WikiJS MCP Server

A Model Context Protocol (MCP) server for managing WikiJS instances. This server provides read and write capabilities for wiki pages, including search, creation, updates, deletion, and knowledge graph exploration.

Important: This is an MCP server without OAuth authentication, designed for trusted environments where the server runs with pre-configured API credentials.

4. Run locally:

npm run dev

Deploy to Cloudflare Workers

1. Click the deploy button above or run:

npm run deploy

2. Set your secrets:

npx wrangler secret put WIKI_JS_BASE_URL
npx wrangler secret put WIKI_JS_API_KEY

Configuration

Environment Variables

Path Format

Page paths are automatically normalized:

• Input: my-page, /my-page, //my-page/, my-page/

• Normalized: /my-page

      }
    }
  }
}

Security Considerations

This MCP server runs without OAuth and uses pre-configured API credentials. Ensure:

1. API Key Security: Store WIKI_JS_API_KEY as a Cloudflare secret, never commit it to code

2. Access Control: The API key inherits permissions from the WikiJS user account it belongs to

3. Network Security: Deploy with HTTPS only (enforced by Cloudflare Workers)

4. Logging: API keys are never logged; only hasApiKey: true/false is tracked

API Reference

WikiJS GraphQL API

This server uses the WikiJS GraphQL API. Key mutations used:

Create Page:

mutation {
  pages {
    create(
      title: String!
      path: String!
      content: String!
      editor: "markdown"
      isPublished: true
      isPrivate: false
      locale: "en"
      description: String!
      tags: [String]!
    ) {
      responseResult { succeeded message }
      page { id path title }
    }
  }
}

Update Page:

mutation {
  pages {
    update(
      id: Int!
      title: String
      content: String
      description: String
      tags: [String]
    ) {
      responseResult { succeeded message }
    }
  }
}

Delete Page:

mutation {
  pages {
    delete(id: Int!) {
      responseResult { succeeded message }
    }
  }
}

Troubleshooting

Common Issues

1. 400 Bad Request on Create: Ensure your WikiJS API key has write permissions

2. Page Not Found: Paths are case-sensitive; check the exact path in WikiJS

3. Rate Limiting: Large wikis may hit GraphQL complexity limits; use pagination

Debug Logging

Enable debug logging in development:

LOG_LEVEL=debug npm run dev

Customizing your MCP Server

To add your own tools to the MCP server, define each tool inside the init() method of src/index.ts using this.server.tool(...).

Connect to Cloudflare AI Playground

You can connect to your MCP server from the Cloudflare AI Playground, which is a remote MCP client:

1. Go to https://playground.ai.cloudflare.com/

2. Enter your deployed MCP server URL (remote-mcp-server-authless.<your-account>.workers.dev/mcp)

3. You can now use your MCP tools directly from the playground!

Connect Claude Desktop to your MCP server

You can also connect to your remote MCP server from local MCP clients, by using the mcp-remote proxy.

To connect to your MCP server from Claude Desktop, follow Anthropic's Quickstart and within Claude Desktop go to Settings > Developer > Edit Config.

Update with this configuration:

{
	"mcpServers": {
		"calculator": {
			"command": "npx",
			"args": [
				"mcp-remote",
				"http://wiki-mcp.your-account.workers.dev/mcp"
			]
		}
	}
}

Restart Claude and you should see the tools become available.
