Strapi MCP

An MCP server for Strapi CMS, providing access to content types and entries through the Model Context Protocol.

Overview

This MCP server integrates with any Strapi CMS instance to provide:
- Access to Strapi content types as resources
- Tools to create and update content types in Strapi
- Tools to manage content entries (create, read, update, delete)
- Support for Strapi in development mode
- Robust error handling with clear diagnostics and troubleshooting guidance
- Configuration validation to prevent common setup issues

Setup

### Environment Variables

It's recommended to use a .env file in the project root to store your credentials.

- STRAPI_URL: The URL of your Strapi instance (default: http://localhost:1337)
- STRAPI_ADMIN_EMAIL: The email address for a Strapi admin user (Recommended for full functionality, especially schema access).
- STRAPI_ADMIN_PASSWORD: The password for the Strapi admin user (Recommended).
- STRAPI_API_TOKEN: (Optional Fallback) An API token. Can be used if admin credentials are not provided, but may have limited permissions.
- STRAPI_DEV_MODE: Set to "true" to enable development mode features (defaults to false).

Example .env file:
``dotenv
STRAPI_URL=http://localhost:1337
STRAPI_ADMIN_EMAIL=your_admin_email@example.com
STRAPI_ADMIN_PASSWORD=your_admin_password
# STRAPI_API_TOKEN=your_api_token_here # Optional
`
Important:
- Add .env to your .gitignore file to avoid committing credentials
- Avoid placeholder values like "strapi_token" - the server validates and rejects common placeholders

### Installation

#### Install from npm (Recommended)
`bash
npm install strapi-mcp
`

#### Install from source (Development)
For the latest development features:
`bash
git clone https://github.com/l33tdawg/strapi-mcp.git
cd strapi-mcp
npm install
npm run build
`

### Running

Recommended Method (using Cursor MCP Configuration):

For Cursor users, configure the strapi-mcp server in your ~/.cursor/mcp.json file:

`json
"strapi-mcp": {
"command": "npx",
"args": ["strapi-mcp"],
"env": {
"STRAPI_URL": "http://localhost:1337",
"STRAPI_ADMIN_EMAIL": "your_admin_email@example.com",
"STRAPI_ADMIN_PASSWORD": "your_admin_password"
}
}
`

If you installed from source, use the direct path instead:
`json
"strapi-mcp": {
"command": "node",
"args": ["/path/to/strapi-mcp/build/index.js"],
"env": {
"STRAPI_URL": "http://localhost:1337",
"STRAPI_ADMIN_EMAIL": "your_admin_email@example.com",
"STRAPI_ADMIN_PASSWORD": "your_admin_password"
}
}
`

Cursor will manage the server lifecycle automatically when strapi-mcp tools are used.

Alternative Method (using .env file):

Make sure you have built the project (npm run build). Then run the server using Node.js v20.6.0+ with the --env-file flag:

`bash
node --env-file=.env build/index.js
`

Alternative (using environment variables directly):

`bash
export STRAPI_URL=http://localhost:1337
export STRAPI_ADMIN_EMAIL=your_admin_email@example.com
export STRAPI_ADMIN_PASSWORD=your_admin_password


export STRAPI_API_TOKEN=your-api-token # Optional fallback

export STRAPI_DEV_MODE=true # optional

Run the globally installed package (if installed via npm install -g)

strapi-mcp

Or run the local build directly

node build/index.js
`

### Advanced Features

#### Filtering, Pagination, and Sorting
The get_entries tool supports advanced query options:
`json
{
"contentType": "api::article.article",
"filters": {
"title": {
"$contains": "hello"
}
},
"pagination": {
"page": 1,
"pageSize": 10
},
"sort": ["title:asc", "createdAt:desc"],
"populate": ["author", "categories"]
}
`

#### Resource URIs
Resources can be accessed with various URI formats:
- strapi://content-type/api::article.article - Get all articles
- strapi://content-type/api::article.article/1 - Get article with ID 1
- strapi://content-type/api::article.article?filters={"title":{"$contains":"hello"}} - Get filtered articles

$3

The publish_entry and unpublish_entry tools provide control over the content lifecycle:

`json
{
"contentType": "api::article.article",
"id": "1"
}
`

These tools utilize the admin API paths for publishing/unpublishing actions, with a fallback to directly updating the publishedAt field if admin permissions are not available.

$3

Strapi components can be managed with the following tools:

- list_components: Get all available components
- get_component_schema: View a specific component's structure
- create_component: Create a new component with specified fields
- update_component: Modify an existing component

Example of creating a component:

`json
{
"componentData": {
"displayName": "Security Settings",
"category": "security",
"icon": "shield",
"attributes": {
"enableTwoFactor": {
"type": "boolean",
"default": false
},
"passwordExpiration": {
"type": "integer",
"min": 0
}
}
}
}
`

Development

Install dependencies:
`bash
npm install
`

Build the server:
`bash
npm run build
`

For development with auto-rebuild:
`bash
npm run watch
`

Installation

For detailed step-by-step instructions on how to deploy and test this MCP server, please see the DEPLOYMENT.md file.

