Clarification on Usage of .env Files in Different Directories

[suzuki-shm]

Hello everyone,

I need some clarification regarding the usage of .env files in different directories within our project. Here are the points I'm confused about the difference between repo_dir/.env and repo_dir/agent_dir/.env.

The Quickstart guide instructs to create and place the .env file inside the agent_dir.
On the other hand, the documentation for tools/mcp-tools advises placing the .env file in reppo_dir.

Should we consolidate the .env files into one location, or should they be used separately for different purposes? Any guidance on this matter would be greatly appreciated.

Thank you!

Sorry, I resolved it myself. The repository structure is introduced in more detail at this link. It seems that for MCP introductions, we should follow this structure.
