Verdicts

Microsoft Entra Agent ID

Agent identities hold no credentials of their own, and Entra refuses high-privilege roles and Graph permissions for them. The token flow is a two-step exchange that Microsoft's own docs call complex and error-prone to implement by hand, and Conditional Access, risk detection and governance for agents need a paid Agent 365 licence.

Scalekit AgentKit

500+ connectors, including remote MCP servers over OAuth 2.1 with DCR. No rate limits or idempotency documented for Scalekit's own API.

Before you call either

Microsoft Entra Agent ID

  1. Request tokens in two steps. The blueprint gets an exchange token with fmi_path set to the agent identity's client ID, then the agent identity trades it for a resource token
  2. Retry with exponential backoff when a create returns 400 Object with id not found straight after creating its parent object
  3. Send displayName, agentIdentityBlueprintId and a sponsor reference when creating an agent identity. All three are required
  4. Don't use the interactive /authorize flow. Agent identities are confidential clients and can't sign in to a page
  5. Keep the sidecar off any public network. Its /AuthorizationHeader endpoint hands out tokens to whoever can reach it

Scalekit AgentKit

  1. Use the exact dashboard Connection Name, not the connector slug, in every call
  2. Call POST /api/v1/tools:search with top_k instead of listing every tool
  3. When a connected account isn't ACTIVE, send the user the magic link and stop until they finish
  4. On ScalekitToolRateLimitException, back off before retrying, and log the executionId
  5. Mint a fresh virtual MCP session token per user per run and let it expire
