At a Glance & Executive Verdict
Solnk MCP
Social Media · Local stdio
Quality: 55/100 (Good) | Auth: API Key required
Posthive
Social Media · Remote HTTP/SSE
Quality: 53/100 (Good) | Auth: OAuth 2.0
Verdict Summary: Choose Solnk MCP if you need specialized Social Media tools running via a local process. Choose Posthive if your workspace requires Social Media integration with remote web transport. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Solnk MCP when:
You need dedicated capabilities in the Social Media domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: API Key required (BYOK (Pay Provider Direct)).
List teams owned by the connected Solnk user. Call this before solnk_delete_team to identify the protected default team, the API-key team, and a destination team for migrated content.
solnk_set_default_team
Make the connected API-key team the owner's default team. The default team is used as the fallback after leaving a shared team and is preselected as the migration destination when deleting another team.
solnk_delete_team
Permanently delete an extra team after the user explicitly requests it. The connected API key must belong to the deleted team. Accounts, posts, groups, and media move to destination_team_id; memberships, source-team API keys, webhooks, and invitations are removed. The default team cannot be deleted. Success revokes the current API key, so the MCP connection must be reconnected to a key in the destination team.
solnk_list_accounts
List the user's connected social accounts (id, platform, username, status, capabilities). Call this first to get account_id values for publishing.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Solnk MCP is categorized under Social Media and uses a local stdio subprocess. In contrast, Posthive belongs to Social Media using remote streaming HTTP/SSE transport. Select Solnk MCP when you need capabilities focused on social media and Posthive when you require tools for social media.
Get the user's plan limits and current usage. Check `can_publish` is true before publishing.
solnk_publish
Publish content to one or more platforms in a single request. Use publish_mode 'draft' to stage for review (then solnk_confirm_publish), 'scheduled' with scheduled_at, or 'immediate' to send now. Reuse the same idempotency_key when retrying the same logical publish. If omitted and a network/503 error occurs, the error details include the generated key to reuse. NOTE: if the team requires approval and this key is not an owner/admin, the response comes back with status 'awaiting_approval' (approval_status 'pending_approval') and is NOT published until a team owner/admin approves it (solnk_approve_publish).
solnk_confirm_publish
Confirm an unconfirmed draft so it goes out. Omit scheduled_at to publish immediately, or pass it to schedule. This tool never reschedules an already-confirmed publish; use solnk_reschedule_publish explicitly for that. If queue dispatch returns a 503, retry this same call safely: Solnk redelivers using the same deterministic job ID. NOTE: if the team requires approval and this key is not an owner/admin, confirming returns status 'awaiting_approval' and the draft is held for a team owner/admin to approve rather than published.
solnk_update_publish
Update an existing draft or not-yet-sent scheduled publish in place. This preserves the same publish_id and, for scheduled posts, the existing publish time. Never cancel and recreate a publish just to edit it. When targets is provided it is the complete replacement target list, not a partial list.
solnk_update_draft
Backward-compatible alias for solnk_update_publish. Updates the same draft or not-yet-sent scheduled publish in place and preserves its publish_id.
solnk_reschedule_publish
Move a not-yet-sent scheduled publish to a new future time without creating a new publish. Preserves the same publish_id, content, media, and targets; only the queue time changes.
solnk_cancel_publish
Cancel a draft publish. Cannot cancel one already queued, processing, or published.
solnk_unschedule_publish
Cancel the future delivery of a not-yet-sent scheduled publish and restore the same publish to an editable draft. Preserves publish_id, content, media, and targets; does not create a replacement. Use solnk_confirm_publish to schedule or publish it again later.
