Choosing a social media scheduler with an API or MCP server for AI agents
· OragleGPT
If you want an AI assistant or a script to schedule your social posts, the scheduler's API matters more than its calendar view. Here is what to compare, and where GPTpost stands on each point.
1. Is the API on the plan you will actually buy?
Several tools reserve API access for top tiers. When we checked public pricing pages on 15 October 2026, Metricool listed its API on the Advanced plan and Planable listed an MCP connector on paid plans. GPTpost includes the API and the MCP server on every plan, Solo USD 12, Team USD 39 and Agency USD 99 per workspace per month, and in the 14-day free trial.
2. MCP, OpenAPI or both?
MCP lets assistants such as Claude Code and Claude Desktop discover the tools on their own. An OpenAPI schema lets ChatGPT custom GPTs and agent frameworks do the same. GPTpost offers a remote MCP server at app.oraglegpt.org/mcp and an OpenAPI 3.1 schema at app.oraglegpt.org/openapi.json, with the same operations behind both.
3. Do approvals apply to the agent?
If the API can publish straight past your review process, every agent mistake is public. In GPTpost, posts created through the API go through the workspace's approval stages and per-network length checks, just like posts written in the app.
4. Which networks can the agent reach?
An API is only as useful as the networks behind it. GPTpost publishes today to Mastodon, Bluesky, Lemmy, X, DEV, WordPress, Telegram, Discord, Slack, Listmonk and Whop. Facebook Pages, Instagram, Threads, TikTok, YouTube, LinkedIn, Pinterest and Google Business Profile are built in and become available as each network completes its review of the app. If you need Instagram or TikTok publishing through an API today, choose a tool that has it live.
5. How is it priced as you add people?
Per-user pricing makes every new teammate or reviewer a cost. GPTpost is priced per workspace with a set number of seats per plan, and client reviewers using review links need no seat. See pricing and comparisons.
6. What does the agent get to read?
Some APIs expose inboxes and analytics. That is useful for reporting agents and a risk for drafting agents. GPTpost's agent API reads post status only; it does not expose comments, messages or network analytics.
Short version
If you want agents to draft and schedule posts across the fediverse, X and developer channels, with approvals enforced on the server and the API on every plan, GPTpost fits. If you need analytics, an inbox, or Instagram and TikTok publishing through an API today, look at the comparisons for a better fit.
