Questions

What is the serena plugin?

It is a plugin that provides a semantic code analysis MCP server, letting an AI agent understand, navigate, and suggest changes to a codebase through language server protocol integration.

How does serena understand my code?

It integrates with language servers via the language server protocol, which gives it semantic understanding of code structure rather than reading files as plain text.

Which languages does serena support?

The item description does not list specific languages; support depends on the language server protocol integration.

Can serena edit my code directly?

It provides refactoring suggestions and codebase navigation; the description does not state that it applies edits on its own.
