Social Media

Social Media

A single publishing target for every social network you connect. Agents and workflows hand off a generic social post, and this connector routes it to whichever provider you have installed and signed in to — so the same workflow can post to a new network the day you add it.

Install this connector from the Cinatra marketplace. Once installed it activates automatically alongside any social-network provider connector (such as the LinkedIn connector). No additional configuration is required: the connector reads the authenticated user's identity from the platform session and picks the right provider at post time.

To publish a post, call the social_media_publish MCP tool with four fields: accountId (the provider account identifier), destinationType (either member for a personal profile or organization for a company page), destinationId (the provider-specific profile or page ID), and content (the post text). Pass an optional connectorId to target a specific provider when more than one is connected. On success the tool returns a publish receipt from the provider. If no provider connector is installed or the user is not authenticated, the tool returns a descriptive error identifying which step failed.

The connector exposes registerSocialMediaConnector, publishSocialMediaPostThroughSystem, getSocialMediaConnectorStatusThroughSystem, and listInstalledSocialMediaConnectors from its public package surface for host-side integration. Provider connector packages (for example a LinkedIn or Threads connector) import only the contract types (SocialMediaConnector, SocialMediaPost, SocialMediaPublishReceipt) as import type and register themselves behind the social-post capability from their own server entry. Run vitest run in the package directory to execute the test suite; no environment variables or network access are needed for the unit tests.