Quick setup:

1. Build the server: npm run build
2. Configure your Strapi instance and get an API token
3. Add the server config to Claude Desktop:

On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json
On Windows: %APPDATA%/Claude/claude_desktop_config.json

`json
{
"mcpServers": {
"strapi-mcp": {
"command": "npx",
"args": ["strapi-mcp"],
"env": {
"STRAPI_URL": "http://localhost:1337",
"STRAPI_ADMIN_EMAIL": "your_admin_email@example.com",
"STRAPI_ADMIN_PASSWORD": "your_admin_password"
}
}
}
}
`

If you installed from source, use the direct path:
`json
{
"mcpServers": {
"strapi-mcp": {
"command": "/path/to/strapi-mcp/build/index.js",
"env": {
"STRAPI_URL": "http://localhost:1337",
"STRAPI_ADMIN_EMAIL": "your_admin_email@example.com",
"STRAPI_ADMIN_PASSWORD": "your_admin_password"
}
}
}
}
`

$3

- STRAPI_URL (optional): The URL of your Strapi instance (defaults to http://localhost:1337)
- STRAPI_ADMIN_EMAIL & STRAPI_ADMIN_PASSWORD (Recommended): Credentials for a Strapi admin user. Required for full functionality like fetching content type schemas.
- STRAPI_API_TOKEN (Optional Fallback): Your Strapi API token. Can be used if admin credentials are not provided, but functionality might be limited based on token permissions.
- STRAPI_DEV_MODE (optional): Set to "true" to enable development mode features (defaults to false)

### Authentication Priority

The server prioritizes authentication methods in this order:
1. Admin Email & Password (STRAPI_ADMIN_EMAIL, STRAPI_ADMIN_PASSWORD)
2. API Token (STRAPI_API_TOKEN)

It's strongly recommended to use Admin Credentials for the best results.

### Getting Strapi Credentials

- Admin Credentials: Use the email and password of an existing Super Admin or create a dedicated admin user in your Strapi admin panel (Settings > Administration Panel > Users).
- API Token: (Optional Fallback)

1. Log in to your Strapi admin panel
2. Go to Settings > API Tokens
3. Click "Create new API Token"
4. Set a name, description, and token type (preferably "Full access")
5. Copy the generated token and use it in your MCP server configuration

$3

Common Issues and Solutions:

#### 1. Placeholder API Token Error
`
[Error] STRAPI_API_TOKEN appears to be a placeholder value...
`
Solution: Replace "strapi_token" or "your-api-token-here" with a real API token from your Strapi admin panel.

#### 2. Connection Refused Error
`
Cannot connect to Strapi instance: Connection refused. Is Strapi running at http://localhost:1337?
`
Solution:
- Ensure Strapi is running: npm run develop or yarn develop
- Check if the URL in STRAPI_URL is correct
- Verify your database (MySQL/PostgreSQL) is running

#### 3. Authentication Failed
`
Cannot connect to Strapi instance: Authentication failed. Check your API token or admin credentials.
`
Solution:
- Verify your API token has proper permissions (preferably "Full access")
- Check admin email/password are correct
- Ensure the admin user exists and is active

#### 4. Context Window Overflow with File Uploads
`
Error: Context window overflow due to large base64 strings
`
Problem: Base64 encoded files can be extremely large (even small images can be 50-100KB of text), causing context window overflow.

Solutions:
- Use upload_media_from_path instead of upload_media for files larger than ~500KB
- Reduce file sizes before uploading (compress images, reduce resolution)
- Use smaller files - the upload_media tool has a 1MB base64 limit (~750KB file)

#### 5. Fake Content Types (api::data.data, api::error.error)
This issue has been fixed in v0.1.8. If you still see these, you may be using an older version.

#### 6. Empty Results vs Errors
As of v0.1.8, the server now clearly distinguishes between:
- Empty collections (content type exists but has no entries) → Returns {"data": [], "meta": {...}}
- Actual errors (content type doesn't exist, auth failed, etc.) → Throws descriptive error with troubleshooting steps

#### 7. Permission Errors
`
Access forbidden. Your API token may lack necessary permissions.
`
Solution:
- Use admin credentials instead of API token for full functionality
- If using API token, ensure it has "Full access" permissions
- Check that the content type allows public access if using limited API token

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

`bash
npm run inspector
`

The Inspector will provide a URL to access debugging tools in your browser.
