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 |

Example agent call

// post_publish tool
{
  "content": {
    "id": "n8n-webhook-setup@2026-05-20",
    "title": "How to set up an n8n webhook",
    "body_md": "...",
    "tags": ["automation", "n8n", "tutorial"],
    "canonical_url": "https://yourblog.com/n8n-webhook-setup",
    "author": "You"
  },
  "variants": [
    {
      "channel": "devto:main",
      "title": "How to set up an n8n webhook",
      "body": "...",
      "tags": ["automation", "n8n", "tutorial", "devops"],
      "canonical_url": "https://yourblog.com/n8n-webhook-setup",
      "extras": {}
    },
    {
      "channel": "reddit:ClaudeAI",
      "title": "Built a webhook automation with n8n",
      "body": "Here's how I set it up...",
      "tags": [],
      "extras": { "flair": "Project" }
    }
  ],
  "profile_name": "default"
}

Idempotency

Re-running post_publish with the same content.id + channel pair returns the existing live_url immediately without making another platform API call. Safe to retry on failure.

Scheduling

Variants with schedule_at (ISO-8601 with timezone, e.g. "2026-05-21T09:00:00+00:00") are stored in ~/.distribution-mcp/scheduled.yaml and fired on the next post_drain call. Run drain from cron:

# fire due posts every 5 minutes
*/5 * * * * npx -y content-distribution-mcp drain

Or call the post_drain MCP tool directly from an agent.

Environment variables

| Variable | Default | Purpose | |---|---|---| | DISTRIBUTION_BACKEND | yaml | State backend (yaml only in v1) | | DISTRIBUTION_BACKEND_DIR | ~/.distribution-mcp | Directory for YAML state files |

Requirements

• Node.js 18 or later
