Installation

This tool is still in development and we havn't pushed to the npm repository. You need to clone this repository on your local then build npm run build

To use with Claude Desktop, add the server config:

On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json On Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "seq": {
      "command":"node",
      "args": ["/Users/ahmadreza/source/ahmad2x4/mcp-server-seq/build/seq-server.js"],
      "env": {
        "SEQ_BASE_URL": "your-seq-url",
        "SEQ_API_KEY": "your-api-key"
      }
    }
  }
}

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. The server implements proper error handling and logging for all operations. You can run the test script to verify functionality:

npm run test-script

Type Safety

The server implements comprehensive type safety using:

• TypeScript for static type checking
• Zod schema validation for runtime type checking
• Proper error handling and response formatting =======
