Nia Codebase MCP

The Nia Codebase MCP server allows you to integrate with Nia's codebase understanding capabilities through function calling in tools like Cursor, Claude Desktop, and other MCP-compatible clients.

Installation

You can use this MCP server without installing it using npx:

npx -y nia-codebase-mcp@1.0.1 --api-key=YOUR_NIA_API_KEY --transport=stdio

Transport Options

The Nia Codebase MCP server supports two transport methods:

1. Standard Input/Output (stdio) - Default

This is the default transport method and is used when no transport is specified:

npx -y nia-codebase-mcp --api-key=YOUR_NIA_API_KEY

2. Server-Sent Events (SSE)

To use SSE transport, specify the --transport=sse flag and optionally a port (default is 3000):

npx -y nia-codebase-mcp --api-key=YOUR_NIA_API_KEY --transport=sse --port=3000

Usage in MCP Clients

Cursor

1. Open Cursor Settings > Features > MCP Servers
2. Add a new MCP server
3. Name: nia-codebase
4. Type: command
5. Command: npx -y nia-codebase-mcp@1.0.1 --api-key=YOUR_NIA_API_KEY

Claude Desktop

Add to your Claude Desktop configuration at ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "nia-codebase": {
      "command": "npx",
      "args": ["-y", "nia-codebase-mcp@1.0.1", "--api-key=YOUR_NIA_API_KEY"]
    }
  }
}

For Windows users, the configuration is at %APPDATA%\Claude\claude_desktop_config.json.

Example Prompts

Using the lookup_codebase_context tool, please analyze my project structure and tell me what the main components are.

Using the lookup_codebase_context tool, search the codebase to understand how the authentication system works and explain its key components.

Debugging

If the server isn't working properly, you can enable debug mode:

npx -y nia-codebase-mcp@1.0.1 --api-key=YOUR_NIA_API_KEY --debug=true

Environment Variables

You can also configure the server using environment variables:

• NIA_API_KEY: Your Nia API key
• TRANSPORT: The transport method to use (stdio or sse)
• PORT: The port to use for SSE transport (default: 3000)
• TOOL_TIMEOUT_MS: Custom timeout for tool execution (default: 300000ms)
• DEBUG: Enable debug mode (true or false)

Tools

This MCP server provides the following tool:

• lookup_codebase_context: Look up context from a codebase indexed in Nia, retrieving relevant code snippets based on user queries.

Requirements

• Node.js 18 or higher
• A valid Nia API key
• A codebase indexed in Nia
