└ [Error] MCP config is not a valid JSON

TL;DR

The issue is likely due to an invalid JSON format in the .mcp.json file, and fixing the JSON syntax may resolve the problem.

Guidance

• Verify that the .mcp.json file is properly formatted as JSON, checking for any syntax errors such as missing or mismatched brackets, quotes, or commas.
• Open the .mcp.json file in a text editor or a JSON validator to identify and correct any formatting issues.
• Check for any invisible characters or encoding issues that might be causing the JSON parsing to fail.

Example

No specific code example can be provided without the actual contents of the .mcp.json file, but a simple JSON validation tool or a text editor with JSON syntax highlighting can help identify formatting issues.

Notes

The exact solution depends on the specific contents and formatting of the .mcp.json file, which is not provided in the issue description.

Recommendation

Apply workaround: Manually inspect and correct the JSON formatting in the .mcp.json file, as this is the most direct approach to resolving the parsing error described.
