This PR fixes issue mudler#20 - Interactive commands causing MCP shell to stall indefinitely.

Changes

  • Add syscall.Setpgid to create new process group for proper child process cleanup
  • Add detectInteractiveCommands function to warn about potentially interactive commands
  • Add process group kill on timeout to ensure all child processes are terminated
  • Update description to reflect new capabilities

Testing

The fix ensures that:

  1. Interactive commands are detected and logged as warnings
  2. Process groups are properly managed for cleanup
  3. Timeout enforcement works correctly by killing entire process groups

Fixes: mudler#20

* feat(localrecall): gate all log messages under DEBUG flag

- Add debugMode boolean that reads from DEBUG environment variable
- Create debugLog() helper function that only prints when DEBUG=1
- Replace all log.Printf/log.Println calls with debugLog()
- By default, no logs are emitted to preserve JSON-RPC stdio protocol

Fixes: The LocalRecall MCP was corrupting JSON-RPC communication by
emitting logs to stdout, causing the container to fail. Logs are now
only shown when DEBUG=1 is set.
* feat: add codemogger MCP server

- Add Dockerfile for codemogger (Node.js based MCP server)
- Add codemogger to GitHub Actions CI pipeline

* fix: remove redundant npm install -g npx (npx is included in node:20-slim)

* docs: add codemogger to README
- Add getTimeout() function to read SHELL_TIMEOUT env var (default: 30s)
- Update ExecuteCommand to use getTimeout() instead of hardcoded value
- Update tool description to document the new env variable
…or shell MCP

- Add syscall.Setpgid to create new process group for proper child process cleanup
- Add detectInteractiveCommands function to warn about potentially interactive commands
- Add process group kill on timeout to ensure all child processes are terminated
- Update description to reflect new capabilities
