MCP Server for OpenAPI
OpenAPI MCP Server
An OpenAPI MCP server turns an API specification into a ready-to-use MCP toolset for AI assistants. With mcp-builder.ai, teams can import OpenAPI 3.x or Swagger specs, review every operation, and publish only the endpoints that should be callable.
What you can do with a OpenAPI MCP server
A OpenAPI MCP server gives AI agents a typed, governed surface over your OpenAPI data instead of raw access. Some of the patterns teams build first:
- Generate MCP tools directly from OpenAPI or Swagger definitions
- Exclude risky operations and reshape parameters before publishing
- Keep tools aligned with API changes through controlled re-imports
- Map OAuth, API key, and bearer security schemes to MCP clients
Why a tailored MCP layer beats raw OpenAPI access
Letting every AI client speak OpenAPI directly means leaking credentials, fighting client-side SDK quirks, and re-implementing auth and observability for every model. A OpenAPI MCP server on mcp-builder.ai gives you one hosted surface that every MCP-compatible client can use safely.
Supporting those common OpenAPI interface patterns
mcp-builder.ai handles the OpenAPI-specific transport, auth, and schema work for you, so your tools stay clean even when the underlying interface is not.
- OpenAPI 3.0 and 3.1 import
- Swagger 2.0 backward compatibility
- Per-operation parameter and response shaping
- Security-scheme mapping for OAuth, API keys, and bearer
