How do I install the onyx mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `GITHUB_TOKEN` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the Onyx MCP Server?

Model Context Protocol (MCP) server for Onyx programming language with documentation, GitHub examples, and bridge connectivity

The short version

A Model Context Protocol (MCP) server providing search and query access to Onyx programming language documentation and GitHub code examples. The server includes comprehensive crawling capabilities to populate data, but crawling is NOT accessible through the MCP interface - ensuring clean separation between data collection and query functionality.

What it needs from you

Onyx compiler must be installed and available in PATH - Install from: https://onyxlang.io/ - The tool executes code in a sandboxed temporary directory - Default timeout of 10 seconds (configurable) prevents infinite loops
