About CSharpMCP
CSharpMCP is a Roslyn-based MCP server for executing C# snippets. It preserves execution state between runs and can reference compiled project DLLs.
Key features
- 01Execute C# snippets
- 02Preserve state between runs
- 03Clear execution context
- 04View code execution history
- 05Reference compiled project DLLs
Use cases
- 01Run C# snippets with shared state
- 02Execute snippets against compiled project assemblies
MCP support
Exposes tools to MCP clients for running C# code, clearing execution state, and retrieving code history. Code runs on the local machine.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
