PostSider

PostSider is a social media scheduling and publishing platform for creators, teams, agencies and developers managing multiple networks. It combines a visual calendar with MCP, REST API and SDK access so people or AI agents can draft, schedule and publish content.

PostSider

Social media scheduling for people and AI agents

PostSider is a social media scheduling and publishing platform for creators, founders, agencies and teams managing multiple brands or channels. It combines a drag-and-drop content calendar, composer, media library, previews, queues and analytics so users can plan and publish from one workspace.

The product also provides a machine-accessible publishing layer: an MCP server for AI agents, plus a REST API and SDKs for custom workflows. Users can connect more than 30 social networks, create posts themselves or delegate drafting and scheduling to an agent, then publish through the same connected-channel setup.

Core features

Drag-and-drop scheduling

Plan content on a visual calendar, drag posts between days and channels, duplicate posts to another network, and use queue slots or best-time scheduling.

Cross-platform composer

Compose once, adapt content for individual networks, manage media, and review live previews before publishing.

MCP, REST and SDK access

Connect Claude, Codex, Cursor or another MCP-compatible agent to draft, schedule and publish. The same publishing workflow is also available through a typed REST API and SDKs.

30+ social networks

Publish to more than 30 networks from one calendar, with platform-specific tailoring available instead of relying only on an identical cross-post.

Cross-channel analytics

Review reach and performance across channels, with basic analytics on Standard and advanced analytics on higher plans.

Security controls

Protect connected channel tokens with AES-256-GCM encryption at rest, alongside SSRF and CSRF protections, rate limiting and per-channel isolation.

Who uses PostSider

  • Creators and solo founders

    Plan a month of posts in one calendar, move content between days or channels, and use previews and media management before publishing across multiple networks.

  • AI-assisted publishing

    Connect an MCP-compatible agent to draft posts, fill the queue and publish through conversational commands, without building separate integrations for each network.

  • Agencies and brand teams

    Coordinate several brands or social channels with shared queues, team seats, approval workflows and multi-user roles available on applicable plans.

  • Developer workflows

    Use the REST API, SDKs or webhooks on applicable plans to connect social publishing and analytics to custom applications, scripts or internal pipelines.

Cons
