How to Set Up and Use Nia
Nia is a context-augmentation MCP server designed to give AI coding agents access to an always-up-to-date knowledge base covering packages, documentation, and codebases — reportedly improving agent task performance by 27%. It connects to the Nia platform at app.trynia.ai and exposes semantic search across 150M+ pre-indexed documents from PyPI, NPM, Crates.io, Go modules, and more, as well as deep GitHub code search and autonomous document research capabilities. Developers use it to ensure their AI assistant always has current API references and package documentation rather than relying on potentially stale training data.
Prerequisites
- Node.js 18+ or a compatible JavaScript runtime (Bun, pnpm, or Yarn also supported)
- A free or paid Nia account at app.trynia.ai — the setup wizard handles account creation
- An MCP-compatible AI client: Cursor, VS Code with Copilot, Claude Desktop, Claude Code, or Windsurf
- Internet access so the server can reach the Nia cloud API
Run the Nia setup wizard
The fastest way to set up Nia is via the interactive wizard, which creates your account, generates an API key, and automatically configures your IDE or AI client — supporting 30+ agents.
npx nia-wizard@latest
# Alternative runtimes:
pnpx nia-wizard@latest
bunx nia-wizard@latest
yarn dlx nia-wizard@latestObtain your Nia API key
If you skip the wizard or need to reconfigure, visit app.trynia.ai, sign in, and retrieve your API key from the dashboard. You will need this key for manual MCP configuration.
Configure your MCP client manually
Add Nia to your MCP client configuration file using npx. Replace `your-api-key-here` with the key obtained from app.trynia.ai.
{
"mcpServers": {
"nia": {
"command": "npx",
"args": ["-y", "nia"],
"env": {
"NIA_API_KEY": "your-api-key-here"
}
}
}
}Index your own codebase or documentation
After setup, you can index local folders or online documentation so Nia includes your proprietary code in its search results. Use the index function in the Nia dashboard or via agent prompts.
# Prompt your agent:
# "Index the folder at /path/to/my/project using Nia"
# Or via dashboard: visit app.trynia.ai > Sources > Add SourceVerify the integration
Ask your AI assistant a question about a recent package or API. Nia should return citations from up-to-date sources rather than relying on training data alone.

Use Nia-powered search to get accurate, up-to-date answers about libraries, packages, and codebases.
- "Search Nia for the latest React 19 concurrent features and show me the API docs"
- "Use Nia to find examples of using the Rust tokio crate for async file I/O"
- "Look up the current LangChain Python API for building RAG pipelines"
- "Search NPM package documentation for the zod v3 schema validation API"Troubleshooting Nia
The wizard fails to configure my IDE automatically
Run the wizard with your specific client flag (e.g., `npx nia-wizard@latest --client cursor`) or manually add the MCP JSON block to your client's configuration file using the API key from app.trynia.ai.
Search results are outdated or missing a package I need
Nia indexes 150M+ documents automatically, but niche packages may not be included. Use the Sources section in the app.trynia.ai dashboard to manually add a specific package URL or GitHub repository for indexing.
The MCP server starts but the agent does not use Nia tools
Explicitly instruct your agent to use Nia by prefixing your request with phrases like 'Using Nia, search for...' or check that the MCP server shows as connected in your client's MCP server list.
