### Description (declared)

# REST-to-MCP Adapter

**A Python library for converting REST API specifications into MCP (Model Context Protocol) tools for AI agents.**

Transform any REST API specification into tools that Claude, GPT, and other LLM-powered agents can use.

**Supported Formats:**
- OpenAPI 3.x (JSON, YAML)
- Swagger 2.x (JSON, YAML)
- OpenAPI Actions format (JSON)

## 🚀 Quick Start

```python
from adapter import (
    OpenAPILoader,
    Normalizer,
    ToolGenerator,
    ToolRegistry,
    APIExecutor,
    BearerAuth,
    MCPServer
)

# 1. Load OpenAPI spec
loader = OpenAPILoader()
spec = loader.load("https://api.example.com/openapi.json")

# 2. Normalize to canonical format
normalizer = Normalizer()
endpoints = normalizer.normalize_openapi(spec)

# 3. Generate MCP tools (auth params auto-filtered!)
generator = ToolGenerator(api_name="myapi")
tools = generator.generate_tools(endpoints)

# 4. Create tool registry
registry = ToolRegistry(name="My API")
registry.add_tools(tools)

# 5. Set up API executor with authentication
executor = APIExecutor(
    base_url="https://api.example.com",
    auth=BearerAuth(token="your-token")
)

# 6. Start MCP server (for Claude Desktop, etc.)
server = MCPServer(
    name="My API Server",
    version="1.0.0",
    tool_registry=registry,
    executor=executor,
    endpoints=endpoints
)
server.run()  # Claude can now use your API!
```
