What is an Agent Session?
An Agent Session is a programmatically provisioned runtime instance that couples:- 1 tenant-level agent (created via AMS SDK)
- Knowledge sources (contexts OR RAG MCP)
- Tool integrations (MCP servers)
- 1 specific end-user (identified by
externalUserId)
Key Concept: Agent sessions enable dynamic, per-user permission control. The same agent can be provisioned with different knowledge sources and tools for different users based on your platform’s permission system.
Agent Session Composition Rules
Rule 1: Knowledge Sources (Mutually Exclusive)
Choose ONE option:Option A: Contexts
Up to 30 context UIDs
Option B: RAG MCP
Exactly 1 RAG-type MCP
Rule 2: MCP Servers (Maximum 5 Total)
- RAG-type MCP: 0 or 1 maximum per session
- Tools-type MCPs: 0 to 5 per session
Valid example: 1 RAG MCP + 4 Tools MCPs = 5 total
Rule 3: Tags (Maximum 10)
Used for reporting, grouping, and filtering agent activity.Valid Configuration Examples

Deployment Flow
1
Tenant Creates Agent via AMS SDK
Tenant admin uses
<mindset-agents-manager> to create and configure agentLearn more about AMS SDK2
Your Backend Determines Permissions
Based on your platform’s permission system, determine which contexts/MCPs the end-user can access
3
Create Agent Session via API
POST to AgentSessions API with:
4
Receive agentSessionUid
API returns unique session identifier (e.g.,
"agent-123::session-789")5
Embed Agent in User's UI
Use
<mindset-agent> tag with agentSessionUid:Critical Security Note: Tenant Isolation
Agent Session Lifecycle
- Created on-demand: Generate new session each time user accesses agent
- Auto-expires after 31 days of inactivity: Sessions become inactive if not used
- Can be manually deleted via API: DELETE endpoint available for immediate deactivation
- Multiple sessions per user allowed: Same user can have multiple active sessions with different configurations
