Add MCP Protocol Compliance Check for Installed Packages

[crazyyanchao]

Description:

In the current implementation, there is no check to verify whether the installed packages (via uvx or npm) comply with the MCP protocol. This can lead to non-MCP-compliant packages being installed and configured in the claude_desktop_config.json file, which is not ideal for maintaining compatibility and consistency within the MCP ecosystem.

Problem:

• When installing MCP servers using npx or uvx, there is no validation to ensure that the installed package adheres to the MCP protocol.
• As a result, non-MCP-compliant packages could be installed, and their configurations would be added to claude_desktop_config.json, potentially leading to issues when trying to interact with these packages via MCP-compliant tools.

Proposed Solution:

• Implement MCP Compliance Check: Before adding a package to the claude_desktop_config.json file, check whether it is MCP-compliant. This could be done by:

  1. Verifying the package’s package.json or other metadata to ensure it includes the necessary fields or properties that indicate MCP protocol compliance.
  2. Adding a method that checks the package for required MCP properties, such as the correct schema for tool interaction.

• Error Handling: If a non-compliant package is detected, log an error and prevent it from being added to the configuration file, while providing feedback to the user.

Benefits:

• Ensures only MCP-compliant packages are installed and configured, improving stability and consistency in the MCP ecosystem.
• Prevents the accidental installation of incompatible tools that may break MCP-based interactions.

Additional Information:

• The MCP protocol defines specific requirements for tool interactions and metadata structure, so validating packages before installation is crucial for maintaining the integrity of the system.
• This change will require checking the package metadata (such as package.json or specific file formats) for compliance with MCP standards.
