Three steps to MCP-powered APIs

1

Import your spec

Paste an OpenAPI JSON or YAML document, or provide a URL. Warpgate parses the full specification and extracts every operation.

2

Select your tools

Choose which API operations to expose as MCP tools. Skip the ones you don't need — import only what matters.

3

Configure auth

Set up bearer tokens, API keys via header or query parameter, or leave unauthenticated. Warpgate injects credentials on every request.

Capabilities

Every REST API speaks MCP

Path params, query params, headers, and request bodies are all mapped to the tool's input schema automatically. The tool name comes from the operation's operationId.

Automatic Parameter Mapping

Path, query, and header parameters become tool inputs.

Flexible Authentication

Bearer tokens, API keys via header or query.

Selective Tool Import

Import only the operations you need.

JSON & YAML Support

Paste raw specs or fetch from a URL.
