Inspect review document structure with action=list_blocks for PR/branch rendered Markdown anchors or Draft Review latest-revision blocks, action=list_files for Draft Review file metadata, or action=get_progress/get_file_progress/get_changed_since_reviewed/get_unreviewed_files for read-only review progress.

## 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_blocks"` · `"list_files"` · `"get_progress"` · `"get_file_progress"` · `"get_changed_since_reviewed"` · `"get_unreviewed_files"` | 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. |
| `filePath` | string | No | Repository-relative or review-relative file path. |
| `fileId` | string | No | Stable Commentary file identifier returned by the review or revision API. |
| `sessionId` | string | No | Stable Draft, or Research session identifier, as applicable to the selected tool. |

## Call the tool

Send a `tools/call` request with `name: "review_document"` 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.
