Overview

AI-generated overview

Lets an assistant publish, schedule, and manage social media posts across 13+ platforms through the PostBolt API.

What you can do
Provides tools to publish a post immediately to one or more platforms, schedule a post for a future time, list and inspect posts with per-platform results, update or cancel scheduled posts, and upload an image to attach. It also exposes resources for the account profile (plan, quota, allowed platforms) and connected social accounts.
When to use it
Useful when you want an assistant to draft and push content to multiple social networks from one place, queue posts for later, or check how a post performed per platform without opening each network's own dashboard.
Requirements
Runs locally over stdio, typically launched with npx, so Node.js is needed. Requires a PostBolt account and an API key supplied as the POSTBOLT_API_KEY environment variable. Network access to the PostBolt API is required. Desktop MCP clients only.
Before you install
The API key (POSTBOLT_API_KEY) is a secret that grants access to your PostBolt account and connected social accounts; keep it out of shared configs. Publishing and scheduling write publicly visible content, and cancel_post changes state. Posting consumes plan quota, and platform availability depends on your plan.

Installation

In SourceWeft

  1. Open Postbolt in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.
