s setup guide. Hermes reaches Microsoft 365 User Profile’s 5 tools through the Runlayer Plugin’s search and execute tools instead of listing each one.

    Hermes setup guide
  3. 3

    Sign in to Microsoft 365 User Profile

    Each user signs in to Microsoft 365 User Profile with OAuth. Runlayer keeps the tokens out of the client’s configuration.

  4. 4

    Use Microsoft 365 User Profile from Hermes

    Microsoft 365 User Profile’s approved tools appear in Hermes. Every call is checked against policy and recorded.

Tools

5 Microsoft 365 User Profile tools in Hermes

Runlayer policy decides which of these Hermes users can call.

  • Get direct reports details

    Retrieve a user's team, or direct reports (people who report to them in the organizational hierarchy).

  • Get manager details

    Get a user's manager information - name, email, job title, etc. ⚠️ TOOL DEPENDENCY RULE: If the user request references a person (name, alias, email fragment, etc.), you MUST call the GetUserDetails…

  • Get multiple users details

    Search for multiple users in the directory by name, job title, office location, or other properties.

  • Get my details

    Retrieve profile details for the currently signed-in user ("me, my").

  • Get User details

    Retrieve a user's profile by UPN or Entra object ID (GUID).

Control

What Runlayer can see and stop in Hermes

Some controls apply to every client at the gateway. Others depend on what Hermes exposes to Runlayer.

  • Gateway policy (available)

    Every Microsoft 365 User Profile call from Hermes passes through Runlayer, where your policies can allow, alert, mask, or block it.

  • Audit trail (available)

    Each call is recorded with the user, Hermes as the client, the tool, and the policy and scanner decisions.

  • Client hooks (available)

    Capture supported prompts, reasoning, local and MCP tool calls, responses, and scanner decisions in real time.

  • Stop a call before it runs (available)

    Runlayer can deny a tool call before Hermes runs it.

  • Block output after it runs (available)

    Runlayer can block a tool’s output in Hermes and show a message in its place.

  • Redact output in place (not available)

    Hermes cannot take masked output, so Runlayer can block a tool’s output but not mask it. The gateway still applies policy to the call.

In Hermes

  • Hermes can replace blocked tool output with a message, but its after-call event is for monitoring only.
