SharpLens

SharpLens runs locally from a Node.js package published to the npm registry: sharplens-mcp version 1.5.3. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs Node.js; clients usually start it with npx — the usual command is npx -y sharplens-mcp@1.5.3. It reads these environment variables: DOTNET_SOLUTION_PATH, ROSLYN_LOG_LEVEL and ROSLYN_TIMEOUT_SECONDS; set them in the client's configuration for this server.

SharpLens runs locally from a .NET package published to NuGet: SharpLensMcp version 1.5.3. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs the .NET SDK; run as a .NET tool; the entry names dotnet tool run as the runtime. It reads these environment variables: DOTNET_SOLUTION_PATH, ROSLYN_LOG_LEVEL and ROSLYN_TIMEOUT_SECONDS; set them in the client's configuration for this server.

In the mcpServers JSON format that many desktop and editor MCP clients read, the entry looks like this (placeholders in angle brackets):

{
  "mcpServers": {
    "sharplens": {
      "command": "npx",
      "args": [
        "-y",
        "sharplens-mcp@1.5.3"
      ],
      "env": {
        "DOTNET_SOLUTION_PATH": "<value>",
        "ROSLYN_LOG_LEVEL": "<value>",
        "ROSLYN_TIMEOUT_SECONDS": "<value>"
      }
    }
  }
}
