Integration

PostFast integration

PostFast is a social media scheduler. Create and schedule posts (text, images, videos, carousels, Reels, Stories, Shorts, documents) for the X, Facebook, Instagram, TikTok, LinkedIn, YouTube, Threads, Pinterest, Bluesky, Telegram and Google Business Profile accounts connected in a PostFast workspace; a scheduled, approved post is published PUBLICLY at its time. List, read and delete posts, read post analytics and daily follower history, look up Pinterest boards, YouTube playlists, Google Business Profile locations, trending TikTok sounds and places to geotag, get upload URLs for media, create connect links that let someone add their accounts, and work the Social Inbox: read comments left on TikTok, Instagram, Facebook and Threads posts (commenters' personal data), reply publicly, send an Instagram private reply, hide or delete comments, and triage conversations. PostFast publishes through each network's official API with the access the account owner granted when connecting the account in PostFast. Left out: uploading the file bytes themselves (an HTTP PUT to the signed storage URL create_upload_urls returns, not a PostFast route) and the deprecated tiktokPrivacy setting. Authentication is a workspace API key (PostFast app, Settings, API Keys) sent in the pf-api-key header.

Connect PostFast How integrations work

Ask it in chat

Say what should happen.
The workflow builds itself.

When this happens, do that in PostFast.Built from the 24 PostFast tools below, on the connection you add once.

What you can do with PostFast

Each of these is one operation on one endpoint, available both as a workflow step and as a tool an AI agent can call on its own. Nothing bundles several operations into one action, so what a run did stays readable afterwards.

Each badge shows the default agent permission of an endpoint (allowed: an agent calls it without asking; ask first: you are asked before an agent calls it, when the agent or chat asks permission for sensitive actions; never: no agent may call it), which every user can change endpoint by endpoint in their credential settings.

Most endpoints run on the free plan. A few, mainly the ones that publish on your behalf, need a paid plan.

Use PostFast from Claude Code, Cursor or Codex

Connect PostFast in LiveContext, create an API key in Settings, then add the LiveContext MCP server to your client. Its PostFast operations become tools the client can call, next to every other integration you connected.

Claude Code

claude mcp add --transport http livecontext https://livecontext.ai/mcp --header "X-API-Key: YOUR_API_KEY"

Codex (~/.codex/config.toml)

[mcp_servers.livecontext]
url = "https://livecontext.ai/mcp"

[mcp_servers.livecontext.http_headers]
"X-API-Key" = "YOUR_API_KEY"

Cursor, Claude Desktop and other JSON configs

{
  "mcpServers": {
    "livecontext": {
      "type": "http",
      "url": "https://livecontext.ai/mcp",
      "headers": {
        "X-API-Key": "YOUR_API_KEY"
      }
    }
  }
}

How to connect PostFast

Create your workspace
Sign up free. Nothing to install.
Connect PostFast once
Add your PostFast connection in Settings. Every tool from this integration reuses it, and secrets are encrypted at rest and visible only to you.
Describe the job in chat
The workflow builds itself in front of you and picks the endpoints it needs. Drag the steps yourself on the canvas whenever you would rather be explicit.
