The PostSider Agent Bridge is the interface between AI agents and the social web. Instead of building a custom integration for every platform, your agent connects to PostSider once and can publish, schedule, validate, and analyze content across the supported social channels: X, LinkedIn, Instagram, TikTok, Bluesky, YouTube, and more. Whether you are automating a content pipeline, building a social copilot, or orchestrating multi-platform campaigns, the Agent Bridge gives you a clean, auditable surface that works with any MCP-compatible runtime or HTTP client.

​
Three ways to connect

PostSider supports three integration patterns. Choose the one that best matches your agent’s runtime and your team’s tooling.

MCP Server

A developer tool for AI agents. The repository ships @postsider/mcp, exposing 17 tools. Build it from source yourself; it is not on npm and has no dashboard page. Configure both the API key and instance URL for Claude Code, Claude Desktop, Codex, or any MCP runtime.

REST API

Versioned /public/v1 endpoints for any HTTP client. Authenticate with an API key in the Authorization header and call endpoints from scripts, CI pipelines, or custom agents.

SDK

The @postsider/node npm package wraps the REST API with full TypeScript types. Install it in any Node.js project for the fastest programmatic path to publishing.

​
What agents can do with PostSider

Once connected, your agent has the same publishing surface you have in the dashboard:
  • Publish, schedule, or draft posts across one or more connected channels in a single call
  • Find the next free queue slot for a channel (UTC) so scheduling respects your posting plan
  • List posts in a date range to review the content calendar
  • Validate a post per channel before publishing, then fix whatever is flagged
  • Change a post’s status or delete a post as your plan evolves
  • Upload images and video from a public URL into the media library, then attach them to a post
  • List connected channels and channel groups to get the ids every other call needs
  • Pull analytics at the post and channel level, where the platform supports it
  • Read notifications, such as publish failures or channels that need reconnecting
You need a PostSider API key to authenticate any Agent Bridge request. Generate one in the dashboard under Settings → API. See the Authentication page for full details.
