Use case
Cross-post to every social platform at once
With Modiva you publish once and fan out everywhere: a single `posts_cross_post` call sends your content to every connected platform, adapted to each one's format and limits.
The problem
Posting the same update to a dozen networks means logging into each one, reformatting, and doing it again tomorrow. Building it yourself means a separate API, OAuth flow and format quirk per platform.
How Modiva does it
Connect your platforms once
Add each account through Modiva's hosted OAuth — tokens are stored encrypted and refreshed automatically.
Call posts_cross_post
Send your text and media once with a list of connection IDs. Modiva validates each platform's rules (length, aspect ratio, media types) and publishes everywhere.
Let an agent do it
Over the MCP server, an AI agent can take a single prompt and cross-post to every channel on its own.

Does each platform get the right format?
Yes — Modiva adapts the post to every platform's length, media and aspect-ratio rules before publishing.
Can I exclude a platform per post?
Yes — you pass the exact connection IDs to target, so each post can hit any subset of your accounts.
