Building your own MCP server for social media gives exact control but means writing and hosting code for every platform API, app review, token refresh and rate limit. A hosted server such as SkedCast's gives Claude, ChatGPT, Muse or any MCP client tools to schedule, revise and report on posts, with that upkeep handled.
Key takeaways
- Building your own MCP server means owning OAuth, token storage, rate limits, and maintenance per platform you wrap.
- A hosted MCP server gives you multi-platform coverage and auth for free, in exchange for depending on that vendor.
- Build your own when you need a genuinely custom tool surface or are integrating one specific internal system.
- Use a hosted server when the value you’re adding is on top of publishing, not the publishing plumbing itself.

Build your own MCP server vs hosted: what building your own actually involves
An MCP server for social posting needs the same infrastructure a scheduling app needs (see the developer guide on building a scheduling app): OAuth per platform, encrypted token storage and refresh, a queue for scheduled actions, and per-platform adapters — PLUS the MCP protocol layer itself (tool definitions, a transport, auth for the MCP connection specifically). You own all of it, including keeping up with every platform’s API changes.
What a hosted server gives you
Multi-platform coverage, OAuth, rate limiting, and ongoing maintenance are handled by the vendor. You connect once and every supported platform is available through the same tool surface — the trade-off is depending on that vendor’s uptime, roadmap, and terms.
When to build your own
It makes sense when you need a genuinely custom or narrow tool surface (e.g. exposing only your own internal content-approval system, not a general posting tool), when you’re integrating exactly one platform and don’t want a dependency for that alone, or when the MCP server itself is your product.
When to use a hosted one
It makes sense whenever posting infrastructure is a means to an end for you, not the differentiator — an agency tool, an internal marketing workflow, a personal automation. The engineering cost of building and maintaining OAuth + queues + adapters per platform is real and ongoing; a hosted server removes it entirely.
FAQ
- Is a self-built MCP server more secure than a hosted one?
- Not inherently — security depends on implementation quality, not who built it. A well-built hosted server (scoped auth, confirm-before-write tools, encrypted token storage) can be more secure than a hastily-built custom one. Evaluate the specific implementation, not the build-vs-host choice alone.
- Can I combine both — a hosted server for most platforms, a custom one for one internal system?
- Yes — MCP clients can connect to multiple servers simultaneously, so this is a common and reasonable split: a hosted server for standard social platforms, plus a narrow custom server for something platform-specific to your own stack.
- Which AI assistants can connect to SkedCast?
- SkedCast is available as a connector in Claude, ChatGPT and Muse, and any other MCP client can use the same server.
- Can an AI assistant publish without my approval?
- Every tool that changes something is marked as a write, so the assistant's host asks you to confirm, and SkedCast's approval steps still apply.
- Which SkedCast plan includes the MCP server?
- MCP access is included from the Solo plan up.
