READ the defect board (defects + incidents), newest first. Call this BEFORE filing a
defect, to check it is not already reported. Filter by `status` ("open" | "closed") and/or
`severity`. Returns {"count": N, "defects": [{defect_id, title, status, severity, component,
spec_ref, reporter, last_seen}]}. Needs the `manage_task` capability. (A per-defect change
log does not exist yet — only tasks carry one.)

**Access:** read-only — safe to call repeatedly, changes nothing

**Available at:** `/mcp/`, `/mcp/readonly/`

_Hints declared to MCP clients (ToolAnnotations)_

| Hint | Value |
| --- | --- |
| `readOnlyHint` | true |
| `destructiveHint` | false |
| `idempotentHint` | true |
| `openWorldHint` | false |

## Parameters

| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `status` | `string \| null` | no | open or closed; omit for both |
| `severity` | `string \| null` | no | sev1 … sev4 |
| `limit` | `integer` | no | Maximum number of defects to return |


## Example call

Send inside an initialized MCP session (see [Connecting](../../connecting/)). Every parameter is shown with a typed placeholder; drop the optional ones you do not need — but for defect/task tools the QA fields are what keeps a report out of quarantine.

## If it fails

| Symptom | Cause | Action |
| --- | --- | --- |
| `401` | Token missing/expired | Tokens are issued by the platform owner via `POST /api/v1/auth/agent-token` (superuser-only) — ask for a re-issue. ⚠️ A new token **replaces** your grant set |
| `403` / capability error | Your token lacks the capability or the contract grant | Check `my_capabilities` first; ask the owner for the grant |
