2. Clone or Download the Repository: Choose any workspace where files can be accessed without path conflicts.

3. Run npm install: Navigate to the project directory and execute this command in your terminal.

   npm i
   

4. Configure MCP Server Parameters: Update the environment variables in your claude_desktop_config.json file:

   {
     "mcpServers": {
       "kintone": {
         "command": "node",
         "env": {
           "KINTONE_DOMAIN": "[your-subdomain].cybozu.com",
           "KINTONE_USERNAME": "MCP connection username for kintone",
           "KINTONE_PASSWORD": "plain-text password of a valid Kintone user"
         },
         "args": [
           "[path-to-your-kintone-mcp-server]/server.js"
         ]
       }
     }
   }
   

5. Restart the Claude Desktop Application: After updating, restart the CLI to ensure changes take effect.

💡 Key Use Cases in AI Workflows

Scenario 1: Customizing User Data Access

Suppose you work with a sales team and want them to access updated customer data directly in their CRM system—Kintone. Using this server, an AI application like Claude can fetch dynamic updates, enriching user experience and enabling real-time interactions.

Implementation: Utilize the get_records capability to retrieve up-to-date information and present it via prompts or commands to users.

Scenario 2: Automating Forms with User Inputs

For frequent form submissions from multiple sources, this server allows capturing data directly into Kintone while ensuring accuracy and consistency across all entries.

Implementation: Leverage the create_record function whenever new data arrives from various input sources, automating the intake process.

🔌 Integration with MCP Clients

This section specifically documents how different MCP clients interact with the Kintone server for specific functionalities:

1. Resource Management

With support for managing resources via the MCP protocol, developers can easily integrate their applications to update or delete records programmatically.

2. Tool Utilization & Field Enhancements

Developers can enrich existing kintone apps by adding new fields dynamically using API calls facilitated through this server.

📊 Performance & Compatibility Matrix

The Kintone MCP server is designed for smooth operation across a wide range of environments and data handling scenarios, ensuring reliable and timely responses to requests from various AI tools.

Advanced Configuration & Security

Custom configurations can be applied by setting environment variables as needed. For security, it's critical to manage API key distribution carefully.

❓ Frequently Asked Questions (FAQ)

1. Why does the server restrict uploads over 1MB?
   • Currently, limitations on file size are due to backend system constraints. Future updates might address this constraint.
2. Can I connect multiple applications simultaneously?
   • Absolutely! The server supports connecting up to three different MCPS servers (like kintone and other platforms) concurrently.
3. Is support available for advanced security features like two-factor authentication?
   • Basic authentication is supported, but advanced features such as 2FA need to be configured separately within the kintone platform.
4. What should I do if my records exceed the query limit in Kintone?
   • Use paging methods provided by the API for handling large datasets iteratively.
5. How can I ensure data privacy when connecting applications externally?
   • Regularly update your credentials and utilize secure network connections to maintain data integrity.
