CSharpMCP MCP Server 工具

Execute the provided C# code, and the state (like variables) will be preserved each time.

Clean the code execution context, all states will be cleared.

Get the history code.

概览

What is CSharpMCP?

CSharpMCP is a Model Context Protocol (MCP) server for executing C# code using the Roslyn compiler. It is intended for developers who need to run C# snippets programmatically, with state persistence across executions.

How to use CSharpMCP?

To use CSharpMCP, configure it as an MCP server in your MCP client application. To reference existing projects, compile the project and pass the path of the resulting DLL as a startup parameter; the server will add those assemblies as references. Invoke the provided tools (RunAsync, CleanExecuteContext, GetHistoryCode) from your MCP client.

Key features of CSharpMCP

Execute C# code snippets with Roslyn
State (variables) preserved across calls
Clear execution context and reset state
Retrieve previously executed code history
Support for referencing external compiled DLLs

Use cases of CSharpMCP

Running C# scripts interactively within an MCP-aware environment
Prototyping C# logic without creating a full project
Testing small code fragments with persistent state
Integrating C# code execution into AI-assisted coding workflows

常见问题

What does RunAsync do?

RunAsync executes the provided C# code and preserves the state (variables) between calls, allowing incremental code execution.

How do I clean the execution state?

Use the CleanExecuteContext tool to clear all state and reset the execution context.

Can I use existing C# libraries?

Yes. Compile the project to a DLL, then pass that DLL path as a startup parameter when launching CSharpMCP.

What are the security implications?

This server executes arbitrary C# code on the local machine. Use with caution and only in trusted environments.

How do I retrieve previously executed code?

Use the GetHistoryCode tool to retrieve the full history of code that has been executed.
