WordPress MCP Server

WordPress MCP Server

A local Node.js server that exposes WordPress REST API operations for Claude or other MCP-enabled tools.

What this does

• Creates new WordPress blog posts
• Updates existing posts
• Uploads images to WordPress media
• Attaches an uploaded image as a post's featured media

Setup

1. Install dependencies locally if you want to run outside Docker:

npm install

2. Copy the example environment file and configure your WordPress credentials:

cp .env.example .env

3. Fill in .env:

• WP_URL: your self-hosted WordPress base URL, e.g. https://example.com
• WP_USERNAME: WordPress username
• WP_APP_PASSWORD: WordPress application password
• PORT: local port for the MCP server (default 9808)

4. Start the server locally:

npm start

Using Docker

Build and run with Docker Compose:

docker compose up --build

This uses the .env file to provide credentials into the container.

If you want to run only the Docker image:

docker build -t wordpress-mcp .
docker run --env-file .env -p 9808:9808 wordpress-mcp

API Endpoints

• GET /posts
• GET /posts/:postId
• POST /create-post
• POST /update-post
• POST /upload-image
• POST /create-post-with-image
• POST /set-featured-image
• GET /health

Example requests

Create a new post:

curl http://localhost:4000/create-post \
  -H "Content-Type: application/json" \
  -d '{"title":"Hello from Claude","content":"This is a generated blog post.","status":"draft"}'

Upload an image:

curl http://localhost:4000/upload-image \
  -H "Content-Type: application/json" \
  -d '{"imageUrl":"https://example.com/image.jpg","fileName":"image.jpg"}'

Create a post with featured media:

curl http://localhost:4000/create-post-with-image \
  -H "Content-Type: application/json" \
  -d '{"title":"Post with image","content":"Blog content","imageUrl":"https://example.com/image.jpg","fileName":"image.jpg"}'

List posts:

curl http://localhost:4000/posts

Get a specific post:

curl http://localhost:4000/posts/123

Update a post:

curl http://localhost:4000/update-post \
  -H "Content-Type: application/json" \
  -d '{"postId":123,"title":"Updated title","content":"Updated content"}'

Claude / MCP integration

This project includes a manifest at mcp-manifest.json describing the available operations.

The server also exposes the manifest directly at http://localhost:9808/manifest (or your public tunnel host).

Test on Claude

1. Start the server locally or in Docker:

docker compose up -d --build

2. Confirm the manifest is available:

curl http://127.0.0.1:9809/manifest

3. In Claude custom connector / integration settings, use:

• http://localhost:9809 if Claude runs on the same machine
• or your tunnel hostname if using Cloudflare, e.g. https://mcp.yourdomain.com

4. Important: set authentication to No auth / No sign-in service.

This server already authenticates to WordPress using the .env values, so Claude should not be configured with OAuth or an OAuth Client ID.

5. Configure the connector to use the server endpoints:

• GET /health
• GET /manifest
• GET /posts
• GET /posts/:postId
• POST /create-post
• POST /update-post
• POST /upload-image
• POST /set-featured-image
• POST /create-post-with-image
• POST /.well-known/mcp/register (compatibility)
• POST /register (compatibility)

6. Run a quick test request in Claude against /health or /manifest.

Example validation URL

If your connector settings accept a manifest URL, use:

http://localhost:9809/manifest

or:

https://mcp.yourdomain.com/manifest

Note: Keep your .env private. The server must authenticate to WordPress using an Application Password and the correct site URL.
