Discover MCP tools that connect AI agents to external APIs, REST endpoints, and third-party services.
MCP Swagger Server 将任何符合 OpenAPI/Swagger 规范的 REST API 转换为 Model Context Protocol (MCP) 格式，让 AI 助手能够理解和调用您的 API。
Your agents are guessing at APIs. Give them the actual Agent-Native spec. 1500+ API's Ready To-Use skills, Compile any API spec into a lean, agent-native format. 10× smaller. OpenAPI, GraphQL, AsyncAPI, Protobuf, Postman.
A unified CLI for discovering and invoking tools across OpenAPI, MCP, GraphQL, gRPC, and JSON-RPC
Browse any app normally. Spectral captures the traffic, understands what each API call does, and generates MCP tools that AI agents can call directly.
Turn any MCP, OpenAPI, or GraphQL server into a CLI — at runtime, with zero codegen
```bash
# Run directly without installing
uvx mcp2cli --help
# Or install globally
uv tool install mcp2cli
```Turns any OpenAPI/Swagger API into an CLI with set of commands. One CLI command per endpoint.
