What does the csharp LSP plugin do?

It connects an AI agent to a C# language server, giving it code intelligence so it can navigate and analyze C# projects accurately rather than relying only on reading raw source files.

Do I need a C# project to use it?

Yes, it is meant for working with C# codebases, where the language server provides the symbol and structure information the agent uses.

Is this a standalone tool or a plugin?

It is a plugin. It is added to an agent's configuration and extends the agent with C# code intelligence capabilities.

csharp-lsp

PackAI & models

csharp-lsp is a plugin that gives an AI agent C# code intelligence through the csharp LSP Claude plugin. It connects the agent to a C# language server so it can navigate and analyze C# projects accurately instead of guessing from raw file text. This helps when working with large codebases where understanding types, symbols, and structure matters.

Unavailable. A Claude Code plugin. It installs in Claude Code, and ahel does not serve packs through its connector yet.

In Claude Code, run:

/plugin install csharp-lsp@claude-plugins-official

It installs from Anthropic's official plugin marketplace.

What your AI can do with it

Runs a C# language server that the agent can query for code intelligence
Lets the agent navigate C# projects by symbols and definitions
Supports accurate analysis of C# code structure and types
Works as a plugin added to an agent's setup

Getting started

Have a C# project you want the agent to work on.
Add the csharp-lsp plugin to your agent's plugin configuration.
Start a session and ask the agent to navigate or analyze the C# code; it will use the language server for code intelligence.
