Independent architecture planner · Source checked August 8, 2026

Plan the harness boundary before wiring the workflow

Choose who owns the Harness ARN, how actor and session memory is scoped, which model and capabilities are allowed, and whether private networking is justified. The planner turns those inputs into a review checklist; it does not deploy anything.

Architecture inputs

Describe one harness workload

Review output

Invoke-only, session-scoped baseline

  1. Give n8n invoke-only permission for an existing Harness ARN; keep deploy and update rights in the platform release path.
  2. Map an authenticated stable actor ID and persist a unique session ID for each conversation.
  3. Scope the execution role to the selected Bedrock model and one allowlisted read-only tool.
  4. Set iteration, timeout, token, idle-session, and lifetime caps from tested workload percentiles.
  5. Connect n8n execution IDs to CloudWatch traces; tag resources and assign a cleanup owner.

This output is not an AWS deployment, IAM policy, security approval, network validation, price estimate, or Flowith integration.

Five gates

A connected node is not a production boundary

01

Runtime owner

Choose whether n8n owns create/update or only invokes a platform-owned Harness ARN.

02

Identity map

Define authenticated actor IDs, conversation session IDs, and durable mapping storage.

03

Capability scope

Allow only the models, tools, Skills, secrets, and network paths the task needs.

04

Hard limits

Set workload-specific iteration, timeout, token, and runtime-session caps.

05

Cleanup owner

Tag and inventory Harness plus separately created memory, network, storage, and logs.

Continue by architecture decision

Setup guide

Install the verified node and choose create, update, or invoke mode.

AI Agent vs. Harness

Choose the workflow-native or separately managed runtime boundary.

Memory and identity

Map users, conversations, retrieval, retention, and truncation.

Tools, Skills, and VPC

Review capability provenance, permissions, credentials, and network reachability.

n8n AgentCore harness planner questions

It converts a few architecture choices into a local review checklist for lifecycle, identity, credentials, memory, tools, networking, limits, observability, and cleanup.
No. It runs entirely in the browser and does not access n8n, AWS, credentials, prices, accounts, or production configuration.
No. It identifies review areas only. Build and test least-privilege policies from current AWS documentation and the exact resources in your environment.
No. Subnets, security groups, DNS, endpoints, routes, egress, provider access, and dependent-service permissions must all be validated in the target VPC.
