AutomateLab Content Distribution MCP

content-distribution-mcp

Publish your content everywhere—without rewriting for every platform.

A MCP server that distributes a single piece of content across 8+ channels (DEV.to, Hashnode, GitHub Discussions, Reddit, Bluesky, LinkedIn, Medium, Twitter) with automatic platform-specific adaptation, idempotent publishing, per-community anti-spam rules, and centralized state management.

The Problem It Solves

Creating and publishing content at scale is friction-heavy:

• Different formats: Reddit strips formatting, Twitter has character limits, DEV.to supports embeds and rich media. Each needs customized copy.
• Platform rules: Subreddits enforce cooldowns and flair requirements. Communities have posting patterns and automoderator gates. LinkedIn suppresses external links.
• State chaos: Which posts went live where? What if a publish fails halfway? Did that Reddit post get auto-removed by spam filters?

This MCP handles distribution complexity. Write your core message once, generate platform-specific variants, publish everywhere safely.

How It Works

1. Your agent generates channel-specific copy variants (rewritten titles, trimmed text, platform-appropriate tags, audience-matched tone).
2. This MCP publishes each variant with idempotency, OAuth, API retries, and scheduling—enforcing platform constraints automatically.
3. You control which platforms get what. The MCP returns per-channel hints (character limits, tag vocabularies, cooldowns) but leaves creative decisions to you.

No LLM calls inside. No walled-in agents. Just a clean API for multi-platform content distribution at scale.

Install

npx @automatelab/content-distribution-mcp

Or add it permanently to your MCP host.

Wire into your MCP host

Claude Code — add to .claude/mcp.json:

{
  "mcpServers": {
    "content-distribution": {
      "command": "npx",
      "args": ["-y", "@automatelab/content-distribution-mcp"]
    }
  }
}

Claude Desktop — add to claude_desktop_config.json:

{
  "mcpServers": {
    "content-distribution": {
      "command": "npx",
      "args": ["-y", "@automatelab/content-distribution-mcp"]
    }
  }
}

n8n — use the MCP Client node, point it at npx @automatelab/content-distribution-mcp over stdio.

Cursor / Windsurf / any MCP host — same npx -y content-distribution-mcp pattern.

Configure credentials

The server reads credentials from a Distribution Profile stored in ~/.distribution-mcp/profiles.yaml:

# ~/.distribution-mcp/profiles.yaml
default:
  credentials:
    DEV_TO_API_KEY: "your-devto-api-key"
    HASHNODE_TOKEN: "your-hashnode-token"
    HASHNODE_PUBLICATION_ID: "your-pub-id"
    GITHUB_TOKEN: "ghp_..."
    GITHUB_DISCUSSION_REPO: "owner/repo"
    REDDIT_CLIENT_ID: "..."
    REDDIT_CLIENT_SECRET: "..."
    REDDIT_USERNAME: "..."
    REDDIT_PASSWORD: "..."
    BLUESKY_IDENTIFIER: "you.bsky.social"
    BLUESKY_PASSWORD: "..."
  subreddits:
    - ClaudeAI
    - LocalLLaMA

Only set credentials for channels you intend to use. LinkedIn, Medium, and Twitter/X return needs_browser with a compose URL — no credentials needed.

MCP tool surface

Eight tools, dot-notation names form a navigable tree (post.*, channel.*, profile.*, subreddit.*). Every tool declares an outputSchema (callers can type-check responses) and MCP annotations (read-only / destructive / idempotent / open-world hints). No LLM calls inside the server.

Tool	Purpose
post_publish	Immediate publish; idempotent on (content.id, channel)
post_schedule	Queue variants for schedule_at, publish the rest immediately
post_drain	Fire all scheduled posts due now — run from cron
post_status	Per-channel state for a content piece or channel
post_unpublish	Best-effort delete (DEV.to sets unpublished; others vary)
channel_hints	Per-channel metadata: char limits, Markdown support, tag vocab
profile_list	Names of configured distribution profiles
subreddit_list	Subreddit Catalog: cooldowns, flair vocab, last-posted

v2.2.0 breaking change. Tools were renamed from flat names (publish, schedule, ...) to dot-notation (post_publish, post_schedule, ...). Update any prompts, agent skills, or n8n nodes that referenced the old names.

Channels

Channel key	Tier	Auth
devto	Auto	DEV_TO_API_KEY
hashnode	Auto	HASHNODE_TOKEN + HASHNODE_PUBLICATION_ID
github_discussions	Auto	GITHUB_TOKEN + GITHUB_DISCUSSION_REPO
reddit	Auto-gated	REDDIT_CLIENT_ID/SECRET/USERNAME/PASSWORD
bluesky	Auto	BLUESKY_IDENTIFIER + BLUESKY_PASSWORD
linkedin	Browser fallback	returns needs_browser + compose URL
medium	Browser fallback	returns needs_browser + compose URL
twitter / x	Browser fallback	returns needs_browser + compose URL
