A content calendar built manually usually means a spreadsheet, a handful of ideas, and a lot of back-and-forth deciding what goes where. Claude, connected to OneUp's MCP server, can compress that planning process into a conversation — and schedule the result directly, instead of handing you a plan you still have to enter manually.
What this actually looks like
Rather than asking Claude for content one post at a time, you describe your goals and constraints, and Claude proposes a structured calendar — themes, posting cadence, platform mix — that you can revise conversationally before anything gets scheduled.
Setting up the connection
- Generate your OneUp API key (gear icon → API and MCP).
- In Claude, go to Settings → Connectors → Add Custom Connector, and use OneUp's MCP connector URL with your API key appended.
- Confirm OneUp appears as an active connector.
A prompt for building the calendar itself
"I run a [type of business]. Help me build a 2-week content calendar for Instagram and LinkedIn, mixing educational posts, behind-the-scenes content, and one promotional post per platform per week. Show me the plan first before scheduling anything."
Asking Claude to show the plan before scheduling gives you a review step — you can adjust the mix, swap a day, or change a theme before any of it actually gets queued in OneUp.
Turning the approved plan into scheduled posts
Once you're happy with the plan:
"Great, now write the captions for each of these, source images where needed, and schedule them to my [Account Name] and [Account Name] profiles accordingly."
Why the two-step approach works better than one big prompt
Asking for a full calendar and immediate scheduling in a single prompt skips the review step that catches a lot of small issues — an unbalanced content mix, a theme repeated too close together, a day that got missed. Separating "plan" from "execute" gives you a natural checkpoint without adding much extra effort.
Where this is most useful
This works best for accounts that know their general content pillars but don't want to spend an hour each week manually planning the specific mix — Claude handles the planning structure, you handle the approval, and OneUp handles the actual publishing.
