Post Bridge MCP server

Post Bridge Agent Mode

Give your AI agent the ability to post to 10 social media platforms from a single command.

Supports: Instagram, TikTok, YouTube, X (Twitter), LinkedIn, Facebook, Pinterest, Threads, Bluesky, Google Business

Built on the Post Bridge API. Post Bridge is a social media scheduling tool used by 1,500+ creators and teams to post everywhere from one place.

Agent Plugins standard

This repo is also a portable Agent Plugin (spec 1.0.0), the open packaging standard from Amazon, Cursor, Microsoft, OpenAI, and Vercel. Root plugin.json + mcp.json + skills/ mean any compatible client (Cursor, VS Code, and more as they adopt it) can load the post bridge skill and connect to the hosted MCP server from this one package. Claude Code keeps using .claude-plugin/ as before; both formats live side by side.

What Are Skills?

Skills are markdown files that give AI agents specialized knowledge and workflows for specific tasks. Add this to your project and your AI agent will be able to create, schedule, and publish social media content across 10 platforms.

Install

Skill (works with Claude Code, Cursor, Windsurf, Codex, and other agents):

npx skills add post-bridge-hq/agent-mode

This installs the skills and makes the postbridge-cli CLI available to your agent.

Two skills ship in this repo:

Install just one with --skill:

npx skills add post-bridge-hq/agent-mode --skill b2c-organic-social-media-marketing

CLI only (no skill, any terminal):

The CLI is published standalone on npm — no install required, npx fetches it on first use:

npx postbridge-cli setup --key pb_live_xxxxx
npx postbridge-cli accounts

Requires Node.js 18+. Install globally with npm i -g postbridge-cli if you'd rather drop the npx prefix.

Other installation methods

Setup

1. Sign up at post-bridge.com and connect your social accounts
2. Enable API access (API Keys page in your dashboard) — $5/month add-on
3. Run the setup command:

npx postbridge-cli setup --key pb_live_xxxxx

Tip: You can also set the API key as an environment variable instead of running setup: export POSTBRIDGEAPIKEY=pblive_xxxxx (add it to ~/.zshrc / ~/.bashrc to persist).
