# suggest_broadcast

> Suggests other platforms where the brand could broadcast a piece of existing content.

Suggests other platforms where the brand could broadcast a piece of existing content. Read-only — never creates drafts. Pair with [`create_content_draft`](/mcp/writes/create-content-draft) to actually write the cross-post.

## Inputs

`source_content_id` — id of an existing content row that belongs to the authenticated brand. Returns ranked platform suggestions with rationale strings.

## When to use

* The user has a successful post on one platform and asks "where should I post this next?"
* You're about to call `create_content_draft` and want to pick the highest-headroom platform.
* The user wants to cross-post but doesn't know which channels are underused.

## When not to use

* The user wants attribution data — use [`get_attribution_report`](/mcp/reads/get-attribution-report).
* The user wants overall AI visibility — use [`get_brand_visibility`](/mcp/reads/get-brand-visibility).

## Ranking

Higher score = more cross-post headroom on that platform. Excludes the source platform. Window defaults to 30 days.

## Response

```
{ source: { contentId, platform, title, postedUrl, postedAt },
  windowDays,
  suggestions: [{ platform, recentPostCount, score, rationale }] }
```
