Architecture

MCP Client (Claude, etc.)
    |
    | stdio (JSON-RPC)
    v
agentrux-mcp (this server)
    |
    | HTTPS (JWT auth)
    v
AgenTrux API Server
    |
    +-> JetStream (events)
    +-> MinIO (large payloads)
    +-> PostgreSQL (metadata)

The MCP server authenticates on first tool/resource call using AGENTRUX_SCRIPT_ID and AGENTRUX_CLIENT_SECRET to obtain a JWT. Token refresh is handled automatically by the SDK.
