PostSiderとは？
PostSider is a social media scheduling and publishing platform that brings multiple channels into one calendar. Users can compose posts, attach media, plan content on a weekly or monthly grid, and publish to more than 30 networks. Content can be tailored per platform, while queues support recurring publishing times and best-time scheduling.
The product supports dashboard-based publishing as well as programmatic workflows. Developers can use its REST API, OpenAPI documentation, TypeScript/Node.js SDK, and—on applicable plans—webhooks. AI agents can connect through the Model Context Protocol (MCP) server to draft, schedule, publish, and access analytics alongside human users.
PostSiderでできること
Composer and media library
Write posts with inline formatting, attach images or videos, and use a shared media library. Content can be adapted for individual platforms before publishing.
Queues, bulk import, and automation
Create recurring time-slot queues, use best-time scheduling, add first comments or thread replies, and import a month of planned posts from a CSV file.
AI-agent and developer access
Connect compatible agents through MCP, or integrate with the REST API and official TypeScript/Node.js SDK. The developer platform provides named agent tools, OpenAPI documentation, and programmatic scheduling.
Team review and reporting
Use approval workflows, Owner/Editor/Viewer roles, cross-platform analytics, and PDF or CSV report exports to manage publishing and measure reach, impressions, and engagement.
Security controls
PostSider states that channel tokens are encrypted at rest with AES-256-GCM and isolated per channel, with least-privilege access, SSRF and CSRF protections, and rate limiting.
利用シーン
“Creators publishing across channels”
A solo creator can compose content once, adjust it for different networks, organize media, and manage a month of posts from a single calendar instead of switching between platforms.
“Brand and marketing teams”
Teams can share channels and media, assign roles, send drafts through approval, and use queues to keep recurring content moving without requiring every contributor to manage publishing settings.
“Agencies managing multiple brands”
Agencies can organize larger channel portfolios with higher channel and seat limits, shared workflows, audit logs, approvals, and reporting across client accounts.
“AI-assisted publishing workflows”
An AI-agent builder can connect an MCP-compatible agent to draft and schedule content, or use the REST API and SDK to add publishing and analytics to an internal application or automation.
“Migration from another scheduler”
Teams moving from Buffer or Hootsuite can connect PostSider alongside their existing tool, rebuild posting slots, import queue data by CSV where useful, and run both systems during an overlap period.
よくある質問
Which social networks does PostSider support?
The site says PostSider supports more than 30 networks, including X, Instagram, TikTok, YouTube, LinkedIn, Facebook, Pinterest, Discord, Telegram, Mastodon, and Bluesky. The platform list may expand over time.
How can an AI agent connect to PostSider?
PostSider provides an MCP server that compatible agents can discover and call. The site specifically mentions Claude, Codex, Cursor, GPT, and custom MCP agents; developers can also use the REST API or SDKs directly.
What is included in the trial?
The trial lasts seven days and includes the full product, including the calendar, composer, agent bridge, and API. No credit card is required to start.
Can teams review posts before they are published?
Yes. Approval workflows let reviewers approve drafts, reject them with comments, or request changes. Role-based access includes Owner, Editor, and Viewer roles.
How does migration from Buffer or Hootsuite work?
The recommended process is to connect channels to PostSider in parallel, rebuild posting slots in its calendar, move the queue manually or through CSV import, and run both tools for an overlap period before canceling the previous scheduler.
