Description

Issue Description

The MCP server repeatedly crashes when executing Tinker commands, requiring manual restarts. The server consistently hits the 30-second PHP execution timeout limit and terminates with exit code 255.

The tinker command Sonnet is trying to execute is including various things like clearing the cache, creating a job, using a service to upload data, etc. So it takes some time to complete.

Expected Behavior

The MCP server should handle Tinker commands without timing out and maintain a stable connection for extended development sessions.

Suggested Solutions

I probably could update the PHP execution time locally, but I feel that this is something the user shouldnt worry about and could be done by boost. --> Increase PHP execution timeout: Configure max_execution_time or use set_time_limit(0) for the MCP server process

Steps To Reproduce

Actual Behavior

• Server starts successfully and discovers the tools
• After approximately 30 seconds of operation, the server crashes with a fatal PHP timeout error
• The process exits with code 255
• Manual restart is required to restore functionality
• This pattern repeats consistently
