Run Knowledge Brain agent review actions: list_reviews, list_comments, list_health_findings, list_changed_files, list_requested_revisions, or mark_fix_ready.

## Connect and discover

Connect an authenticated [MCP client](/docs/build/mcp). Call `tools/list` to confirm this tool is available to the current credential. Provider, workspace, and agent grants remain separate access checks.

## Input fields

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `action` | `"list_reviews"` · `"list_comments"` · `"list_health_findings"` · `"list_changed_files"` · `"list_requested_revisions"` · `"mark_fix_ready"` | Yes | Operation to perform. Choose one advertised value; the remaining parameters are interpreted for that action. |
| `provider` | `"github"` | No | Source provider for the review. Commentary currently accepts GitHub for provider-backed MCP operations. |
| `owner` | string | No | Repository owner or organization login. |
| `repo` | string | No | Repository name without the owner prefix. |
| `prNumber` | number | No | Pull request number within the selected repository. |
| `branchRef` | string | No | Repository branch name or fully qualified branch reference. |
| `rootFolder` | string | No | Root folder used by the selected Knowledge Brain Review action. |
| `filePath` | string | No | Repository-relative or review-relative file path. |
| `state` | string | No | State filter supported by the selected action. |
| `threadId` | string | No | Stable Commentary review-thread identifier. |
| `bodyMarkdown` | string | No | Markdown body for the comment, reply, note, or report produced by the selected action. |
| `agentAlias` | string | No | Stable agent identifier for agent-authored activity. Agents should always provide this on state-changing calls; clientName is not a substitute. |

## Call the tool

Send a `tools/call` request with `name: "brain_review"` and an `arguments` object containing the required fields above. Choose an advertised action, then supply the fields required by that action. Do not treat a successful request as human approval or verified execution unless the returned contract explicitly records that fact.

## Errors and recovery

Read the returned error and permission requirements. Refresh stale revisions before conditional writes, retain idempotency keys only for exact retries, and reconnect when a credential has expired.
