OpenAPI APIs for Grok

io.github.alyiox/mcp-openapix

MCP server that fronts any OpenAPI service: discover operations from its spec and call them

client:Grok transport:stdio runtime:pypi

Install OpenAPI APIs in Grok

.mcp.json (in your project root)

{
  "mcpServers": {
    "mcp-openapix": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "mcp-openapix"
      ]
    }
  }
}

Grok Build reads Claude Code's .mcp.json and Claude Desktop's config unchanged, so a server you have already set up there needs nothing new. The Grok web app and X integration do not take custom servers. Grok docs
