OpenApi MCP

MCP server for loading and exploring OpenAPI/Swagger specifications. Lets AI assistants browse API contracts dynamically — load any OpenAPI spec, search endpoints, inspect schemas, and retrieve operations — without needing the spec in-context.

Usage

Manually

Add to your MCP client config:

{
  "mcpServers": {
    "openapi-mcp": {
      "command": "npx",
      "args": ["-y", "@ceski23/openapi-mcp"]
    }
  }
}

Via AI agent

Ask your AI assistant to add it:

Add the MCP server @ceski23/openapi-mcp to my config. Run it with npx -y @ceski23/openapi-mcp via stdio.

Most assistants can modify your MCP config file directly.
