# API Schema Analyzer

This skill analyzes OpenAPI/Swagger and Postman collection schemas to extract endpoint information for generating MCP tools.

## Instructions

### Analyzing OpenAPI Schemas

1. **Load OpenAPI Spec**
   - Use script: `scripts/analyze-openapi.py <openapi.json|yaml>`
   - Extracts: endpoints, methods, parameters, request/response schemas

2. **Generate Tool Signatures**
   - Use script: `scripts/generate-tool-signatures.py <openapi.json> --lang=python|typescript`
   - Creates: Function signatures with type hints from schema

### Analyzing Postman Collections

1. **Parse Collection**
   - Use script: `scripts/analyze-postman.py <collection.json>`
   - Extracts: requests, parameters, headers, auth requirements

2. **Map to MCP Tools**
   - Use script: `scripts/map-to-mcp-tools.py <collection.json> --output=tools.json`
   - Creates: MCP tool definitions with parameter mapping

## Available Scripts

- **`scripts/analyze-openapi.py`** - Parse OpenAPI specs (v2, v3)
- **`scripts/analyze-postman.py`** - Parse Postman collections
- **`scripts/generate-tool-signatures.py`** - Generate function signatures
- **`scripts/map-to-mcp-tools.py`** - Map API endpoints to MCP tools
- **`scripts/extract-schemas.sh`** - Extract request/response schemas

## Examples

**Example 1: Analyze OpenAPI Spec**
```bash
# Extract all endpoints and parameters
./scripts/analyze-openapi.py api-spec.json

# Generate Python tool signatures
./scripts/generate-tool-signatures.py api-spec.json --lang=python
```

**Example 2: Map Postman to MCP**
```bash
# Analyze Postman collection
./scripts/analyze-postman.py my-api.json

# Generate MCP tool mappings
./scripts/map-to-mcp-tools.py my-api.json --output=mcp-tools.json
```

## Requirements

- Python 3.7+ with `pyyaml`, `jsonschema` packages
- Valid OpenAPI v2/v3 spec or Postman collection
- jq for JSON processing

## Success Criteria

- ✅ Schema parsed successfully
- ✅ All endpoints extracted with full details
- ✅ Parameter types correctly identified
- ✅ Tool signatures generated with proper types
