PostKing MCP Server

The official Model Context Protocol server for PostKing — an AI-powered content platform for social media scheduling, blog publishing, and brand management.

Connect Claude (Desktop, Cursor, or any MCP client) to your PostKing account and manage your entire content operation through conversation — generate posts, schedule them, repurpose URLs into social content, write and publish blog articles, generate landing pages and side pages, run SEO / GEO research and drafting, manage your asset library and weekly posting schedule, handle domains and API keys, and more.

The server exposes 210 tools across 26 modules — full parity with the postking-cli.

Transport note: On the remote HTTP transport (mcp.postking.app), 206 tools are available. The 4 authentication tools (login_start, login_complete, logout, whoami) are omitted on that transport because it uses OAuth bearer tokens rather than device-code login. All other 206 tools are identical across both transports.

Quick start

Claude Desktop

Option A — Via the GUI:

1. Open Claude Desktop → Settings (gear icon) → Developer → Edit Config
2. This opens claude_desktop_config.json in your default editor
3. Paste the following and save:

{
  "mcpServers": {
    "postking": {
      "command": "npx",
      "args": ["-y", "postking-mcp"]
    }
  }
}

4. Restart Claude Desktop

Option B — Edit the config file directly:

Open ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows) in any text editor, paste the same JSON above, and save.

Once restarted, tell Claude: "Login to PostKing"

Claude Code (CLI)

claude mcp add postking -- npx -y postking-mcp

Hermes

npm i -g postking-mcp
hermes mcp add postking --command postking-mcp

Then in Hermes: "Login to PostKing".

Cursor / other MCP clients

Use the same npx -y postking-mcp command in your client's MCP server config.

Login flow

No API keys to copy. PostKing uses a device login flow:

1. Tell Claude: "Login to PostKing"
2. Claude calls login_start → shows a URL and short code
3. Visit the URL in your browser, log in, approve
4. Tell Claude: "Done"
5. Claude calls login_complete → saves your token to ~/.postking/credentials.json

You never need to log in again. The token is permanent.

What you can do

Authentication

Available on stdio/local transport only. Remote HTTP transport authenticates via OAuth bearer token before the session is created.

Brands

Content themes

Social posts

Repurpose

Voice profiles

Social accounts

Reddit

Reddit is a repurpose-to-Reddit workflow, not a scheduled publishing medium. Flow: reddit_generate_pool → reddit_get_pool → reddit_suggest → reddit_rewrite → reddit_list_posts.

Blog

SEO / GEO

Canonical flow: seo_add_seeds → seo_generate_keywords → seo_categorize → seo_generate_clusters → approve clusters → seo_generate_roadmap → review briefs → seo_approve_briefs (auto-fires article generation) → poll get_job → audit & publish.
