Entrapulse Polyarchy MCP server

EntraPulse Polyarchy

An interactive Microsoft Entra ID identity relationship visualization, served as an MCP App.

In 2003 Microsoft demoed PolyArchy Server — a web visual over identity data showing intersecting relationship hierarchies, where clicking a datapoint flipped the whole view to that context. It never shipped. This is it, finally real: a live D3 force-graph over your Entra ID tenant that renders inside your MCP client (Claude Desktop, VS Code Copilot, M365 Copilot, ChatGPT, Cursor, Goose, Postman — anything that supports the MCP Apps extension).

Ask your assistant "show me the identity polyarchy around Rebecca" and explore:

common defaults (department, office, city…) or type ahead into the full Graph attribute catalog, including nested paths like onPremisesExtensionAttributes/extensionAttribute9

• Org — manager chains and direct reports
• Groups — memberships, and group fan-out to members
• Attributes — pivot hubs linking everyone who shares a value: pick from the

• Access — directory roles and app assignments

Prefer data over pictures? polyarchy-report returns the same relationships as structured JSON — manager chain, group memberships with type and assigned/dynamic, roles, app assignments — for the assistant to reason over, no UI required.

whole context to it: hop distances re-anchor, the view glides to center, and its relationships load. The original PolyArchy interaction.

• Click a node to open its profile panel (photo, attributes, manager chain link).
• Double-click any node — or use the panel's Set as focus button — to flip the

everything fetched this session stays cached, so re-exploring the same people, groups or cohorts rebuilds instantly with zero extra Graph calls. The status bar shows when a neighbourhood was served from cache.

• Reset (toolbar) clears the canvas for a fresh lineage without losing anything:

card. The automatic fullscreen claim happens only when a polyarchy opens, so this is the way back to full canvas after minimising in the host. Hidden on hosts without fullscreen support.

• Expand / Minimise (toolbar) toggles the app between fullscreen and its inline

• Legend checkboxes filter relationship kinds and object types in place.

The graph accumulates across dimensions: one intersecting polyarchy, not four separate charts. People are shaded by degrees of separation from the focus (blue ramp); groups, roles, apps and attribute hubs wear the colour of the relationship that connects them — matching their edges — faded with distance so the hop cue survives. Light and dark theme follow your MCP client.
