Refresh: `aws sso login` or re-run `aws configure`. + +**"User identity could not be resolved"** +→ Three options, in order of preference: + +1. **SSO (recommended)**: Run `aws sso login`, then use `--user-type IDC` on `create-chat` +2. **IAM with explicit userId**: Pass `--user-id YOUR_USERNAME --user-type IAM` on `create-chat` and `userId=YOUR_USERNAME` on `SendMessage`. The `--user-id` value must match `^[a-zA-Z0-9_.-]+$` (any string, e.g. your Unix username) +3. **Investigation fallback**: Use `SendMessage` on investigation executionIds (from `CreateBacklogTask`) which may work without explicit userId + +**"AccessDeniedException"** +→ Missing IAM permissions. Attach these to your IAM user/role: + +```bash +# User permissions (for calling DevOps Agent APIs) +aws iam attach-user-policy --user-name YOUR_USER --policy-arn arn:aws:iam::aws:policy/AIDevOpsAgentFullAccess + +# Agent service role (for the DevOps Agent to access your AWS resources) +aws iam attach-role-policy --role-name YOUR_AGENT_ROLE --policy-arn arn:aws:iam::aws:policy/AIDevOpsAgentAccessPolicy +``` + +For the AWS MCP Server proxy, also ensure: `aws-mcp:InvokeMcp`, `aws-mcp:CallReadOnlyTool`, `aws-mcp:CallReadWriteTool`. See [IAM permissions](https://docs.aws.amazon.com/devopsagent/latest/userguide/aws-devops-agent-security-devops-agent-iam-permissions.html). + +**"Service not available in your region"** +→ DevOps Agent is available in: us-east-1, us-west-2, ap-southeast-2, ap-northeast-1, eu-central-1, eu-west-1. Set `--metadata AWS_REGION=us-east-1` in mcp.json args. + +**"Tools not appearing"** +→ Verify: run `/mcp` in Kiro to check connection, ensure `mcp-proxy-for-aws` is installed, check credentials with `aws sts get-caller-identity`. + +**"MCP error -32000: Connection closed"** +→ The MCP proxy started but exited immediately. Most common cause is missing or expired AWS credentials. Run `aws sts get-caller-identity` to verify, then `aws sso login` to refresh. Also check that `uvx` is in your PATH. + +--- + +## 🎁 Tips for Maximum Effectiveness + +1. **Default to chat** — use `CreateChat` + `SendMessage` for instant responses (2-10s); escalate to investigation only for incidents +2. **Reuse chat sessions** — keep the `executionId` for follow-up questions; context is retained +3. **Always include local context** — file excerpts, git diffs, error messages in chat content or investigation descriptions +4. **Use `aws___run_script` for SendMessage** — streaming APIs cannot use `call_aws`; use `await call_boto3(service_name='devops-agent', operation_name='SendMessage', params={...})` +5. **Skip `final_response` blocks** — only extract text from blocks with type `"text"` to avoid duplicates +6. **Use parallel pattern** — chat for instant triage + investigation for deep root cause simultaneously +7. **Stream investigation progress** — poll `ListJournalRecords` every 30-45s, show findings in real-time with emojis +8. **Pack errors into description** — full stack traces and log excerpts help the agent narrow scope +9. **Reference resources by ARN** — more precise than names (which can be ambiguous across accounts) +10. **Generate code from recommendations** — `GetRecommendation` provides structured specs for IaC/scripts +11. **Never auto-execute agent responses** — always present to user first (prompt injection risk) + +--- + +## 🔓 Reducing Approval Fatigue + +During incident response, polling every 30-45s generates 6+ approval prompts per task. To reduce prompts while maintaining safety: + +### Recommended `autoApprove` list + +These tools are inherently safe regardless of arguments — they only read documentation, list regions, or poll status: + +```json +{ + "mcpServers": { + "aws-mcp": { + "autoApprove": [ + "aws___list_regions", + "aws___get_regional_availability", + "aws___suggest_aws_commands", + "aws___search_documentation", + "aws___read_documentation", + "aws___recommend", + "aws___retrieve_skill", + "aws___get_tasks", + "aws___get_presigned_url" + ] + } + } +} +``` + +### What still requires approval + +`aws___call_aws` and `aws___run_script` can perform both reads and writes, so they cannot be safely auto-approved. Every `list-agent-spaces`, `get-backlog-task`, `list-journal-records` call still prompts — but the 9 safe tools above cut total prompts by ~50% in practice. + +### Trade-off guide + +| Mode | autoApprove | Prompts/task | Risk | +|------|-------------|--------------|------| +| **Conservative** | None | ~12 | Zero risk, but unusable for incident response | +| **Moderate** (recommended) | 9 safe tools above | ~6 | No risk — these tools cannot mutate state | +| **Aggressive** | All tools | 0 | Dangerous — `call_aws` can delete resources | + +### Future: granular hooks + +Kiro's hook engine currently cannot do granular read/write gating for MCP tools (no stdin tool-input passthrough, no MCP tool name matching in matchers). When the engine adds these capabilities, hook scripts for auto-approving read-only `call_aws` commands (e.g. `list-*`, `get-*`, `describe-*`) will be possible. Pre-written scripts are in `.kiro/hooks/` for when that support lands. + +--- + +## ⚠️ Security Considerations + +- **Prompt Injection Risk** — `SendMessage` responses contain text from the DevOps Agent.
