Post to Social Media with Muse

Meta Wired Up Its Own Platforms. The Rest Are On You.

Muse's launch connector list covers Gmail, Google Calendar, Spotify, OpenTable, Ticketmaster, Plaid, Apple Health and more - and Facebook, Instagram and Threads connect automatically through Accounts Center. Every non-Meta social platform is absent.

That's a reasonable launch scope, purposely. Meta shipped its own surfaces first, the same way most platforms do. But if your audience lives on TikTok, LinkedIn, YouTube, X, Pinterest or Bluesky, that's most of your actual publishing.

The practical consequence: Muse will happily write your TikTok caption and your LinkedIn post. It just can't publish them.

Honest note - Muse is US-only at launch.

Muse Builds Its Own Connectors, If You Give It the Right Link

Muse reaches outside services three ways.

The second tier is what matters here. Muse accepts an MCP server URL, a REST API or OpenAPI document, or a CLI package name, and builds a working connector from it. Meta's release notes for Muse Spark 1.1 describe the model as zero-shot generalizing to new tools, MCP servers, and custom skills; this is designed behavior, not a workaround someone found.

Set your expectations accurately: one message, roughly a minute, and Muse saves the result as a reusable skill you can call again without rebuilding it.

WoopSocial Is the Connector Muse Is Missing

WoopSocial is a unified social media API and MCP server. One connection gives Muse TikTok, LinkedIn (personal profiles and company Pages, as separate targets), YouTube, X, Pinterest and Bluesky, and it covers Facebook, Instagram and Threads too, if you'd rather run everything through one place instead of splitting native and bridged connections. For Reels, Stories and feed posts, see the Instagram posting API.

Approvals are the biggest value driver here. Several platforms gate publishing behind review before you can use their API for real: TikTok's Direct Post audit, LinkedIn's Community Management API approval, Google's OAuth verification for YouTube. WoopSocial has already passed all of them. You skip the queue entirely, building these yourself means weeks of review, with no guarantee of passing the first submission.

Scheduling: publish now, schedule for later, or save as a draft - so Muse can queue a week of content instead of firing one post at a time.

Reliability built for agent use: posts atomically validate, if one target fails in a multi-platform request, no post publishes, so you'll never have a post that is half-published and lives on three platforms and is missing on a fourth. Delivery failures worth retrying, a timeout, a temporary rate limit, will automatically retry; failures that require you to actually do something, a disconnected account, no credits, will not silently retry themselves into a dead end.

Per-platform adaptation: one request can carry different text and media for each platform, so Muse can write a LinkedIn version and a TikTok version of the same update in the same breath.

Credentials: Muse never holds your platform passwords, only your WoopSocial API key.

Connect Muse to Your Social Platforms in 3 Steps

Step 1: Get your WoopSocial API key

Free, about 70 seconds. Connect your accounts inside the WoopSocial dashboard, one platform or all of them at once.

Step 2: Give Muse the link

One message, roughly: "Build a custom integration for WoopSocial using this MCP server: https://api.woopsocial.com/mcp?api_key=YOUR_WOOPSOCIAL_API_KEY. Use bearer token auth with this API key. Test it and save it as a skill."

Muse handles the transport and auth questions itself, for a hosted MCP server the answers are usually HTTP and bearer token.

Step 3: Tell Muse to post

"Post this to TikTok, LinkedIn and YouTube, and schedule the Pinterest version for Thursday morning."

You are not writing code. You hand Muse a link and let it do the integration work - exactly what it was built for. And because Muse asks before publishing anything, you'll see a confirmation before a post actually goes out, you stay in control the whole time.

Pick Your Platform

Every platform has its own quirks. Here's what WoopSocial handles for each.

• TikTok — the heaviest API of the lot. Skip the Direct Post audit entirely, WoopSocial handles the required fields including AI-generated-content disclosure, privacy level, and duet/stitch/comment settings.
• LinkedIn — LinkedIn's own API has no scheduling endpoint at all. WoopSocial adds scheduling LinkedIn doesn't offer, and covers personal profiles and company Pages as separate targets.
• YouTube — unit-based quotas, no service accounts, resumable uploads. WoopSocial handles title, privacy, tags, category and made-for-kids in one call.
• X — the only paid social API, billing per post with a steep surcharge on posts containing links.
• Pinterest — board targeting is mandatory. WoopSocial handles board selection, Pin title and destination link.
• Bluesky — decentralized, still young as a publishing target for most tooling. WoopSocial handles the account resolution and posting so it's one more platform in the same message, not a separate setup.

If you'd rather manage Facebook, Instagram and Threads alongside everything else in one place, WoopSocial covers those too, but Muse already connects them natively, so that's a preference, not a gap.

Built for Agents, Not Just Dashboards

The same backend serves the web app, the REST API, and MCP-compatible agents, the connector you give Muse is the same one powering everything else.

Pricing is flat and predictable: free to start, $19/month for Pro, scaling to $49 for Business and $799 for Max, with API and MCP access included on every tier, free included.

WoopSocial maintains every integration and keeps platform approvals current - deprecations and policy changes are its problem to track, not yours.

And it's portable: a standard MCP server and REST API mean the same connection works with other agents too, Claude, Cursor, n8n, if your stack changes later, you're not rebuilding from scratch.

Muse Already Writes Your Posts. This Is How It Publishes Them.

You already have Muse. Closing the gap to TikTok, LinkedIn, YouTube, X, Pinterest and Bluesky is one message and a free API key, not a developer account, not code, not a weeks-long review queue.
